Emissions Waiver

  Traffic Line of Cars
  • Emissions Test Failure: When a vehicle fails the emission test, the owner needs to attempt to repair the vehicle.
  • Enhanced Area - 1968 and newer model gas powered vehicles: If the owner has spent $715.00 in emissions related repairs, the vehicle may qualify for a waiver.
  • Enhanced Area - 1967 and older gas powered vehicles: If the owner has spent $75 in emissions related repairs, the vehicle may qualify for a waiver. 

          

If the vehicle still does not pass the emissions test, Department of Revenue staff can work with the owner to issue a waiver when the car meets all waiver requirements. This waiver allows the owner to register the vehicle which gives the owner time to repair the vehicle to pass the emissions test and to drive the car for one testing cycle.

 

  • Missing or Tampered Emission Control Devices: Vehicles with missing or tampered emission control devices are not eligible for an emissions waiver. To knowingly operate a vehicle tampered or missing emission control systems or devices is in violation of state and federal law.

  • Fails for Smoke: Vehicles that fail for smoke are not eligible for an emissions waiver.
