License Requirements for Motorcycles and Scooters

Every motorized two-wheeler in Thailand requires a motorcycle license to ride legally — and that includes the small 110cc scooters that rental shops hand out to tourists without a second thought. There is no exception for engine size, automatic transmission, or electric scooters. If it has a motor and two wheels, you need a motorcycle license. For short stays under three months, you can ride with your home country motorcycle license paired with a valid International Driving Permit (IDP) that includes a motorcycle endorsement. For stays longer than three months, you need to obtain a Thai motorcycle driving license from the Department of Land Transport (DLT). The temporary Thai motorcycle license costs 105 THB and is valid for two years. A five-year license costs 255 THB. Both require passing a written test (90% score on 50 questions), aptitude tests, and a practical riding exam for new applicants. If you are converting a foreign motorcycle license, the practical test is waived.

A Car License Does NOT Cover Motorcycles

This is the single most common and most costly misconception among foreigners in Thailand. Your car driving license — whether Thai, foreign, or international — does not authorize you to ride any motorcycle or scooter. A car license and a motorcycle license are entirely separate documents with separate tests and separate endorsements. An IDP based on a car-only license from your home country does not cover motorcycles either. If your home country license only shows car categories (such as Category B in European licenses), your IDP inherits those same limitations. To ride legally, you need either a dedicated motorcycle license from your home country reflected on your IDP, or a Thai motorcycle license obtained at a DLT office. Many tourists assume that because rental shops do not ask for a motorcycle license, one is not required. This is incorrect. Rental shops face minimal enforcement and are motivated by profit, not your legal protection. The responsibility for having a valid license falls entirely on the rider.

Penalties for Riding Without a License

Riding with no license at all is punishable under the Motor Vehicle Act by a fine of up to 1,000 THB, up to a month in jail, or both. Riding on an expired or suspended license carries a fine of up to 2,000 THB. Police can also impound the bike: in Phuket, police say an unlicensed rider's vehicle is impounded and the rental shop is fined as well. The fine is the small part of the risk. If you crash without a valid motorcycle license, voluntary insurance can refuse to pay for the bike, compulsory Por Ror Bor pays an at-fault unlicensed rider only its initial medical payment of up to 30,000 THB, and travel insurance policies commonly exclude riding without the license the law requires. Hospital bills for a serious crash run far past 30,000 THB. If the accident causes injury or death to another person, you face potential criminal charges under Thai law, and lacking a valid license significantly worsens your legal position. Thai courts view unlicensed riding as negligence, which can increase both criminal penalties and civil liability for damages.

Helmet Law: Up to 2,000 THB, Double With a Bare-Headed Passenger

Section 122 of the Land Traffic Act requires the rider and every passenger to wear a helmet, with no exception for short trips or low speeds. The fine is up to 2,000 THB, and a rider who carries a passenger without a helmet can be fined double. The rule isn't new, but enforcement is: on 1 June 2025 the Royal Thai Police started its Safe Roads Project, enforcing the helmet law strictly on 94 selected roads across the country. Away from those roads and checkpoints, enforcement is still patchy. Wear one anyway. The Department of Disease Control says 84% of motorcyclists admitted to hospital between 2020 and 2024 weren't wearing a helmet. Cheap open-face helmets are sold everywhere; a full-face helmet with an ECE or DOT certification is worth the extra money.

Where Motorcycles Can and Cannot Ride

Motorcycles are prohibited from all expressways and motorways in Thailand. This includes the elevated tollways in Bangkok (such as the Sirat Expressway and Chalerm Maha Nakhon Expressway) and the inter-city motorways connecting major cities. Ride onto one and you can expect to be stopped, fined and sent back to the exit. On regular roads, motorcycles should ride in the leftmost lane on multi-lane roads. In practice, Thai motorcycle riders weave through traffic and ride between lanes, but this is technically not permitted and significantly increases accident risk. On single-lane roads, motorcycles follow the same rules as other vehicles. Motorcycles are allowed on all regular highways, urban streets, and rural roads throughout the country. In some cities, there are designated motorcycle lanes marked with motorcycle symbols on the road surface — use these where available.

Speed Limits for Motorcycles

Motorcycles have lower limits than cars. Under the speed regulation in force since 22 July 2022, a motorcycle may do 60 km/h in Bangkok, Pattaya and other municipal or community areas, 70 km/h outside them, and 80 km/h on roads with at least two lanes in each direction and a central divider. Big bikes (400cc and up, or 35 kW and up) get 80, 90 and 100 km/h on the same roads. On national highways the Department of Highways limit is 80 km/h for motorcycles and 110 km/h for big bikes. Posted signs override all of these. Motorcycles are banned from expressways and motorways, so the 120 km/h limit there never applies to you. Speed cameras and radar checks are common on main highways, and camera tickets are sent to the bike's registered owner.

