Thailand Driving Laws: IDP, Insurance & What Tourists Need to Know

Driving in Thailand offers incredible freedom to explore. But the legal requirements are stricter than many tourists realize, and the consequences of non-compliance can be severe — especially if you are in an accident without proper documentation.

Thailand has the second-highest road fatality rate in the world. More tourists are seriously injured or killed in road accidents than by any other cause. This guide covers everything: licensing, insurance, traffic law, police interactions, accident procedures, rental decisions, fuel, parking, toll roads, and driving in specific conditions.

Do You Need a License?

Yes. To drive legally in Thailand — including motorbikes and scooters — you need one of:

1. International Driving Permit (IDP) — the most common option for tourists
2. Thai driving license — if you are a long-term resident
3. Valid license from certain countries with a certified Thai translation (limited applicability)

A license from your home country alone is not sufficient in most cases. The common tourist belief that "my home license works internationally" is wrong for Thailand. Thai law requires either an IDP or a Thai license.

International Driving Permit (IDP): Complete Guide

An IDP is a standardized booklet that translates your home country driving license into multiple languages, including Thai. It is recognized under the 1949 Geneva Convention on Road Traffic (which Thailand signed) and the 1968 Vienna Convention.

Essential Rules

• Must be carried together with your original home country license — the IDP alone is not valid
• Must be obtained before you leave your home country (you cannot get one in Thailand)
• Valid for 1 year from date of issue
• Must match the vehicle class on your home license — if your home license does not include motorcycles, your IDP will not cover motorcycles either
• Cost: typically $15-50 USD depending on country

IDP Application Guide by Country

United States

Issuing organization: AAA (American Automobile Association) or AATA (American Automobile Touring Alliance/National Automobile Club)

AAA process:

• In person: Visit any AAA office. No appointment needed. Bring your valid US driver's license, two passport-size photos (some offices take photos on-site for a fee), completed application form, and $20 USD.
• Online/by mail: Download the application from aaa.com, include two photos, a photocopy of both sides of your driver's license, and $20. Mail to the address on the form.
• Processing time: In person — same day or next day. By mail — 4-6 weeks.
• Cost: $20 USD
• AAA membership required? No for IDPs, despite common misconception. Non-members can get IDPs at AAA offices.
• Motorcycle note: US driver's licenses have a motorcycle endorsement ("M" class). If your license does not have this endorsement, your IDP will not cover motorcycles. To add motorcycle endorsement, you need to pass a motorcycle skills test at your state DMV.

United Kingdom

Issuing organization: Post Office or online through the Post Office website

Process:

• Online: Apply at postoffice.co.uk/international-driving-permit. Upload a photo, enter license details, pay online.
• In person: Visit a Post Office branch that offers IDP services (not all branches do — check online). Bring your UK driving license, a passport photo, and payment.
• Processing time: Online — 5-7 business days by mail. In person — issued immediately.
• Cost: GBP 5.50
• Important: The UK issues two types of IDP — the 1949 Convention permit and the 1968 Convention permit. Thailand recognizes both, but the 1968 version is recommended. When applying, specify that you need the 1968 IDP.
• Motorcycle: UK licenses have separate motorcycle categories (A1, A2, A). Your IDP reflects what your license covers.

Australia

Issuing organizations: State automobile associations — NRMA (NSW), RACV (Victoria), RACQ (Queensland), RAA (South Australia), RAC (Western Australia), RACT (Tasmania), AANT (Northern Territory)

Process:

• In person: Visit your state's automobile association office with your Australian driver's license, a passport photo, and payment.
• Online: Most state associations offer online applications. Upload photo, enter license details.
• Processing time: In person — same day. Online — 5-10 business days.
• Cost: AUD 39-49 depending on state
• Motorcycle: Australian licenses separate car (C) and motorcycle (R) classes. If you only have a C class license, your IDP will not cover motorcycles.

Canada

Issuing organization: CAA (Canadian Automobile Association)

Process:

• In person: Visit any CAA office with your valid Canadian driver's license, two passport photos, and payment.
• Online/by mail: Available through some CAA regional offices.
• Processing time: In person — same day. Mail — 2-4 weeks.
• Cost: CAD 25
• Motorcycle: Canadian licenses have separate motorcycle class (M). Same rule — no M class, no motorcycle coverage.

