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 Alaska, residents are required to title and register their vehicles with the Division of Motor Vehicles (DMV). New residents must title and register their vehicles within 30 days of establishing residency. Alaska does not have a statewide vehicle safety inspection program, so vehicles are not required to pass a comprehensive safety inspection for registration purposes. However, certain commercial vehicles may be subject to safety inspections. Additionally, Alaska does not have an emissions testing program, as the state does not require emissions tests for vehicles to be registered, regardless of the county of residence. This is due in part to the less densely populated nature of the state and different air quality issues compared to more urbanized states.
