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.

​If you get stuck on the freeway because your automobile stops running, FSP can help. For example, FSP will:

• • Offer you a gallon of gas, if you run out.
  • "Jump start" your car if the battery is dead.
  • Refill your radiator and tape hoses.
  • Even change a flat tire.

 Note: The FSP program...

• Cannot tow your vehicle to a private repair service or residence.
• Does not recommend tow service companies, repair, or body shops.
• Does not tow motorcycles.
• Does not assist vehicles that have been involved in accidents, unless directed by CHP.
• Does report any accident to the CHP.

 If FSP cannot get your car going, it will be towed free of charge to a location approved by the CHP. The FSP will also contact additional assistance for you. The CHP will notify an auto club or towing service.


The Freeway Service Patrol (FSP) can be contacted from your mobile phone or using a freeway call box in the areas listed above by dialing 5-1-1.