Germany

Issuing organization: Local Straßenverkehrsamt (road traffic authority) or ADAC (German automobile club)

Process:

• ADAC offices: Bring Personalausweis or Reisepass, Führerschein (driver's license), biometric photo, and EUR 15. Issued same day.
• Straßenverkehrsamt: Same documents, slightly higher fee (EUR 15-20), may take 1-3 days.
• Cost: EUR 15-20
• Processing: Same day at ADAC; 1-3 days at government offices
• Motorcycle: German licenses have separate Klasse A (motorcycle). Your IDP reflects your license classes.

France

Issuing organization: Préfecture or sous-préfecture. Note that France requires applications through the government ANTS system for some document types, but IDPs are still processed at préfectures.

Process:

• Visit your local préfecture or sous-préfecture with your permis de conduire, passport photo, identity document, and application form.
• Cost: Free (one of the few countries where IDPs are free)
• Processing: 1-5 business days typically
• Motorcycle: French licenses separate car (B) and motorcycle (A) categories.

Japan

Issuing organization: JAF (Japan Automobile Federation)

Process:

• Visit a JAF office with your Japanese driver's license, passport, one passport photo, and JPY 2,350.
• Important: Japan issues IDPs based on the 1949 Geneva Convention. Thailand recognizes this.
• Cost: JPY 2,350
• Processing: Same day at JAF offices
• Motorcycle: Japanese licenses have separate motorcycle categories (原付, 普通二輪, 大型二輪). IDP reflects your categories.

South Korea

Issuing organization: Korean driver's license examination offices or Korean automobile associations

Process:

• Visit a driver's license examination office with your Korean license, passport, one passport photo, and KRW 8,500.
• Cost: KRW 8,500
• Processing: Same day
• Motorcycle: Korean licenses have separate two-wheeler category.

China

Issuing organization: China does not issue IDPs through the standard international system. Chinese driver's licenses are not part of the Geneva or Vienna conventions.

Workaround for Chinese tourists:

• Apply for an IDP through a third-party service in a country where you can obtain one (e.g., Hong Kong residents can get IDPs through the Hong Kong Automobile Association)
• Some services offer non-convention "international driving documents" — these are not official IDPs and may not be accepted by Thai police
• The safest option for Chinese nationals is to hire private drivers, use ride-hailing apps (Grab, Bolt), or obtain a Thai driving license if staying long-term

India

Issuing organization: Regional Transport Office (RTO) or local AAI (Automobile Association of India) affiliate

Process:

• Apply at your local RTO with your Indian driving license, passport, photos, and fees
• Cost: INR 500-1,000
• Processing: 3-7 business days
• Motorcycle: Indian licenses have separate motorcycle (MCWG) and car (LMV) categories.

Thai Driving License for Long-Stayers

If you are staying in Thailand long-term (on a non-immigrant visa, retirement visa, DTV, etc.), getting a Thai driving license is worthwhile. It is valid for 2 years (initially 1 year, then renewable for 5 years), accepted by police without question, and required for some insurance policies.

Step-by-Step Process

Step 1: Gather documents

• Passport with current valid visa
• Certificate of residence from your embassy (or immigration) — this is the most time-consuming document to obtain. Your embassy issues it for 500-2,000 THB, usually requiring an appointment. Processing takes 1-7 days depending on the embassy.
• Medical certificate from a Thai clinic or hospital (100-300 THB, takes 15-30 minutes — they test color blindness, depth perception, and reflexes)
• Your home country driving license (original)
• IDP (if you have one)
• Passport photos (2-3, 1-inch size)

Step 2: Visit the Department of Land Transport (DLT)

• Bangkok main office: Mo Chit area (near Chatuchak)
• Offices exist in every province
• Arrive by 8:00 AM — the process takes most of a day
• Bring all original documents plus photocopies of everything

Step 3: Take the written test

• Available in English on a computer
• 50 multiple-choice questions about Thai traffic laws
• Pass mark: 45/50 (90%)
• Common areas: right of way, traffic signs (Thai style), speed limits, alcohol limits
• Study materials: The DLT has a practice test booklet. Several apps and websites have practice questions. The test is not difficult if you study for 1-2 hours.

Step 4: Take the practical driving test

• For cars: Drive a course at the DLT office — forward parking, reverse parking, parallel parking, and a short road course
• For motorcycles: Ride a figure-8, stop at a line, ride over a narrow plank
• The tests are straightforward but specific to the DLT course layout
• Some DLT offices require watching a 1-2 hour safety video before the practical test

Step 5: Receive your license

• Issued same day if you pass
• Fee: 205 THB (car), 155 THB (motorcycle), 255 THB (both)
• First license valid for 1 year, then renewable for 5-year license
• Renewal requires a new medical certificate and vision test but no driving test

Total time: 1 full day at the DLT office, plus 1-7 days to get the embassy certificate beforehand. Total cost: 500-2,500 THB (embassy certificate + medical certificate + license fee)

Insurance Types: Deep Dive

Compulsory Insurance (Por Ror Bor / พ.ร.บ.)

