HOT Lanes in the U.S.
There are six States that currently have high-occupancy toll (HOT) lanes. These lanes are similar to high-occupancy vehicle (HOV) lanes, except that they allow drivers of vehicles that do not meet the occupancy requirements to use the lane by paying a toll that varies by time of day or level of congestion. The San Diego FasTrak was the first HOT lane, opened in 1996. Tolls on the FasTrak vary from $0.50 to $4.00 on a typical day, but during peak periods can reach $8.00. The savings in travel time averages 20 minutes per journey.
