Before entering a California carpool or HOV lane, what should a driver verify?
An elongated white outline diamond is painted in the left lane of an eastbound freeway. A solid white striped buffer separates it from the lane occupied by blue A.
Correct answer: That the vehicle qualifies under the posted rules and hours.
Why
Check the posted occupancy and operating hours, current vehicle eligibility, and permitted entry markings. California’s Clean Air Vehicle decal exemption ended September 30, 2025; an old decal no longer excuses a driver from occupancy rules. Meet any applicable toll requirements as well.
