diamond lane
Shared-ride express path
A diamond lane is a traffic lane marked with diamond symbols, reserved for specific vehicles—typically carpools, buses, or other high-occupancy vehicles.
The designation encourages ride-sharing by giving qualifying vehicles faster passage through congested areas: We took the diamond lane and cut twenty minutes off our commute.
