Inspection / Maintenance (I/M) Program

For Station Owners & Inspectors For Analyzer Vendors

Beginning Wednesday, April 1, 2015, emissions tests are not required for vehicles in the three most recent model years if they have less than 70,000 miles on their odometers. However, annual safety-only inspections are still required for all cars and trucks in North Carolina. Go to the "3-year calculator" page for additional information.

Inspection / Maintenance

The Inspection/Maintenance (I/M) Program for cars and trucks makes sure that the air pollution controls are working properly on vehicles. This is important because motor vehicles contribute substantially to air quality problems.

Emissions Testing

North Carolina requires emission systems tests for cars and light-duty trucks as part of the annual safety inspection in 48 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.
