What are HOT lanes?
High occupancy toll (HOT) lanes are HOV lanes (for carpools of two or more, vanpools and buses) that are also open to solo drivers who pay a toll. Toll rates adjust electronically to ensure that traffic in the HOT lane is free flowing (at least 45 miles per hour 90 percent of the time) even when the regular lanes are congested. The SR 167 HOT lanes provide toll-free express trips for buses, vanpools and carpools of two or more, and also give solo drivers the option to pay for a faster, more reliable trip when they need it the most.
