Changes to the Clean Vehicle Program:
As of September 30, 2019, hybrid vehicles are no longer eligible for the Clean Vehicle Program.
The UDOT Express Lanes are intended to maximize freeway efficiency by encouraging carpools. Single-occupant vehicles are allowed to fill any remaining capacity by paying a toll. By federal law, states may allow energy-efficient vehicles with single occupants to use the lane at a reduced toll. UDOT has allowed a limited number of vehicles to receive Clean Vehicle Permits, allowing them free and unlimited access to the Express Lanes. The federal statute defines two categories of low emission and energy-efficient vehicles to be eligible for the toll exemption. The exemption for gasoline-powered hybrid vehicles expired on September 29, 2019. Plug-in hybrids, electric vehicles, and alternative-fuel vehicles are currently eligible for an exemption through September 29, 2025.
Express Lanes Suspended in Construction Zones:
Obey all signing and striping in the free and suspended locations!
All single-occupant vehicles can use Express Lanes southbound between 600 North and Lehi Main Street and northbound between Lehi Main Street and Point of the Mountain. This is a result of the I-15 Southbound and the I-15 Technology Corridor projects. Please visit those sites for more information.
Utah's Express Lanes, located on I-15 between Layton and Spanish Fork, provide all commuters with more consistent speeds and fewer slowdowns along I-15 when used correctly. The express Lanes help reduce traffic congestion for drivers in all lanes and ensure all I-15 lanes can carry their maximum capacity.
The Express Lanes can be used by carpooler, buses, motorcycles, emergency vehicles and C Decal vehicles (these vehicles are the priority in the Express Lanes and may continue to use them without charge). Solo drivers with an Express Pass may fill any remaining space for a fee.
Violation of Utah's Express Lanes (also known as high-occupancy vehicle lanes, or HOV) causes unnecessary slowdowns and congestion. To maximize the efficiency of the Express Lanes and the entire I-15 corridor, follow the rules
