Driving on the Left
Thailand follows the British system of driving on the left. Be vigilant, especially at intersections and roundabouts.
International Driving Permit Required
To rent and especially to drive a vehicle in Thailand, you must have an International Driving Permit (IDP) in addition to your national driving license. And if it is a motorcycle or scooter (regardless of its power), you must hold a motorcycle license in your country of residence and have it mentioned on the international permit. So, make sure your international driving license is valid and covers the vehicle categories you wish to drive in Thailand. If you plan to roam around on a rental scooter, I invite you to read my article on
renting and driving a scooter in Thailand !The absence of an international permit or the appropriate license also results in the loss of your insurance coverage. Note that for Thailand, driving a scooter is often excluded from travel insurance contracts.
Helmet and Seatbelt Required
Wearing a helmet is mandatory for scooter and motorcycle drivers and passengers. And it is more than recommended given the high accident rate of two-wheelers on
the roads of Siam ! Fines for non-compliance with this rule are frequent, especially in tourist areas. There are even sometimes police checkpoints dedicated to scooters and motorcycles.
In cars, wearing a seatbelt is mandatory for all passengers. The fine for non-compliance is 2,000 THB. There is also a law, although rarely enforced, requiring children under 135 cm to be secured in a child seat.
Drinking and Driving in Thailand
In Thailand, the legal blood alcohol limit is 0.05% (or 0.02% for professional drivers and young drivers). Thailand strictly enforces this rule, and police checks are frequent, especially during the two major holiday weekends: New Year's Eve and Songkran in mid-April.
Speed Limits in Thailand
Speed limits vary by area. In cities, the speed limit is 50-60 km/h, on secondary roads 80-90 km/h, and on highways 100-110 km/h depending on the type of road. This applies to individual cars.