All vehicles in Thailand must have compulsory third-party insurance, known as Por Ror Bor. When you rent any vehicle, this should be included — ask to see the sticker on the vehicle.

What it covers:

• Third-party injuries: up to 80,000 THB per person for medical expenses
• Death of third party: up to 300,000 THB
• Permanent disability of third party: up to 300,000 THB

What it does NOT cover:

• Your own injuries
• Your vehicle damage
• Third-party property damage (their vehicle, building, etc.)
• Injuries if you were driving without a valid license

In practice: Por Ror Bor is the bare minimum. The coverage limits are low by any standard — 80,000 THB ($2,300 USD) does not go far for serious medical treatment. It exists to ensure that accident victims receive at least some compensation, but it is insufficient for serious accidents.

Voluntary Insurance (Class 1, 2, 3)

Additional insurance purchased by vehicle owners or rental companies. When renting, ask specifically which class of voluntary insurance is included.

Class 1 (Comprehensive — ชั้น 1)

The best coverage available:

• Third-party liability: 500,000 to 10,000,000 THB (depending on policy)
• Your vehicle damage: Covered up to the vehicle's value
• Theft: Covered
• Fire: Covered
• Flood damage: Usually covered
• Personal accident: Covered for driver and passengers
• Cost: 15,000-40,000 THB/year for a car (pro-rated for rental periods)
• Deductible: Typically 1,000-5,000 THB per claim

When renting: If the rental company offers Class 1 insurance (or "full insurance" / "comprehensive"), take it. The extra 200-500 THB per day is worth it.

Class 2 (Third-Party + Theft + Fire — ชั้น 2)

• Third-party liability covered
• Theft and fire covered
• Your vehicle damage from accidents: NOT covered
• Less common for tourists — it is an odd middle ground

Class 3 (Third-Party Only — ชั้น 3)

• Third-party liability with enhanced limits (higher than Por Ror Bor)
• Your vehicle not covered for anything
• Cheapest voluntary option
• Adequate if you are a careful driver and the rental vehicle is low-value

Summary table:

| Coverage | Por Ror Bor | Class 3 | Class 2 | Class 1 | |----------|-----------|---------|---------|---------| | Third-party injury | 80K THB | Enhanced | Enhanced | Enhanced | | Third-party property | No | Yes | Yes | Yes | | Your vehicle damage | No | No | No | Yes | | Theft | No | No | Yes | Yes | | Fire | No | No | Yes | Yes | | Your injury | No | No | No | Yes | | Typical annual cost | 600-900 THB | 5,000-10,000 THB | 8,000-15,000 THB | 15,000-40,000 THB |

Insurance Claim Process

If you are in an accident with insurance:

1. Call the insurance company's hotline (number is on the insurance sticker or policy document). Rental companies should provide this number.
2. An insurance adjuster arrives at the scene — typically within 30-60 minutes in urban areas, longer in rural areas and on islands.
3. The adjuster photographs the scene, talks to both parties, and determines preliminary fault.
4. You sign the claim form. Read it before signing, even if it is in Thai — ask for translation or take a photo and use Google Translate.
5. If fault is clear and both parties have insurance: The insurance companies negotiate directly. You may not need to do anything further.
6. If fault is disputed: Police report becomes important. The insurance companies may take weeks to resolve.
7. For your vehicle damage (Class 1): Take the vehicle to an approved repair shop. Insurance pays directly or reimburses you.
8. For your injuries: Insurance covers hospital costs either directly (if the hospital accepts the insurance) or by reimbursement.

Your Travel Insurance

Your personal travel medical insurance is the most critical piece of coverage. Thai vehicle insurance may not cover your medical costs adequately, especially if you are on a motorbike.

Check that your travel insurance:

• Covers motorbike/scooter accidents — many standard policies exclude two-wheelers, or only cover them if you have a valid license (IDP with motorcycle class)
• Does not require a valid local license for medical coverage — some policies void coverage if you were driving without proper licensing
• Covers vehicle damage liability — if you damage the rental vehicle or someone else's property
• Has medical evacuation coverage — helicopter/ambulance evacuation from islands to mainland hospitals can cost 100,000+ THB
• Has a high enough coverage limit — 1,000,000 USD minimum is recommended for Thailand. Hospital bills for serious accidents can reach millions of baht.

