What is PRB?
PRB stands for the Compulsory Motor Insurance Act (Por Ror Bor) — sometimes called CMI. It is the basic motor insurance every car in Thailand must carry by law, providing baseline protection for anyone injured in a motor accident — driver, passengers, or third parties. PRB is different from voluntary insurance (Class 1, 2+, 3+). Premiums are fixed by regulation and coverage is strictly for bodily injury and death. It does not cover damage to your own vehicle.
Why every car needs PRB
- Required by law. Driving without PRB carries a fine of up to THB 10,000.
- Required to renew annual car tax — no PRB means no tax sticker.
- Provides initial medical coverage to injured parties without waiting to prove fault.
- Helps cover medical bills and compensation for everyone affected by an accident.
What PRB covers
PRB provides baseline protection without needing to prove fault first, plus compensation after fault is determined. Coverage amounts are set by regulation.
- Medical expenses for injured parties, paid as billed up to the statutory cap
- Compensation for death or permanent disability of injured parties
- Daily compensation while hospitalised
- Covers driver, passengers, and third parties affected by the vehicle
Coverage limits and details follow current OIC regulations and the latest law.
What PRB does NOT cover
Many people assume PRB works like Class 1 or Class 2+ insurance, but PRB only provides basic protection. PRB does not cover:
- Damage to your own car — whether collision, single-vehicle accident, flood, or fire
- Damage to the other party's vehicle or other people's property
- Theft or loss of the vehicle
- Medical or compensation costs above the statutory PRB cap
- Damage from driving while intoxicated or without a valid licence
How PRB relates to car tax renewal
PRB is a required document for renewing annual car tax. Without a valid PRB, you cannot renew tax. The Department of Land Transport's system checks for an active PRB before accepting tax payment. So renewing PRB first is the necessary first step. Many drivers handle PRB and car tax together, often alongside reviewing their voluntary insurance for the same period — fewer trips, less risk of forgetting either expiry.
