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 New Mexico, residents are required to title and register their vehicles with the Motor Vehicle Division (MVD). New residents must title and register their vehicles within 60 days of establishing residency. The state does not require a comprehensive safety inspection for vehicles. However, emissions testing is required for vehicles in Bernalillo County, which includes the city of Albuquerque. This is the only county in New Mexico that mandates emissions testing, and it is part of the Air Care program aimed at improving air quality. Vehicles that are 35 years old or older are exempt from this requirement. Additionally, new vehicles on their first and second registration, electric vehicles, and certain hybrid vehicles are also exempt from emissions testing.
