Which vehicles are required to pass the test?

If you own a passenger car or light-duty truck in the Drive Clean program area, it will have to pass a Drive Clean test every two years prior to renewing the sticker on the licence plate. This applies to vehicles that are more than three model years old and less than 20 model years old. You will be notified up to 90 days before the expiry of your vehicle licence plate. As well, the test applies at change of ownership. If your vehicle is older than the current model year and less than 20 model years old, and if the ownership change requires a safety certificate, it must also pass a Drive Clean test.

Motorhomes also require testing every two years. Vehicles 20 model years or older, light-duty commercial farm vehicles and motorcycles are exempt.

Testing at registration will alternate between odd-year models and even-year models. For example, in 2002, odd model-year vehicles will be tested.

In 2003, even model-year vehicles will be tested.
