California Vehicle Code 21655.5(b) prohibits driving in a High-Occupancy Vehicle (HOV) lane — commonly called a carpool lane — in violation of posted requirements. HOV lanes typically require two or more occupants, though some lanes allow qualified clean air vehicles with a DMV-issued decal. Despite being a non-point infraction, the fine for an HOV violation is among the highest for non-point citations in California, typically reaching $490 or more after assessments.
The Department of Transportation and local authorities, with respect to highways under their respective jurisdictions, may designate preferential use of highway lanes for high-occupancy vehicles. The designation shall be made by appropriate signs and markings on the highway.
(b)
It is a violation of this section for a person to drive a vehicle in a high-occupancy vehicle lane in violation of the instructions imparted by the official traffic control devices designating the lane.

Frequently Asked Questions
Common questions drivers search for after receiving this citation.
California Vehicle Code 21655.5(b) prohibits driving in a designated High-Occupancy Vehicle (HOV) lane in violation of the posted rules. HOV lanes are marked with diamond symbols and signs specifying occupancy requirements — typically 2+ or 3+ persons. Driving solo in a 2+ lane is the most common violation.

Yes, with limitations. Vehicles with a valid California DMV-issued Clean Air Vehicle (CAV) decal may access HOV lanes regardless of occupancy, but only while the decal program is active and the decal has not expired. Expired decals do not provide HOV lane access. The officer may check decal validity at the stop.
Yes. Common defenses include showing that the vehicle had sufficient occupants, presenting a valid unexpired CAV decal, arguing that posted signage was unclear or missing, or challenging the officer's observation.
