Understanding inspections and the emissions test

What is the purpose of the emissions test?
Despite a variety of efforts to improve the quality of our air, New Jersey has yet to reach the level of air quality required by the National Clean Air Act standards that were set in 1990.

To help alleviate this problem, we need to repair the vehicles that exceed national health standards by routinely inspecting them at an inspection facility. You can find your vehicle's due date on the sticker on your windshield. Remember, you won't be reminded by MVC, it is your responsibility to schedule the inspection.

Note: BMW Series 7 owners must provide accessibility to the vehicle’s On-Board Diagnostic (OBD) computer by removing the cover plate prior to inspection. BMW dealers can complete this task. We apologize for any inconvenience this may cause.


The inspection process
Make sure you have all necessary documentation (driver license, registration, proof of insurance) with you – you won't pass the inspection without them.

• Vehicles may be inspected up to two months in advance of the due date
• Check your windshield sticker for inspection due date. Registrations and inspections do not necessarily match
• The inspector will determine your car's engine type and prep it for testing
• To pass a safety inspection, vehicles are expected to be maintained according to the original manufacturer’s specifications, including but not limited to: brakes, suspension, steering, wheel alignment, headlights, taillights, tires, horn, windshield wipers, window and hood operation, glazing, turn signals, mirrors, etc.
• The inspector will perform the appropriate emissions test based on the year, make and model of the vehicle
• The final stage of the test will assure that your gas cap is stable and limits the escape of fumes into the environment
• Upon completion, the inspector will place a new two-year sticker in your windshield

Low Emission Vehicle program
Effective January 1, all new 2009 model year and later passenger vehicles or light duty trucks weighing less than 8,500 lbs. are required to meet California Low Emission Vehicle Program standards. The Manufacturer's Certificate of Origin (MCO) must be marked California emission certified or USEPA 50 state emission certified. MCO’s marked Federal Emission certified or lacking designation require an exemption from the NJ Department of Environmental Protection (NJDEP). You can download a form to request exemption. An approval letter from NJDEP is required for vehicle titling.
