On-Board Diagnostic (OBD) Emissions Inspection
North Carolina is fighting ozone-forming emissions from gasoline-operated cars and light duty trucks. Inspections are conducted using the vehicle's on-board diagnostic (OBD) system, computerized equipment installed on all new vehicles since 1996.
The following types of vehicles do not need an OBD emissions inspection:
- Model 1995 vehicles, or older
- Diesel-operated vehicles
- Vehicles licensed under the farmer rate
- Vehicles not registered in an emissions county
