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 Massachusetts, residents are required to title and register their vehicles with the Massachusetts Registry of Motor Vehicles (RMV). New residents must register their vehicles within 30 days of becoming a Massachusetts resident. The state mandates that all vehicles undergo a safety inspection within seven days of registration. Additionally, Massachusetts requires vehicles to pass an annual emissions test as part of its commitment to improving air quality. This emissions test is required for all vehicles registered in the state, not just those in more densely populated counties. Failure to comply with these requirements can result in fines and other penalties.
