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 Jersey, residents are required to title and register their vehicles with the New Jersey Motor Vehicle Commission (MVC). New residents must title and register their vehicles within 60 days of moving to the state, or before their out-of-state registration expires, whichever is sooner. New Jersey does not require a state-wide vehicle safety inspection for private passenger vehicles, but it does mandate emissions inspections. Emissions testing is required every two years for most vehicles, except for new vehicles, which are given a five-year exemption. These inspections are aimed at maintaining air quality, and the requirement varies depending on the model year and type of vehicle. Vehicles registered in New Jersey may be required to pass an emissions test at a state inspection facility or a state-licensed private inspection facility.
