Law and Compliance

In October 2003, the Government of Sri Lanka, through the Department of Motor Traffic (DMT) called request for proposals for the Sri Lanka Vehicle Emissions Test (SLVET) program. The program identifies vehicles which exceed applicable emission standards and places them through a repair and certification process.

Testing and Certification is mandatory and is tied to the issuance of a vehicle’s Annual Revenue License. Click below to download a PDF copy of the gazette notification outlining emission standards.
