Vehicle Emission Testing (VET)

Law and Compliance

In the year 2003, The Department of Motor Traffic called out for a tender in order to initiate the Vehicle Emission Testing (VET) Project in Sri Lanka. The VET 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.
