Vehicle inspection renewal in Sri Lanka

Written from published rules on 26 August 2026. Not monitored for changes since. A starting point, not official advice — confirm anything that matters with Department of Motor Traffic (DMT) (මෝටර් රථ දෙපාර්තමේන්තුව).

Renewing a vehicle inspection certificate in Sri Lanka primarily involves an emission test conducted by an authorized center, followed by adherence to requirements set by the Department of Motor Traffic (DMT). This is typically a mandatory step for annual vehicle licensing.

Your timing

It is generally advisable for vehicle owners to initiate the emission testing process a few weeks before their current vehicle license expires. This allows ample time to book an appointment, complete the test, and address any potential issues that might arise, such as a failed test requiring vehicle maintenance before retesting. Processing times for the emission certificate itself are usually quick, but unexpected delays or the need for repairs can extend the overall timeline.

Start 21 days ahead

To account for booking an appointment at an emission testing center, potential re-testing if the vehicle fails, and allowing sufficient time before the annual license renewal deadline.

The process

  1. 1Locate an authorized Vehicle Emission Testing (VET) center. These centers are operated by designated service providers.
  2. 2Schedule an appointment for the vehicle emission test, if required by the chosen center, or visit during operating hours.
  3. 3Take the vehicle to the VET center for the emission test.
  4. 4If the vehicle passes the emission test, obtain the Vehicle Emission Test Certificate. This certificate is often transmitted electronically to the Department of Motor Traffic system.
  5. 5Proceed with the annual vehicle license renewal process, which will utilize the emission test data.

What to bring

  • Vehicle Emission Test Certificate (issued after a successful test)
  • Vehicle's original Registration Certificate (or relevant details)
  • Previous year's Revenue License (for reference)
  • Proof of ownership (if required by the VET center or for license renewal)
  • Current insurance certificate (required for license renewal, not always for emission test itself)

The fee for the Vehicle Emission Test is a fixed amount, which may vary depending on the vehicle type (e.g., car, motorcycle, three-wheeler, heavy vehicle). These fees are typically paid directly at the authorized emission testing center. It is advisable to confirm the current fee with the chosen testing center or the DMT.

What commonly goes wrong

  • Ensure the vehicle is in good running condition before the test to avoid failing the emission standards, which would require repairs and re-testing.
  • Confirm the operating hours and any appointment requirements of the chosen emission testing center in advance.
  • Keep track of the Vehicle Emission Test Certificate, even if it's electronically submitted, as it serves as proof of compliance.
  • The emission test is a prerequisite for annual vehicle license renewal; ensure it is completed before the license expiry.
