Do I need a helmet on a rented scooter?
Category A is the other thread. This one is the plastic on your head. Shops still hand you a cracked half-shell.
Rider and passenger
| Rule people actually meet | Source shape (as of 30 Aug 2026) |
|---|---|
| Helmet on the head, not on the hook | RTP “Safe Roads” campaign from 1 June 2025; Chiang Rai Times (updated Jul 2026) quotes officers on Land Traffic Act s.122 |
| Fine | Reported up to 2,000 THB per person without a helmet. Older 500 THB tables still circulate. Believe the ticket, not the hostel poster |
| Passenger | Fined too. Two people, two heads |
| Rental “free helmet” | Often junk. Buy a real one if you are riding more than a soi |
This is not legal advice. Enforcement is patchy and then suddenly a checkpoint. The expensive part is still the crash, not the ticket. Licence class is the other safety thread: “Can I ride a scooter on a car licence in Thailand?” — Category A, not this plastic.
If you will not wear one, do not rent. Grab exists.
