Discover key driving rules in Thailand, license requirements, and the essentials of renting a vehicle in Phuket—travel safely!

Which Licenses Are Required for Driving in Thailand

If you plan to drive a car or scooter in Thailand, you must have an International Driving Permit (IDP) along with a valid driver’s license from your home country. Local police are authorized to check both documents.

Important points about driving licenses:

Thailand has signed but not ratified the Vienna Convention on Road Traffic. As a result, your national driver’s license is not considered valid without an accompanying IDP.
To operate a scooter with an engine of 125cc or more, you need a license with a motorcycle category (A/A1). While rental shops may sometimes overlook this, you risk a 500–2,000 THB fine if stopped by the authorities.
If you stay in Thailand for more than six months, it’s advisable to obtain a local Thai driver’s license.

Key Traffic Rules and Driving Conditions in Thailand

Left-Hand Traffic

Thailand follows left-hand traffic, which can feel unfamiliar. Start on quieter roads to get comfortable with driving on the left.
Flashing Headlights

Unlike many countries where flashing headlights means “go ahead,” in Thailand it often means “I am not letting you pass—move aside.” Stay alert!
Speed Limits
- In towns and cities: up to 60 km/h (about 37 mph)
- Outside urban areas: up to 90 km/h (about 56 mph)
- On highways: up to 120 km/h (about 75 mph)
Major Roads Don’t Always Have Priority

Even on main roads, drivers may cross intersections without slowing down or looking. Be cautious, especially near side streets.
Give Way to the Left

Because of left-hand traffic, the “yield to the left” rule applies. In practice, however, local drivers often sort things out through situational negotiation.
Unofficial ‘Rules’
- Larger vehicles often assume priority. Buses and trucks can drive aggressively—when in doubt, let them go first.
- Drivers typically focus only on what’s ahead, so sudden stops or turns without warning are common.
Unreliable Turn Signals

Thai drivers may fail to use turn signals, forget to switch them off, or use hand signals instead. Don’t rely on indicators—rely on your own judgment.
Flashing Red Light at Intersections

A flashing red light means you may turn left if it’s safe and after yielding to other vehicles. Watch for signs that may limit this rule.
