HOV / HOT (Express) Lanes
METRO has an exciting option to make commuting easier. We’ve enhanced our High-occupancy Vehicle (HOV) Lanes to give people driving solo the option to pay a small toll to use the lanes, with High-occupancy Toll (HOT) Express Lanes.
HOV Lanes are restricted lanes reserved for vehicles with a driver and one or more passengers. Each vehicle that travels on an HOV Lane must carry at least two or, in some cases, three people. HOV Lanes allow drivers to travel faster and avoid congestion in regular lanes during peak periods. Motorcycles are permitted to travel on the HOV Lane at any time as per federal guidelines.
METRO converted the HOV Lane system to METRO HOT (Express) Lanes in order to make better use of an underutilized resource. During non-peak hours, single-occupant vehicles can access the HOV / HOT (Express) Lanes for a small toll.
