Most states have titling and registration laws that require residents to title and register their cars in the state—and for new residents of the state to do so within some period of time, such as 30 days. Some states require titled cars to pass a comprehensive safety inspection. And some states also require cars owned by residents of certain counties to pass an emissions test/inspection designed to improve air quality in more densely populated counties.
In North Carolina, residents are required to title and register their vehicles with the North Carolina Division of Motor Vehicles (NCDMV). New residents must title and register their vehicles within 30 days of establishing residency. The state mandates that most vehicles undergo a safety inspection annually, which must be completed within 90 days of renewing the vehicle's registration. Additionally, vehicles registered in certain counties are required to pass an emissions inspection as part of the annual safety inspection. These counties are typically more densely populated and the emissions test is aimed at improving air quality. Failure to comply with these requirements can result in penalties, including fines and the inability to renew the vehicle's registration.
