Renting cars and bikes: licence classes, big bikes, and the insurance trap

A rental shop handing you keys does not make you legal. To ride any rented motorcycle you need a motorcycle-category licence — a Thai one, or a home-country motorcycle licence recognised under section 42 bis of the Vehicle Act B.E. 2522 (1979) (usually via an IDP). A car licence covers cars only; riding on it is driving without a licence (s. 64: up to one month or 1,000 baht). For "big bikes" — motorcycles of 400cc or 35kW and up — Department of Land Transport rules under the Ministerial Regulation on driving-licence issuance B.E. 2563 (2020) additionally require certification from a DLT-approved training provider on top of the ordinary motorcycle licence.

What shops rarely explain is the insurance position. Only Por Ror Bor accident-victim cover is compulsory, and it pays injured people, not the bike or car. Whether the vehicle itself is covered depends on a voluntary policy the shop may or may not hold — and the OIC's standard motor policy (Registrar's Order 46/2567) excludes own-damage cover when the vehicle was driven by someone who has never held any driving licence, has been disqualified, or is using a motorcycle licence to drive a car; a separate exclusion voids it for alcohol over the 50mg/20mg limits. So an unlicensed or wrong-licensed renter typically pays for the crashed vehicle out of pocket, on top of fines and their own hospital bills — Por Ror Bor gives an at-fault driver only the initial damages tier. Check the actual policy, not the shop's verbal assurance, before signing.