Check our insurance guide for recommended policies.

Traffic Law Specifics

Driving Side

Thailand drives on the left side of the road (same as UK, Australia, Japan). The steering wheel is on the right side of the vehicle. If you are from a country that drives on the right, this adjustment takes 1-3 days. The most dangerous moments are:

• Turning at intersections (instinct pulls you to the wrong lane)
• Roundabouts (flow is clockwise)
• Pulling out from a parking spot onto a road
• After stopping for fuel or food (you forget and drift right)

Speed Limits

| Road Type | Speed Limit | Notes | |-----------|------------|-------| | Urban areas | 80 km/h | Often 50-60 km/h in residential areas | | Rural highways | 90 km/h | | | Motorways/expressways | 120 km/h | Minimum 60 km/h on expressways | | Construction zones | 60 km/h | | | School zones | 30 km/h | Often poorly marked |

Enforcement: Speed cameras exist on some highways and expressways. In urban areas, speed limits are loosely enforced. On rural roads, almost never enforced. However, exceeding the speed limit puts you at fault in any accident, which affects insurance claims and liability.

Right of Way Rules

• Main road has priority over side roads
• Traffic already in a roundabout has priority over entering traffic
• Vehicles on the right have priority at uncontrolled intersections (theory — in practice, the bigger vehicle goes first)
• Emergency vehicles with sirens/lights have absolute priority
• U-turn traffic must yield to all through traffic

Overtaking Rules

• Overtake on the right (since driving is on the left)
• Do not overtake on curves, hills, bridges, intersections, or railroad crossings
• Flash headlights before overtaking as a warning
• Reality: Overtaking rules are routinely ignored. Trucks, buses, and motorbikes overtake on both sides, often simultaneously. Drive defensively.

Intersection Rules

Thai intersections are... unique:

• Traffic lights are mostly obeyed, but running red lights happens, especially by motorbikes
• Left turns on red are sometimes permitted (equivalent to right turn on red in US right-hand driving countries) — but not always, and it varies by intersection
• Many intersections have dedicated U-turn lanes — U-turns are a primary navigation method in Thailand because many roads have center dividers
• Police-controlled intersections (with an officer directing traffic) are common in busy areas and override traffic lights

U-Turn Rules

U-turns deserve special attention because they are fundamental to Thai road navigation:

• Many Thai roads have center dividers (median barriers), so you cannot turn left across traffic
• Instead, you drive past your destination, find a U-turn point, make the U-turn, and drive back on the opposite side
• Dedicated U-turn lanes are common — they have their own traffic lights or gaps in the median
• When making a U-turn, you must yield to all through traffic
• U-turn points can be 500 meters to several kilometers apart — check Google Maps for the nearest one

Alcohol Limit

• Legal BAC limit: 0.05% (lower than the US 0.08%, same as Australia)
• For new drivers (under 5 years licensed): 0.02%
• Penalties: Fines up to 20,000 THB, up to 1 year imprisonment, license suspension
• Breathalyzer checkpoints: Common on weekend nights, especially near nightlife areas and on main roads after midnight
• Practical reality: Drunk driving is extremely common in Thailand despite the law. Be a defensive driver, especially at night and on weekends.

Police Checkpoint Complete Guide

Police checkpoints are a regular part of driving in Thailand. Understanding them reduces stress significantly.

Types of Checkpoints

License/document checkpoints: Check for valid license, vehicle registration, and insurance. Most common daytime checkpoint.

Sobriety checkpoints: Breathalyzer tests. Most common Friday/Saturday nights, 10 PM to 2 AM.

Helmet checkpoints: Specifically checking motorcycle riders for helmets. Very common on islands (Koh Samui, Koh Phangan, Phuket) and in cities.

General police presence: Officers standing by the road, selectively stopping vehicles. May check for any of the above.

What They Check

1. Driver's license — IDP + home license, or Thai license
2. Helmet (for motorbikes) — both rider and passenger
3. Vehicle registration (the vehicle's green booklet — rental companies should provide a copy)
4. Insurance sticker (Por Ror Bor sticker should be visible on the vehicle)
5. Sobriety — breathalyzer if they suspect drinking, or at dedicated sobriety checkpoints
6. Vehicle condition — lights, mirrors, general roadworthiness (rarely for rental vehicles)

How to Behave at a Checkpoint

1. Slow down and stop when directed. Do not try to turn around or avoid the checkpoint — this draws serious attention.
2. Turn off your engine (motorbike) or roll down your window (car).
3. Be polite and calm. "Sawadee krub/ka" (hello) goes a long way.
4. Present your IDP and home license immediately when asked for a license. Having them together and easily accessible speeds things up.
5. If asked to take a breathalyzer, cooperate. Refusal can be treated as admission of intoxication.
6. If you have all documents and are sober, the interaction typically takes 30 seconds to 2 minutes.

