IDP Requirements in Thailand
For most tourists, an International Driving Permit (IDP) is considered essential when driving in Thailand. Thai police expect foreign drivers to carry an IDP alongside their original driver’s license, and car rental companies may refuse to release a vehicle without it.
Accepted Licenses
Your home country license alone is not enough if it is not in Thai or clearly readable by local authorities. An IDP acts as an official translation and proof that your license is valid. Tourists from the US, UK, Europe, Australia, Canada and the Middle East are strongly advised to carry an IDP at all times when driving.
Driving Rules & Road Laws
Thailand drives on the left-hand side of the road. Seatbelts are mandatory, mobile phone use is only allowed with a proper hands-free system, and drunk-driving laws are strict. Speed limits are usually 50 km/h in cities, 90 km/h on open roads, and up to 120 km/h on expressways. Police checkpoints are common, especially at night and weekends.
Car Rental Requirements
Car rental companies such as Avis, Budget, Hertz and local brands will normally ask for three things: your passport, your national driver’s license and a valid IDP. Minimum age is typically 21–23 years, with young-driver surcharges under 25. A credit card in the main driver’s name is usually required as a deposit.
Local Driving Tips
Traffic in Bangkok and other major cities can be intense. Use toll expressways for safer, faster travel. Avoid driving after midnight in busy party areas, always lock your vehicle, and never leave passports or valuables visible. For scooters and motorcycles, a helmet is mandatory for both rider and passenger, and your IDP must cover the motorcycle category.

Frequently Asked Questions — Driving in Thailand
Everything you need to know about driving legally in Thailand — including Bangkok, Phuket, Chiang Mai, and Pattaya.
Do I need an International Driving Permit (IDP) to drive in Thailand?
Yes. Foreign visitors are required to carry an International Driving Permit (IDP) together with their original driver’s license. Thai police frequently request to see both documents during roadside checks or after traffic incidents. An IDP based on the 1949 Geneva Convention is accepted.
Can I drive in Thailand with a U.S., U.K., or Australian license?
Tourists from the U.S., U.K., Australia, Canada, and EU countries can drive in Thailand using their home-country license plus an IDP. Without an IDP, most car and motorbike rental agencies will refuse to rent to you, and police fines are common.
What side of the road does Thailand drive on?
Thailand drives on the left-hand side of the road, similar to the U.K. and Australia. Most vehicles have the steering wheel on the right. Always look both ways before crossing or turning, especially in busy areas.
What are the main driving rules and speed limits in Thailand?
Seatbelts are mandatory for front-seat passengers and helmets are required for all motorcycle riders. The alcohol limit is 0.05%. Speed limits are usually 60 km/h in cities, 90 km/h on rural roads, and 120 km/h on expressways. Random police checkpoints are common, especially at night.
What happens if I drive in Thailand without an IDP?
Driving without an IDP can result in a police fine of ₿500–₿1 000 (≈ USD 15–30). In the event of an accident, insurance companies may refuse coverage if you are not carrying a valid IDP, even if the fault is not yours.
