Scooter & motorbike rental (legal and safety notes)

Summary

Renting a scooter is the most popular way to explore Koh Samui, but it is only legal with the right licence: a home-country motorcycle licence plus an International Driving Permit with the motorcycle category. Riding without them risks fines and invalid insurance.

Details

Typical costs

Indicative 2026 rental prices from island rental listings: about 150-350 THB per day for a 110-125cc automatic scooter, 250-450 THB for larger 150-160cc models, with discounts for weekly/monthly rental. Prices vary by shop and season - these are examples, not quotes.

Licence law

Thai law requires a motorcycle licence for any scooter, whatever the engine size. Foreign visitors need: (1) a valid home-country licence WITH a motorcycle category, and (2) an International Driving Permit (IDP) showing the motorcycle endorsement (Thailand recognises IDPs under both the 1949 Geneva and 1968 Vienna conventions; the IDP must be a physical booklet and obtained in your home country before travel). A car licence - even with an IDP - does NOT cover scooters. Police checkpoints on Samui (including near Chaweng and the airport) do check documents.

Insurance risk

Riding without the correct licence/IDP can void your travel insurance after an accident. Check that your policy covers riding a scooter of the engine size you rent, as a driver, in Thailand.

Helmets

Helmets are legally required for driver and passenger, with fines up to 2,000 THB reported. Check the rental helmet fits and is undamaged.

Deposit advice

Common traveler advice: photograph the bike's existing scratches with the agent present, and avoid leaving your passport as deposit - offer cash or a photocopy instead.

Local tips

• Get the IDP in your home country before you fly - you cannot get one in Thailand.
• The ring road is mostly flat and paved, but the hills between Chaweng and Lamai and the steep, sandy south-west roads (Route 4170) need real caution, especially when wet.
• Samui's rainy season is roughly October to December; painted lines and bends become slippery fast.
• Fuel is cheap and sold at stations and roadside bottles; a full ring-road loop uses well under a tank.

Safety

• Never ride without a helmet, correct licence and IDP - checkpoints enforce all three.
• Do not ride after drinking; insurance and law both treat this severely.
• Inexperienced riders should not learn on Samui's hill sections; consider a car instead.
• Avoid riding at night on unlit stretches and avoid the south-west coastal road in rain.
