What does “carpool lane” mean
The dominant California name for what the federal government and most other states call an HOV lane: a restricted freeway lane reserved for vehicles with two or more occupants, marked with a white diamond on the pavement. Caltrans officially preferred carpool over HOV in signage for roughly 50 years, so the term locked in for everyone who learned to drive in the state. Sometimes also called the diamond lane.
