Heavy-Duty Vehicles

 

Drive Clean requires large trucks and buses to pass regular emissions tests in order to have their registrations renewed. This applies to heavy-duty diesel-powered vehicles registered anywhere in Ontario and to heavy-duty non-diesel vehicles in the areas of southern Ontario where light-duty testing is required.

Heavy-duty vehicles are required to undergo emissions testing every year. Effective September 1, 2011, vehicles will need a test for registration renewal at seven years of age, instead of five. As a consumer-protection measure, an emissions test pass is required for an ownership transfer for vehicles with a model year older than the current calendar year.

In 2005, we introduced an incentive that encourages good vehicle maintenance by giving heavy-duty diesel vehicles operators the opportunity to have their vehicle tested every two years, instead of annually.
