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 York State, residents are required to title and register their vehicles with the Department of Motor Vehicles (DMV). New residents must register their out-of-state vehicles within 30 days of establishing residency. The registration process typically involves providing proof of ownership, proof of identity, and payment of applicable fees. New York also mandates a safety inspection for all vehicles every 12 months, as well as an emissions inspection for gasoline-powered vehicles that are model year 1996 or newer and diesel-powered vehicles that are model year 1997 or newer. These inspections are required to be performed at DMV-licensed inspection stations. The emissions test is part of the New York Vehicle Inspection Program (NYVIP), and vehicles registered in the New York Metropolitan Area or the Upstate Area must undergo these inspections to help improve air quality in these densely populated regions.
