Report Out-of-State Registration Violators
The State of California loses millions of dollars of revenue every year from California residents who neglect to register their vehicles in California. California residents with vehicles registered outside of the state don’t contribute to the upkeep of the freeways and bridges they use. The Officers and senior volunteers within the California Highway Patrol Registration Enforcement and Guidance (CHP REG) Program are dedicated to assisting the public with California registration compliance.
A California resident, for purposes of vehicle registration, is any person who manifests an intent to live or be located in this State on more than a temporary or transient basis. California law permits only 20 days to complete the process of registering your vehicle.