Fine Payment Process

If you are fined (no license, no helmet, speeding, etc.):

Legitimate process:

1. The officer writes an official ticket (ใบสั่ง / bai sang) with the offense, fine amount, and payment instructions.
2. You have 7 days to pay the fine at the police station listed on the ticket.
3. Fine amounts are standardized: 500 THB for no helmet, 500-1,000 THB for no license, 400-1,000 THB for phone use, etc.
4. You receive an official receipt.

On-the-spot payment (the gray area):

• Some officers will offer to settle the fine on the spot for cash, often less than the official fine amount.
• This is technically a bribe, not an official fine payment. You will not receive an official receipt.
• Paying on the spot is extremely common and widely practiced. Many tourists and Thais pay this way.
• The risk: You have no receipt, so if the same "fine" shows up later as unpaid, you have no proof of payment.
• Our recommendation: Ask for the official ticket and pay at the police station. This is the legal process. If the officer insists on on-the-spot payment and you choose to pay, note the officer's badge number and the amount.

Receipt vs. Bribe: How to Tell

| Factor | Official Fine | Informal Payment | |--------|-------------|-----------------| | Paperwork | Written ticket with carbon copy | No paperwork | | Receipt | Official receipt at police station | No receipt | | Amount | Standardized (posted online) | Often "negotiated" — typically lower than official fine | | Where you pay | Police station | Roadside | | Record | Documented | Undocumented |

Accident Liability System

Comparative Negligence

Thai traffic law uses a comparative negligence system, meaning fault can be shared between parties. An accident might be ruled 70/30, 60/40, or any other split.

However, certain factors create automatic or near-automatic fault:

| Factor | Effect on Fault | |--------|----------------| | Driving without valid license | Strong presumption of fault regardless of circumstances | | Not wearing a helmet (motorbike) | Contributory negligence — reduces your compensation even if the other party was primarily at fault | | Driving under the influence | Strong presumption of fault | | Exceeding speed limit | Contributory negligence | | Running a red light | Primary fault | | Vehicle with no insurance | Additional penalties | | Larger vehicle | Informal bias — larger vehicles often bear more practical responsibility |

What "Big Vehicle Bias" Means

In practice (though not strictly in law), there is a strong cultural presumption that the larger vehicle bears more responsibility. If a car hits a motorbike, the car driver is often expected to cover costs even if the motorbike rider was technically at fault. If a truck hits a car, the truck is expected to bear more responsibility.

This is especially relevant for tourists renting cars — if you are in an accident with a motorbike, be prepared for the assumption that you bear significant responsibility.

The Police Report

For any accident involving injuries or significant property damage:

1. Call 191 (police) or 1155 (tourist police — if you need English)
2. Police arrive and document the scene
3. Both parties go to the police station to file a report (often the same day or within 24 hours)
4. The police report establishes a preliminary determination of fault
5. This report is used by insurance companies and, if necessary, courts

Important: Stay at the scene until police arrive. Leaving the scene of an accident is a criminal offense in Thailand, regardless of fault.

Court Process (Rare for Tourists)

Most tourist-involved accidents are resolved through insurance. Court involvement happens when:

• Someone was seriously injured or killed
• Insurance coverage is insufficient
• Fault is disputed and cannot be resolved between insurance companies
• Criminal charges are filed (DUI, leaving the scene, reckless driving causing death)

If you end up in the Thai legal system:

• Contact your embassy immediately
• Hire a Thai lawyer — your embassy can recommend English-speaking attorneys
• Do not sign any document you do not understand
• Court processes can take months to years

