THE THAI DEPT OF TRANSPORT has a complete list of laws and requirements in Thai. This TA article is a pretty good summary.
Be advised that “conventions” still have to abide by these rules and are visa dependent. If you “ live” here YOU NEED A THAI LICENSE. If you are on a tourist visa you need both your home and intl license for the véhicule you are operating and after 60 days you need to apply for a Thai license. After 90 days you are no longer legal and can be held in the country until the incident is settled.
Stuart is right. I volunteer with the cops and have had a couple of sticky incidents where cars and motorcycles driven by unlicensed or over time limit foreigners.
The international license is to give cops a chance to understand licences in multiple foreign languages. The 90 day limit is for TOURISTS and to make sure that longer stay drivers are put through the Thai health and reaction tests. Supposed to watch the video too. Enforced 100%? NO. But don’t have an accident involving bodily harm or you might end up meeting me through iron bars. Lol
Yup same for Canada. If divorced u need a copy of decree. If single I guess just swear. The embassy web site is quick to respond for info and appointment.
Oh also please be aware that a “car” Thai license DOES NOT allow you to ride a motorcycle or scooter. You would also need a motorcycle license for that.
