Freeway Service Patrol

FSP Tow Truck 

​The Freeway Service Patrol (FSP) is a joint program provided by the California Department of Transportation (Caltrans), the California Highway Patrol (CHP) and the local transportation agency. The FSP program is a free service of privately owned tow trucks that patrol designated routes on congested urban California freeways. Typically, FSP operates Monday through Friday during peak commute hours, and all day in pre-designated freeway construction zones. In heavily congested freeway corridors it is becoming more commonplace for FSP to operate during the midday and on weekends/holidays in addition to the weekday peak period service.

FSP Service TruckThe goal of the FSP is to maximize the effectiveness of the freeway transportation system. The FSP is a congestion management tool which strategically addresses commute traffic pattern problems. Deployment of the FSP trucks is driven by congestion patterns in major metropolitan areas. It is necessary for the FSP program to respond immediately to changing or increasing needs for impediment mitigation.

The goal is accomplished by the expeditious removal of disabled/stranded vehicles from the freeway. Removing obstructions on the freeways as rapidly as possible has a positive impact on traffic volumes by eliminating problems which contribute to non-recurrent congestion. Each year, the FSP program assists approximately 650,000 motorists on California's highway system.
Rapid removal of freeway obstructions also reduces fuel consumption and minimizes automobile emissions by reducing the time vehicles spend idling in stopped traffic. Currently, over 350 tow trucks operated by CHP-trained, certified and supervised drivers, patrol in excess of 1,750 miles of the most congested freeways in California.

The combined statewide operation directly assists more than 650,000 stranded motorists per year. </p>
How much does the Freeway Service Patrol (FSP) program cost?How much does the Freeway Service Patrol (FSP) program cost?<p>​​The FSP provides service to motorists at no cost. All costs of operating the FSP program are provided through state and local public funding allocations. State funding is apportioned to each FSP program through a funding formula based upon population, miles of freeway in the region, and a measurement of congestion. The local transportation agencies match the state funding allocation with a minimum of 25 percent of local funds.</p>
What is Freeway Service Patrol?What is Freeway Service Patrol?<p>​​The CHP, Caltrans, and local transportation agencies joined forces to provide emergency roadside services during commute periods. The goal of the program is to remove impediments to traffic to expedite the flow of traffic. </p>
What other benefits are derived by the Freeway Service Patrol (FSP) program?What other benefits are derived by the Freeway Service Patrol (FSP) program?<p>​​During recent years, the responsibilities of CHP officers increased significantly and are continuing to expand. In those metropolitan regions of the state where FSP is deployed, FSP tow truck drivers are a cost-effective complement to many of the motorist services that are provided by the CHP beat officer. Due to the structure of FSP beats, the FSP tow truck driver is frequently the first to arrive on the scene of freeway incidents. As such, the FSP tow truck driver provides valuable "real time" information about the incident to the CHP Communications Center.</p>