Rental Car vs. Motorbike: Detailed Comparison

| Factor | Rental Car | Scooter/Motorbike | |--------|-----------|-------------------| | Daily cost | 800-2,000 THB (compact), 1,500-3,500 THB (SUV) | 200-300 THB (125cc scooter), 500-1,000 THB (big bike) | | Fuel cost | 50-70 THB/liter gasoline, 500-1,000 THB/day typical | 50-70 THB/liter, 50-150 THB/day typical | | Insurance included | Usually Class 1 or Class 3 (ask specifically) | Usually only Por Ror Bor (compulsory minimum) | | IDP requirement | Enforced by most rental companies | Often not checked by rental shops (but still legally required) | | Deposit | 5,000-20,000 THB or credit card hold | 2,000-5,000 THB cash or passport (never give your passport) | | Parking | Challenging in cities, usually available at hotels | Easy everywhere | | Road comfort | AC, protection from rain, comfortable on long drives | Exposed to weather, uncomfortable beyond 1-2 hours | | Safety | Significantly safer — protected by vehicle body | Extremely dangerous — you are the crumple zone | | Accident risk | Moderate (if experienced with left-side driving) | Very high (Thailand's road fatality rate is driven largely by motorcycle accidents) | | Best for | Families, road trips, northern Thailand, long distances | Islands (short distances), experienced riders, solo budget travelers | | Worst for | Bangkok (traffic, parking), narrow island roads | Long distances, rain, night driving, anyone without motorcycle experience |

Rental Tips: Cars

• Book through international platforms (Rentalcars.com, Hertz, Budget, Avis) for better insurance and clearer contracts
• Local companies (Thai Rent A Car, Chic Car Rent) are cheaper but insurance terms are vaguer
• Inspect the vehicle thoroughly before driving away. Photograph every scratch, dent, and mark. Email photos to the rental company with date/time.
• Fuel policy: Most rentals are full-to-full. Return with a full tank.
• One-way rentals (pick up in Chiang Mai, drop off in Bangkok) are available but cost extra (2,000-5,000 THB surcharge).
• GPS/navigation: Use Google Maps on your phone with a dashboard mount. Rental GPS devices are unnecessary and overpriced.

Rental Tips: Motorbikes

• Never leave your passport as deposit. This is common practice at island rental shops, and it is a terrible idea. You have no leverage if the bike is damaged, they "find" pre-existing damage, or you need your passport for any reason. Leave a cash deposit (2,000-5,000 THB) or a photocopy of your passport instead. Walk away from any shop that insists on holding your passport.
• Photograph the bike completely before renting. Every angle, every scratch. The single most common tourist scam on Thai islands is rental shops claiming pre-existing damage was caused by you.
• Check tires — worn, bald tires are common on rental scooters and are deadly in rain.
• Check brakes — test both front and rear brakes before leaving the shop. Weak brakes on a steep island road are a crisis.
• Check lights — headlight, tail light, turn signals. Non-functional lights are a checkpoint fine and a safety hazard.
• Get a helmet from the rental shop. It will be a cheap, ill-fitting helmet, but it is better than nothing and is required by law. If you plan to ride frequently, buy your own (full-face helmets available at shops in Phuket, Samui, Bangkok for 500-2,000 THB).

Fuel Guide

Gasoline Types

Thai gas stations sell multiple fuel grades:

| Fuel Type | Color Code | Octane | Price (approx. THB/liter) | Use | |-----------|-----------|--------|--------------------------|-----| | Gasohol 91 (E10) | Regular green | 91 | 33-36 | Most cars and scooters | | Gasohol 95 (E10) | Premium green | 95 | 36-39 | Higher-performance cars | | Gasohol E20 | E20 label | 95 | 33-35 | Vehicles designed for E20 only | | Gasohol E85 | E85 label | 105+ | 27-30 | Flex-fuel vehicles only (rare) | | ULG 95 | Yellow | 95 | 40-43 | Older vehicles not compatible with Gasohol | | Diesel | Biodiesel label | N/A | 30-34 | Diesel vehicles only |

For rental scooters: Use Gasohol 91. It is the cheapest compatible fuel and what 99% of scooters use. For rental cars: Use Gasohol 91 or 95 (check the fuel cap sticker). Most rental cars use 91.

How to Fuel Up

Full-service (most common): Pull up to the pump, tell the attendant what fuel and how much. "Gasohol 91, tem tank" (full tank) or "Gasohol 91, 200 baht" (200 THB worth). They pump, you pay cash or sometimes card.

Self-service: Less common but exists at some stations. Same as self-service anywhere — select fuel, insert payment, pump.

Island gas stations: On smaller islands (Koh Tao, Koh Lipe, etc.), there may not be proper gas stations. Instead, you buy fuel from roadside stalls — bottles of gasoline (usually Gasohol 91) sold in liter bottles for 40-60 THB. It is the same fuel, just marked up for island convenience.

