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 Rhode Island, residents are required to title and register their vehicles with the Rhode Island Division of Motor Vehicles (DMV). New residents must title and register their vehicles within 30 days of establishing residency. Rhode Island does not require a state-wide safety inspection for vehicle registration. However, the state mandates that vehicles undergo an emissions test every 2 years. The emissions testing program is designed to improve air quality and applies to gasoline-powered cars and trucks that are 2 to 24 years old. Exemptions are provided for new vehicles for the first 2 years after their model year and for vehicles 25 years or older. The emissions testing is required in all counties of Rhode Island, ensuring that air quality standards are maintained throughout the state.
