HOV Lane Diamond Symbol

White diamond painted in the lane reserves it for high-occupancy vehicles during posted hours.

A large white diamond symbol painted on the pavement marks a preferential lane reserved for high-occupancy vehicles (HOV), typically carpools, vanpools, buses, and in some states motorcycles or clean-fuel vehicles. Solo drivers may not use the lane during posted hours. Always read the accompanying sign for the minimum number of occupants and the times of day the restriction applies.
