Road Charge Projects

California’s Road Charge Pilot

In an effort to ensure California’s transportation funding system can keep up with changing technology and modes of transportation, in 2014, the California State Legislature passed Senate Bill 1077 (DeSaulnier) which established a road charge pilot study that would test the feasibility of funding road and highway repairs based on how many miles a driver travels instead of how much gas they purchase.

California’s Road Charge Pilot Program launched on July 1, 2016 and ran for nine months. During that time, more than 5,000 vehicles from all over the state reported over 37 million miles driven, through six different reporting and recording methods ranging from manual methods to highly technical methods with optional location‐based services.
