The Department of Motor Vehicles (DMV) is a government agency responsible for managing vehicle registration and driver licensing in a specific state or region. It ensures that drivers meet safety and legal requirements, and it maintains records of vehicle ownership and driving history. In addition to issuing driver's licenses and vehicle registrations, the DMV also conducts driving tests and provides information on traffic laws. The agency plays a crucial role in promoting road safety and ensuring that all drivers are qualified to operate vehicles on public roads.
