Vehicle Roadworthiness in Thailand

All cars over seven years old and motorbikes over five years old must undergo regular inspection by official test centres. Find out where and how to get a car tested…

Cars older than seven years and motorbikes older than five years need to undergo a safety inspection every year in order to be issued with a document called a TorRorOr, which certifies that the vehicle is roadworthy. No reminder is issued, but without the TorRorOr it is not possible to get the annual tax sticker once the car is over seven years old.

Note: All cars must display a tax sticker on the windscreen as proof that car tax has been paid. The ticket has an expiry date. Car tax is paid annually at the local DLT office.


The local Department of Land Transport Office (DLT) does not issue the TorRorOr, but there are many private companies around Thailand that are authorised to perform this service. These companies can be identified by their official logo: a yellow gear on a blue circle.

The test includes an emissions test, an engine check and a general roadworthiness test. It will include work on:

  • Lights
  • Indicators
  • Brakes
  • Steering
  • Tyres
  • Bodywork

Vehicles will also be checked to ensure that the chassis number, engine numbers and colour are identical to those in the Registration Book (Blue Book or Lem Tabian).

Car owners should take their Blue Book to the test, and motorbike owners should take their Green Book.

Passing the test

Once the car has successfully passed the roadworthiness test, the certificate (TorRorOr) will be issued. This allows the owner to obtain their annual tax sticker. The TorRorOr is handed over to the DLT when getting the tax sticker.

The annual tax rates are calculated by the age and type of the car, as well as its engine size. For vehicles up to five years old, the price is fixed against these variables. After five years, the tax will fall by 10 percent every year, up to a maximum of 50 percent.

Failing the test

If the vehicle fails the test, the owner must make repairs until the vehicle is able to pass it.

The DLT will not issue a tax sticker for a vehicle over seven years old if it does not have a TorRorOr certificate. It is illegal to drive a vehicle without an up-to-date tax sticker in Thailand, and anyone found doing so is liable to pay a fine. Late payment of tax will result in a fine of one percent of the fee every month.