Passenger Rules

Thai law allows a maximum of one passenger on a motorcycle, for a total of two people on the bike. Carrying more than one passenger is illegal and carries a fine, though enforcement is admittedly lax in many areas — you will regularly see Thai families of three or four on a single scooter. All passengers must wear helmets under Section 122 of the Land Traffic Act, and the rider pays double if they don't. The Department of Disease Control advises that children too young to wear a helmet shouldn't ride at all, and that a rider carrying a young child should stay below 50 km/h. For passengers, sitting sideways (side-saddle) is common in Thailand but is dangerous and not recommended. Passengers should sit astride the bike facing forward, with feet on the passenger pegs. Proper footwear is important for passengers as well — flip-flops and sandals offer zero protection in even a minor fall.

Insurance Requirements and What Happens Without a License

Every registered motorcycle in Thailand must carry compulsory insurance, Por Ror Bor. For a private bike it costs 161.57 THB up to 75cc, 323.14 THB for 75-125cc, 430.14 THB for 125-150cc and about 645 THB above that. It covers injury and death for anyone hurt in a crash involving the bike, but not damage to the bike or other property. Voluntary insurance (Class 1, 2+ or 3+) adds that cover and is optional. Here is what the license changes. Por Ror Bor still pays out if the rider had no license, but if that rider caused the crash, they get only the initial payment: up to 30,000 THB for medical bills, or 35,000 THB for death or permanent disability. A voluntary insurer can refuse to pay for your own bike, and most travel insurance policies exclude riding without the license the law requires. Anything above those limits, including other people's claims against you, comes out of your own pocket, and that gap costs far more than any police fine.

Police Crackdowns on Unlicensed Foreign Riders

Phuket shows where enforcement is heading. Phuket Provincial Police recorded 30,551 traffic cases in 2025, and 26,515 of them were for driving without a license. In cases involving rental vehicles and unlicensed driving, police counted 23,646 offenders: 2,745 Thai and 20,901 foreign, led by Russian (11,855), Chinese, British and French nationals. 4,437 cases involved a rented car or motorbike, and police seized 1,737 vehicles. Rental businesses are in the firing line too: the province is checking rental companies with the Revenue Department, and police say the rental shop is fined along with the unlicensed rider. At a checkpoint, officers look for a valid motorcycle license (a Thai license, or your home license with an IDP that covers motorcycles), helmets on rider and passenger, and the bike's registration. Renting a scooter and riding it without the right paperwork is a bigger gamble every year.

Thailand Motorcycle Safety Statistics

The numbers are grim. In 2024, 17,447 people died on Thailand's roads and 14,144 of those deaths were linked to motorcycles, according to the Department of Disease Control: about 39 a day. Between 2020 and 2024, motorcycles accounted for around 80% of road deaths, and 84% of motorcyclists admitted to hospital weren't wearing a helmet. These are not abstract statistics. As a motorcycle rider in Thailand, you face a level of road risk that is dramatically higher than in most Western countries. Contributing factors include inconsistent road quality, poorly lit rural roads, stray animals, vehicles making unexpected turns, and a general driving culture that is less predictable than what many foreigners are accustomed to. Alcohol is a major factor — a significant proportion of fatal motorcycle accidents involve riders who have been drinking. Visitors add their own risks: left-hand traffic, unfamiliar road habits, and bikes rented without any training or license check.

Renting a Motorcycle vs Owning

Rental costs for a standard 125cc scooter range from 150 to 300 THB per day, with monthly rates dropping to 2,500 to 4,000 THB. Larger bikes (300cc and above) rent for 500 to 1,500 THB per day. For stays of several months or longer, buying a used scooter often makes more financial sense: a new Honda Wave 110i starts at 39,000 THB, a used one costs less, and a well-kept bike can be sold on when you leave (see our guide to buying a motorcycle). When renting, never hand over your passport as a deposit. Offer a photocopy of your passport instead, or leave a cash deposit. If the rental shop insists on holding your original passport, walk away and find another shop. Always photograph the bike thoroughly before riding away, documenting every scratch and dent. Get a written rental agreement that specifies the daily rate, deposit amount, and the bike's existing condition. Confirm whether the rental includes insurance and what the deductible is. Many rental shops include only compulsory insurance, leaving you liable for damage to the bike itself.

