New Jersey emissions testing regulations

Some states limit emissions testing to certain counties—but New Jersey requires vehicles throughout the entire state to adhere to
emissions testing regulations
.
There are some exemptions, however. Let’s take a look at a few vehicles and situations so you can understand whether these regulations apply to you or not.

Which counties in New Jersey require emissions testing?

Location is not a determining factor for New Jersey’s emissions inspection program. Vehicles registered in every county in the Garden State are subject to the same emissions guidelines. 
Be aware that you might be subject to these regulations if you work or attend school in New Jersey, even if you don’t live there and your car isn’t registered there.

Which cars need emissions testing in New Jersey?

Since all New Jersey drivers are required to participate in emissions testing, the next factor we need to consider is the vehicle type.
Gasoline, diesel, and bi-fueled vehicles manufactured earlier than five years ago must pass emissions testing every two years if they have one of the following license plate types:
  • Passenger
  • Not-for-profit
  • Commuter vans
  • Governmental
Diesel vehicles made in 1997 or after and that weigh less than 8,500 pounds must also pass a smog check.
The New Jersey Motor Vehicle Commission (MVC) does not issue reminders. Check the inspection due date on the windshield sticker you received during your last inspection for more information.
You may also be required to take an emissions test as part of a
title transfer in New Jersey
.

Exemptions from New Jersey emissions testing

Some specific types of vehicles are exempt from New Jersey emissions testing. If you own and drive one of the following vehicles, you are exempt under current state law:
  • New vehicles not older than five years
  • Electric vehicles
  • Contractor equipment in transit
  • Farm vehicles
  • Historic and collector vehicles
  • Motorcycles and motorized bicycles
  • Vehicles operated by a county, city, fire district, or incorporated non-profit for first-aid, emergency, ambulance, rescue, or fire-fighting
  • Diesel vehicles made in 1996 model year or earlier (so long as they have passenger, not-for-profit, governmental, commuter van, farmer, or farm truck plates)
  • Diesel vehicles weighing between 8,501 and 17,999 pounds (so long as they have passenger, not-for-profit, governmental, commuter van, farmer, or farm truck plates)
Passenger vehicles and light-duty trucks (from 2009 model year and later) weighing less than 8,500 pounds must meet the California Low Emissions Vehicle Program standards. 
If the MCO (Manufacturer Certificate of Origin) does not have the above designation, the vehicle will require an exemption from the NJ Department of Environmental Protection (NJDEP) as well as a letter of approval to title the vehicle.

How does New Jersey emissions testing work?

Here are the basic steps for getting your vehicle emissions tested.
  • Locate a testing center. You can either choose a state-run facility (no fee) or find a
    Private Inspection Facility
    (fee-based). Call around to make sure you get a good price.
  • Go in for the inspection with your vehicle. The technician will run one of several tests, depending on the age and fuel type of your car.
  • Pay the fee and receive your results.

Types of emissions tests

The first step in an emissions test is to determine whether your vehicle is safe to drive. This usually includes a visual check of the instrument cluster and the gas cap
Next, your vehicle will undergo one of the following tests to measure its emissions:
  • OBD (On-board diagnostics) inspection, where the technician will use an OBD-II scanner to read trouble codes related to emissions problems
  • I/M 240 dynamometer inspection, aka the treadmill test
  • Two-speed idle test, where a probe is put into the exhaust pipe while the engine is revved 

What happens if you fail emissions testing in New Jersey?

If your vehicle fails emissions testing in New Jersey, you will receive a VIR (Vehicle Inspection Report). This is a second-chance document that allows you to re-test within a set time frame once repairs are made.
How do you know what repairs must be made? The inspection technician will provide you with an Emission Repair Form detailing the mechanical issues that need to be addressed. It’s like getting a cheat sheet to guarantee you pass the next test!
Don’t miss the 30-day grace period deadline. Otherwise, you could be charged late fees.
Unfortunately, New Jersey discontinued its waiver program in 2009.
