The California Department of Motor Vehicles (DMV) is the state agency that registers motor vehicles and boats and issues driver licenses in the U.S. state of California. It regulates new car dealers (through the New Motor Vehicle Board), commercial cargo carriers, private driving schools, and private traffic schools. The DMV works with the superior courts of California to promptly record convictions against driver licenses and subsequently suspends or revokes licenses when a driver accumulates excessive convictions (as measured by a point-based system). It issues California license plates and driver's licenses. The DMV also issues identification cards to people who request one.
