Carpool /High Occupancy Vehicles (HOV) Lanes
A carpool lane is a special freeway lane used only for carpools, buses, motorcycles, or decaled low-emission vehicles. You may use a carpool lane or on-ramp if your vehicle carries the posted minimum number of people required for the carpool lane, or you drive a low-emission vehicle displaying a special DMV-issued decal. Motorcycle riders may use designated carpool lanes, unless otherwise posted.
Signs at the on-ramp or along the freeway tell you the minimum number of people per vehicle required for the carpool lane(s). These signs also list the days of the week and the hours when the carpool requirement applies. The pavement in this lane is marked with a diamond symbol ◊ and the words "Carpool Lane."
These lanes are also known as highoccupancy vehicle (HOV) lanes. Do not cross over double parallel solid lines to enter or exit any carpool lane except at designated entry or exit places.
