Scooter and motorbike accident risk on Koh Samui

This is the most important safety topic for most Koh Samui visitors, stated plainly and without exaggeration: the realistic danger to tourists on the island is not crime, it is the road. The World Health Organization estimates Thailand's road traffic death rate at about 25 per 100,000 people, among the highest in Asia, and motorcyclists account for the large majority of road deaths (sources cite roughly 74-84%). Multiple governments, including the UK Foreign Office, identify motorcycles and scooters as one of the greatest dangers facing their citizens in Thailand, and emergency rooms in tourist areas treat foreign motorbike accident cases every day. Typical injuries are road rash, broken bones, and head and facial injuries. The risk factors stack up quickly for visitors: many have never ridden a motorbike before; traffic drives on the left; island roads have sand patches, potholes, unmarked speed bumps, stray dogs, and steep winding sections such as the hill between Chaweng and Lamai; and rain makes everything slippery. Alcohol is involved in a large share of tourist crashes. Rental shops will often hand a scooter to anyone with cash, but that does not make it legal or safe, and riding without the correct licence can void your insurance (see the licence and insurance records in this category). If you do not ride at home, the honest advice is not to learn on Samui's roads. Taxis, songthaews, ride-hailing apps and rental cars are all available alternatives.

Summary

Motorbike accidents are the single biggest cause of tourist injury in Thailand, and Koh Samui is no exception. Unfamiliar roads, left-hand traffic, sand on corners, rain, and riders with no experience or licence all contribute. Understand the risk honestly before deciding to rent a scooter.