Parking Rules

Legal parking:

• Marked parking spaces (white or yellow lines)
• Shopping mall parking garages (usually free for 1-3 hours, then 20-40 THB/hour)
• Hotel parking (usually free for guests)
• Designated parking lots (20-60 THB/day in cities)

Illegal parking:

• Red and white curbs — no parking at any time
• Yellow and white curbs — no stopping
• On bridges, in tunnels, at intersections
• Blocking fire hydrants
• Double parking (common practice in Bangkok but technically illegal)

Consequences of illegal parking:

• Wheel clamp: 500-1,000 THB removal fee. Very common in Bangkok. Takes 30 minutes to 2 hours to remove after payment.
• Towing: 500-1,000 THB towing fee plus daily storage. Your vehicle goes to a police impound lot. Retrieval requires your license, vehicle registration, and payment.
• Ticket: 200-500 THB fine

Bangkok parking tip: Do not drive in central Bangkok. Traffic is terrible, parking is scarce and expensive, and the BTS/MRT system is efficient. If you must drive, use shopping mall parking garages.

Toll Roads and Expressways

Bangkok and surrounding areas have an extensive expressway network that significantly speeds up travel.

Expressway System

• Don Muang Tollway: Connects Don Mueang airport to central Bangkok. 25-75 THB depending on distance.
• Bangkok Expressway (BECL): Network covering central and suburban Bangkok. 25-90 THB per section.
• Motorway 7: Bangkok to Pattaya/Eastern Seaboard. 50-165 THB.
• Motorway 9: Bangkok outer ring road. 20-115 THB.

How Tolls Work

• Cash lanes: Pay with cash (bills and coins). Have small bills ready — 20 and 50 THB notes.
• Easy Pass: Electronic toll card. Not worth it for tourists unless you are driving extensively. Available at expressway offices for 200 THB deposit.
• M-Pass / M-Flow: Electronic tags for newer motorways. Again, not needed for tourists.

Tips

• Download the EXAT app (Expressway Authority of Thailand) for current toll prices and route planning
• Expressways are well-maintained, well-lit, and significantly safer than surface roads
• Signs are in Thai and English on major expressways
• Do not stop on the expressway except in emergencies — there are service areas every 40-60 km on motorways

Driving in Specific Conditions

Mountains (Northern Thailand)

• Steep grades: Roads to Doi Inthanon, Doi Suthep, and through the Mae Hong Son loop have steep, winding sections. Use low gear when descending — do not rely on brakes alone.
• Hairpin turns: Many mountain roads have tight switchbacks. Honk before blind corners.
• Fog: Common in cool-season mornings (November-February). Slow down dramatically when visibility drops.
• Landslides: During monsoon (June-October), mountain roads are susceptible to landslides. Check road conditions before attempting mountain passes. The Mae Hong Son loop is particularly affected.
• Altitude: Doi Inthanon reaches 2,565 meters — temperatures drop to 5-10C at the summit in cool season. Not relevant to driving performance but relevant to clothing.

Islands

• Road quality varies wildly. Main island roads are usually paved (Samui, Phuket) but secondary roads on smaller islands (Koh Phangan, Koh Lanta, Koh Chang) may be unpaved, potholed, steep, and narrow.
• Steep hills: Koh Phangan and Koh Tao have notoriously steep roads. Gradient can exceed 25% — scooters stall, cars struggle. If your rental scooter lacks the power to climb a hill, do not try — you will lose control rolling backward.
• Animals on roads: Dogs, chickens, and monitor lizards are common road hazards on islands. They move unpredictably.
• No road shoulders. Most island roads have no shoulder — the road ends and the ditch begins. Running off the edge means a drop.
• Limited medical facilities. Accidents on islands mean slow medical response and potential boat transfer to the mainland for serious injuries.

Bangkok

• Do not drive in Bangkok. The traffic is legendary for a reason. Average speeds during rush hour are 10-15 km/h. Parking is scarce. The BTS and MRT are fast, reliable, and cover most tourist areas. Grab (ride-hailing) and taxis are cheap and abundant.
• If you must drive: Use Google Maps with real-time traffic. Use expressways to bypass surface traffic. Avoid rush hours (7-9 AM, 5-8 PM). Budget 2-3x the estimated driving time.
• Motorbike taxis (orange vests) are the fastest way through Bangkok traffic but are terrifying for the uninitiated.

