Starting November 1, 2008, North Carolina vehicle safety and emissions inspections will go electronic.
This means that windshield inspection stickers will no longer be issued at your next inspection on or after November 1. After that date, the vehicle's inspection will become due the same month as the vehicle's registration renewal as shown on your license tag sticker.
Beginning November 1, vehicles will be required to pass a vehicle inspection prior to registration renewal by the North Carolina Division of Motor Vehicles.
The North Carolina General Assembly passed legislation (N.C. General Statute Chapter 20, Article 3A, Part 1) requiring the move to electronic inspection authorization to increase inspection compliance statewide and to further benefit the state's air quality and highway safety.
