12. Left-hand traffic
Left-hand traffic is a traffic system in which vehicles normally travel on the left side of the road. In countries using left-hand traffic, vehicles usually overtake on the right and most cars have the steering wheel on the right-hand side.
Drivers who are unfamiliar with left-hand traffic should pay particular attention at intersections, roundabouts, when turning and when entering or leaving roads, because familiar traffic movements are reversed compared with right-hand traffic.

Does traffic normally drive on the left in Thailand?
Yes. Traffic in Thailand normally keeps to the left on two-way roads. Drivers should take special care when arriving from a country that normally keeps right.
On which side is overtaking normally carried out in Thailand?
With ordinary left-hand traffic, overtaking is normally on the right. Exceptions can exist under local law, such as particular lane, turning or traffic conditions. Follow the local rules and never assume an unsafe pass is permitted.
What should visitors check when adapting to the driving side in Thailand?
Stay on the left after a turn, look carefully in both directions at crossings and roundabouts, and allow extra room when driving a vehicle with the steering wheel on the unfamiliar side. Observe lane arrows and signs.