Rural Thailand

• Poorly lit or unlit roads. Many rural roads have no street lights. Drive with high beams (switch to low when other vehicles approach) and watch for obstacles — vehicles without lights, pedestrians, animals.
• Trucks and buses. Intercity buses and heavy trucks dominate rural highways and drive aggressively. Do not play chicken with a bus.
• Railroad crossings. Some rural crossings have no barriers or lights. Slow down and look both ways at every crossing.

Night Driving

• Avoid it if possible. Night driving in Thailand is significantly more dangerous than daytime: more drunk drivers, poor lighting, animals on roads, and vehicles running without lights.
• If you must drive at night: Stick to major highways and expressways. Keep speed moderate. Be hyper-alert for motorbikes without lights (extremely common). Do not drive on unfamiliar island or mountain roads at night.

International License FAQ

Q: Can I drive in Thailand with just my home country license? A: Technically no. Thai law requires either an IDP + home license, or a Thai license. In practice, some rental companies will rent to you with just a home license, and some police officers may accept a non-Thai license, but you are not legally covered. If you are in an accident without an IDP, your insurance may be voided and you may be considered at fault.

Q: I have an IDP for cars. Can I ride a scooter? A: Only if your home license (and therefore your IDP) includes motorcycle class. A car-only IDP does not cover scooters or motorbikes of any size, including 125cc scooters.

Q: Where can I get an IDP in Thailand? A: You cannot. IDPs must be obtained in your home country before traveling. If you arrive in Thailand without one, you can either get a Thai license (requires a valid long-stay visa and takes a day) or use alternative transport.

Q: My IDP expired while I'm in Thailand. What now? A: You cannot renew an IDP in Thailand. Options: have someone at home apply for a new one and mail it to you, get a Thai license if you are on a long-stay visa, or stop driving and use taxis/Grab.

Q: Do electric scooters and e-bikes require a license? A: Currently a gray area. Electric scooters (the standing type) are not technically street-legal in Thailand. E-bikes that resemble motorcycles are treated as motorcycles. Pedal-assist bicycles generally do not require a license.

Q: I have a UK/Australian license. Does left-hand drive experience help? A: Yes. If you are from a left-hand-drive country, you will find Thai road habits familiar. The IDP requirement still applies, but the driving itself will feel natural.

Q: What about international car rental chains — do they verify IDP? A: International chains (Hertz, Avis, Budget) almost always require and verify your IDP. Local Thai rental companies are less consistent — some check, some do not. Even if a rental company does not check, the law still requires it.

Q: Can I get motorcycle endorsement added to my license quickly? A: This depends on your home country. In the US, some states offer 1-2 day motorcycle safety courses that qualify you for endorsement. In the UK, a CBT (Compulsory Basic Training) takes one day. Plan ahead — getting endorsement takes time and testing in most countries.

Q: What happens if I'm stopped without any license at all? A: Fine of 1,000-2,000 THB for driving without a license. Your vehicle may be impounded until a licensed driver comes to collect it. If this happens during or after an accident, you face much more serious consequences (see fault/liability section above).

Q: Is an International Driving Document from an online service the same as an IDP? A: No. Various online services sell "International Driving Documents" or "International Driving Licenses" that are not official IDPs issued under the Geneva or Vienna conventions. These may not be recognized by Thai police or insurance companies. Only get an IDP from your country's official issuing authority (AAA in the US, Post Office in the UK, CAA in Canada, etc.).

Key Takeaways

1. Get an IDP before your trip. It costs $15-50 USD, takes minutes to days depending on method, and is legally required for driving in Thailand.
2. Check your IDP covers motorcycles if you plan to ride a scooter. Most car licenses do not include motorcycle endorsement. This is the most common licensing mistake tourists make in Thailand.
3. Understand your insurance. Know what class of insurance your rental includes. Ask specifically. Class 1 is worth the extra cost. Check your travel insurance covers motorbike accidents.
4. Always wear a helmet on motorbikes. It is the law, it saves lives, and riding without one voids your insurance.
5. Keep license and IDP on you at all times. Police checkpoints are common and random.
6. Know what to do in an accident: Call 1669 (medical), 191 (police), 1155 (tourist police). Stay at the scene. Photograph everything.
7. Drive defensively. Thailand's roads are among the most dangerous in the world. Assume other drivers will not follow rules.
8. Avoid driving at night and in heavy rain when possible.
9. Never leave your passport as a motorbike rental deposit. Cash deposit or photocopy only.
10. Consider not driving. Grab, taxis, songthaews, trains, and buses cover most of Thailand. The freedom of driving must be weighed against the risk, especially for motorbikes.
