Accelerate moderately as you pass the testing van. Moderate acceleration is required to produce the most representative sample of your vehicle’s exhaust emissions. Therefore, deceleration or heavy acceleration may result in an invalid reading.

Change of Ownership

Used vehicles that are for sale are required to have a new emissions inspection, even if the current inspection report still has time on it. However, there is an EXCEPTION to this rule:

  • If a newer used vehicle is sold and there are 365 days or more left on the original seven (7)-year exemption, the vehicle does not require a new inspection at the time of sale.

It is the seller's responsibility to obtain the inspection. This is a consumer protection for the buyer. The seller must provide the emissions inspection paperwork to the buyer for vehicle registration purposes. The buyer must use this paperwork to register the vehicle within one year.  A vehicle dealer may offer customers a voucher enabling the buyer to obtain an inspection for free. The customer has the right to refuse this arrangement.

If you purchased a vehicle from a dealer and used a dealer voucher to obtain an inspection, and the vehicle failed the test, access our Dealer Information.
