Road safety reality
Road accidents are the **single biggest danger** to visitors in Thailand, which has one of the world's highest road-fatality rates. Motorbike/scooter crashes injure large numbers of tourists every year, often inexperienced riders without proper licences or helmets on unfamiliar, hilly or wet island roads — Koh Samui's ring road included. If you ride: wear a helmet (it's the law and your insurance may depend on it), hold the correct licence, never ride drunk, and go slowly. As a pedestrian, assume traffic won't stop for you. Cross with care and don't assume right of way at crossings.
⚠ Verify live
