New Jersey State Emissions

In 1990, the National Clean Air Act Standards were put in place. However, since that time the state of New Jersey has not been able to reach the level of air quality that is required by these standards.

In order to help with this issue, vehicles need to be repaired when they do not meet national health standards. In order to determine if they meet the standards, vehicles need to be inspected at a facility routinely. The due date for your inspection will be listed on the sticker that you display on your windshield. Keep in mind, that you will not be reminded of this schedule so it is important that you keep up with the expiration date.

Inspection process

When you are undergoing the inspection process you will need to bring in all the necessary documentation that is required including your driver’s license, registration and proof of insurance. It is also acceptable to bring in a photocopy, fax, email or online registration receipt this well.

Your vehicle may be inspected up to two months before the due date. It is important to realize that your registration expiration does not necessarily match your inspection. The inspector will first determine your vehicle’s engine type and prep it for testing. After it has been prepped an emission tests will be performed depending on the year make and model of the vehicle.

The final stage of this testing process is to make sure that the gas is stable and that fumes are not able to escape into the environment. After your inspection has been completed, the inspector will replace your old sticker with a new two-year sticker for your windshield.

Used vehicles

If you purchase a used, noncommercial vehicle, regardless of if you buy it in or out of New Jersey, you are not required to obtain an inspection until the vehicle is at least five model years old.

If you do purchase one of these vehicles, you will receive a decal that will be valid until the last day of the month registration, five years from the vehicle’s model year. You will also receive a form SS – 19 at the time of registration.

In order to inspect this vehicle you will need to bring form SS – 192 to a state operated inspection station along with a registration card, insurance ID card, and driver’s license. New-car dealers will also be allowed to issue new vehicle stickers that are less than five years old.


There are also some types of motor vehicles that are required to have an annual inspection in the state of New Jersey. These are taxis, limousines, buses, gas or by fueled vehicles and diesels that are less than 10,000 pounds. You can learn more about this rule online or through the DMV.
