Final answer:
A white diamond symbol on the pavement means that the lane is a High Occupancy Vehicle (HOV) lane.
Step-by-step explanation:
A white diamond symbol on the pavement means that the lane is a High Occupancy Vehicle (HOV) lane.
HOV lanes are designated lanes on highways or roads that are reserved for vehicles with a certain number of occupants. The white diamond symbol is used to indicate that only vehicles with multiple occupants are allowed to use that lane.
For example, a lane with a white diamond symbol may require that only vehicles with two or more occupants can use it, or it may be designated for vehicles with three or more occupants. These lanes help reduce traffic congestion and encourage carpooling.
