Car & motorbike insurance in Thailand: the compulsory minimum and the cover that actually protects you

Two layers, two vehicles, one common mistake

Vehicle insurance in Thailand always comes in two parts, and conflating them is the classic newcomer error — on a motorbike most of all. The first part is compulsory third-party insurance (CTPL), called por ror bor (พ.ร.บ.), required by law on every registered bike and car and renewed each year with the road tax. The second is voluntary insurance — the policy you choose to add, in tiers called Class 1, 2, 3 and the popular 2+ and 3+. The compulsory layer is a thin legal formality; the voluntary layer is what actually pays to repair vehicles and shield you financially. The catch with bikes is that the compulsory layer is so cheap that many riders stop there and assume they are covered. They are not.

The shared foundation: CTPL + the voluntary classes

The framework is identical for both vehicles. CTPL (por ror bor) is bought once a year, tied to the registration renewal, and covers bodily injury to people only — nothing for any vehicle or property — up to modest statutory limits. On top sit the voluntary classes, from fullest to thinnest cover:

For the full breakdown of the classes on the car side — including the som hang (dealer repair) versus som oo (general garage) terms and the survey-slip claims process — see our dedicated car insurance in Thailand guide. The rest of this page concentrates on the motorbike.

Motorbike insurance: where it differs

A bike is not just a small car for insurance purposes. The economics and the risks shift:

• CTPL is very cheap — often only a few hundred baht a year, so there is no excuse to let it lapse; you cannot tax the bike without it.
• Voluntary cover is cheap too — and often skipped — because a scooter is worth little, riders reason they would not repair it. Fair enough for the bike, but it ignores your liability to others and your own injury.
• Liability is the real exposure — clip an expensive car and the repair bill can be many times the bike’s value. Even on a cheap scooter, voluntary third-party liability is worth pricing.
• Theft matters — bikes are far easier to steal than cars; if you want theft cover, you need a class that includes it (1, 2+ or 2), not bare third-party.
• Rider injury — motorbike accidents are a leading cause of serious injury here; lean on your health insurance and a correctly endorsed travel policy, not the bike’s CTPL alone.

Car vs motorbike: a side-by-side

What it costs (illustrative)

Numbers move with the vehicle and insurer, so treat these as orientation, not quotes:

• Motorbike CTPL — roughly a few hundred baht a year.
• Motorbike voluntary cover — modest; comprehensive-style cover on a scooter is typically a small fraction of a car’s premium, and third-party-only is cheaper still.
• Car CTPL — roughly 600–1,200 baht a year.
• Car Class 1 — commonly ~10,000–20,000+ baht a year, scaling with value and repair terms.

How foreigners buy & pay

Buying as a foreigner is straightforward; the vehicle’s paperwork matters more than your nationality.

• If you own it — buy CTPL and any voluntary class in your own name through insurers, brokers, banks or online comparison sites, using the registration book (blue book for a car, green book for a motorbike) and your passport.
• If you rent or lease — the operator usually arranges CTPL and any voluntary cover, but you must confirm what is included, the excess, and whether you are a named, licensed driver. Thin rental cover is a common trap.
• Paying — many insurers allow monthly installments rather than one up-front premium.
• Match the details — named drivers, sum insured and repair terms must reflect real use; mismatches are where claims get refused.

The licence trap that voids claims

This is the single most expensive mistake riders make. A motorbike requires a motorcycle licence — a car licence, or a car-only international driving permit, does not authorise you to ride a bike. If you crash without the correct category, an insurer or a travel or health policy can reduce or refuse the claim, and you can face fines at a police checkpoint. The fix is simple: ride only with the right licence. See getting a Thai driver’s licence for how to convert or test, and make sure your travel and health cover explicitly include motorbikes — many exclude them by default.

At the scene: the accident protocol

What you do in the first few minutes protects both your safety and your claim — and on a bike, your safety comes first because riders are exposed:

• Safety first — check for injuries; call 1669 for medical emergencies and 191 for police if anyone is hurt or fault is disputed.
• Call your insurer’s 24-hour hotline — the number is on your policy card; save it before you ever need it.
• Do not move the vehicles in a dispute — the positions are the evidence; wait for the surveyor or police if fault is contested.
• Photograph everything — positions, damage, plates, and the other party’s licence and insurance details.
• Stay calm, don’t admit fault — let the surveyors and, if needed, the police establish liability.

The claim then revolves around the insurer’s surveyor and the claim slip they issue authorising repairs — the same process described in full in the car insurance guide.