Essential Safety Tips for Riding in Thailand

Always wear a full-face helmet — not the thin plastic novelty helmets sold at some shops. Wear closed-toe shoes, long pants, and a jacket or long-sleeved shirt. Ride on the left side of the road and stay in the leftmost lane on multi-lane roads. Drive defensively and assume that other road users will make unexpected moves — because they will. Avoid riding at night whenever possible, as road hazards are harder to see and drunk driving rates increase significantly after dark. Watch for sand, gravel, and oil patches on the road surface, especially on curves and at intersections. Never drink and ride — Thailand's legal blood alcohol limit is 0.05% (0.02% for riders under 20), and alcohol is a factor in a large proportion of fatal motorcycle crashes. Keep your speed moderate, particularly on unfamiliar roads. Be constantly aware that Thailand drives on the left — this is especially dangerous at intersections where your instinct may be to look the wrong way. Get proper insurance before riding. Carry your license and IDP at all times. Avoid riding in heavy rain when visibility and road grip are severely compromised. Watch for stray dogs, which are common on Thai roads and can cause serious accidents. Use your mirrors and signal before changing lanes or turning.

Frequently Asked Questions

Do I need a motorcycle license to ride a scooter in Thailand?
Yes. All motorized two-wheelers in Thailand require a motorcycle license, regardless of engine size or transmission type. This includes small automatic scooters like the Honda Click and Honda Wave. A car license does not cover scooters.
Can I ride a motorcycle in Thailand with just my car license and IDP?
No. An IDP based on a car-only license does not authorize motorcycle riding. Your IDP only covers the vehicle categories listed on your domestic license. You need a motorcycle endorsement on your home license (reflected in your IDP) or a separate Thai motorcycle license.
What is the fine for riding without a helmet in Thailand?
Up to 2,000 THB under Section 122 of the Land Traffic Act, and the rider can be fined double if a passenger isn't wearing one. Police have enforced the rule strictly since 1 June 2025 under the Royal Thai Police's Safe Roads Project. Helmets are mandatory for riders and passengers at all times.
What happens if I have an accident without a motorcycle license?
Compulsory Por Ror Bor still pays, but if you caused the crash it pays only its initial amount: up to 30,000 THB for medical bills. A voluntary insurer can refuse to cover the bike, and most travel insurance excludes unlicensed riding, so everything above that, including other people's claims against you, is yours to pay. You can also face a fine of up to 1,000 THB for riding unlicensed, and criminal charges if someone is hurt.
Can motorcycles use expressways in Thailand?
No. Motorcycles are prohibited from all expressways and motorways in Thailand, including Bangkok's elevated tollways and the inter-city motorways. Ordinary highways are fine: the national-highway limit is 80 km/h for motorcycles and 110 km/h for bikes of 400cc and up.
How much does it cost to rent a motorcycle in Thailand?
A standard 125cc automatic scooter rents for 150 to 300 THB per day, or 2,500 to 4,000 THB per month. Larger bikes (300cc+) cost 500 to 1,500 THB per day. Never hand over your passport as deposit — offer a photocopy or cash deposit instead.
Are police really cracking down on tourists riding without a license?
Yes. Phuket police recorded 26,515 cases of driving without a license in 2025, and 20,901 foreigners were among the offenders in unlicensed-driving and rental-vehicle cases. Checkpoints on tourist routes check the license, helmets and the bike's registration.
How do I get a Thai motorcycle license?
You need a non-immigrant visa, a Certificate of Residence from Immigration, a medical certificate, and you must pass a written test (45 out of 50), aptitude tests, and a practical riding test. If converting a foreign motorcycle license, the practical test is waived. The temporary license costs 105 THB and is valid for two years.
How dangerous is riding a motorcycle in Thailand?
Very. The Department of Disease Control counted 17,447 road deaths in 2024, and 14,144 of them were linked to motorcycles. Motorcycles account for around 80% of Thai road deaths, and 84% of motorcyclists admitted to hospital between 2020 and 2024 weren't wearing a helmet.
What speed limit applies to motorcycles in Thailand?
60 km/h in Bangkok, Pattaya and other municipal areas, 70 km/h outside them, and 80 km/h on divided roads with two or more lanes each way. Bikes of 400cc and up get 80, 90 and 100 km/h. On national highways the limit is 80 km/h (110 km/h for big bikes). Posted signs take priority.
