Decal for High Occupancy Vehicle (HOV) lane exemption (DMV)

The Clean Air Vehicle (CAV) decal program is administered by the Department of Motor Vehicles (DMV) in partnership with the California Air Resources Board (CARB). The program authorizes a vehicle that meets specified emissions standards to be issued a CAV decal to allow single occupancy use of High Occupancy Vehicle (HOV or carpool) lanes. CARB establishes the official list of eligible vehicles based upon vehicle emissions.
