Smog Check and Car Inspection in New Jersey

Summary: New Jersey Emissions Inspection Program

The New Jersey Motor Vehicle Commission (MVC) requires most vehicles to undergo an emissions inspection upon vehicle registration and again every 2 years. Although the safety portion of testing has been eliminated in general, some vehicles still require safety inspections. Vehicles that fail must be repaired and retested within the time allotted on their Vehicle Inspection Report. Initially, new residents have different emissions inspection requirements.

New Residents to New Jersey

Once you move to New Jersey, you must have your vehicle inspected within 14 days of registration, unless it is listed as exempt.

Note that you don't have to transfer your registration until either of the following happens first:

  • 60 days have passed since you moved to New Jersey.
  • Your out-of-state registration expires.

See Completing a NJ Vehicle Inspection below for more information.

Out-of-State Extensions

Your vehicle is not subject to an emissions inspection until it returns to New Jersey unless the vehicle will be out of the state for an extended period of time AND the vehicle is located in a state which has an enhanced emission inspection program.

For more information on vehicles located out-of-state, please contact the MVC at (609) 633-9474 or (609) 633-9460.

Failed Vehicle Inspections

You must have your vehicle repaired and retested within the time allotted on the Vehicle Inspection Report.

In addition to the Vehicle Inspection Report, your inspector will give you an Emission Repair Form. This document also details your vehicle's problems and helps the repair technician make the necessary repairs.

The MVC allows you to have your vehicle repaired at a state-approved Emission Repair Facility (ERF) or to make the repairs yourself.
