Fun Fact: The 'No Traffic Lights' Claim

A popular claim in travel writing and by long-time expats is that Koh Samui has no traffic lights at all. This was historically accurate: the island's entire road system grew around the one ring road with simple junctions and roundabouts. Today the claim is outdated - at least a few traffic lights operate, for example at the Maenam village junction and at busy Chaweng intersections, and traffic jams are now a normal part of high-season life. But compared with any Thai city, lights are still rare, and most junctions on the 50+ km ring road are uncontrolled. Treat 'no traffic lights' as a charming exaggeration that tells you something real: how recently Samui was a roadless island, and how fast it has changed.
