Some Traffic Rules for Driving in Thailand
Once you have successfully received your license, which usually happens on the day of your application, you should be aware of the following traffic rules:
You must be at least 18 to drive.
Legal limit BAC is 0.5 mg per 1 liter of alcohol
Drive on the left-hand side as in the UK
Seatbelts are mandatory in front seats only, child car seats are optional
(Motorcyclists must wear helmets)
The speed limits range as follows:
50 – 60 km/h in suburban streets
90 – 120 km/h on highways
Keep in mind that due to the high volume of traffic on Thai streets, the average speed will be determined by the general flow of the traffic, not a sign (that is if you see one).
Carry your vehicle registration and driver’s license on you at all times.
