Emissions Testing

North Carolina requires emission systems tests for cars and light-duty trucks as part of the annual safety inspection in 19 counties. Vehicles from 1996 and newer are usually equipped with On-Board Diagnostic (OBD) systems, which help inspectors check that the vehicle's pollution controls are working.
