About 511 SF Bay and its coverage

The program is led by the Metropolitan Transportation Commission (MTC), California Highway Patrol and Caltrans. Its nine-county service area covers Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano and Sonoma. The website and phone service operate around the clock. This listing specifically describes the Bay Area program; other states and regions run their own 511 services.

  • Road travel: Interactive map, traffic alerts, critical advisories and incident information.
  • Travel planning: Driving-time and traffic-condition information through the voice phone service.
  • Other transportation: Transit information, bridges, express lanes, carpooling, vanpooling, biking and walking resources.
  • Roadside assistance: The Freeway Assist program routes requests for help; the Freeway Service Patrol has a separate administrative contact.
  • Data services: Official traffic and transit open-data resources for developers and transportation organizations.

Freeway assistance and contractor directory

For non-emergency freeway assistance, call 511 and say “Freeway Assist.” Call 911 for an emergency, including a vehicle stalled in a travel lane. The program’s published contractor contacts are Atlas Towing Services (415-673-4242), B&A Bodyworks/Towing (415-822-4887), Bob’s Tow (408-866-7777), Roadrunner Tow (707-434-9560), and Yarbrough Bros. Towing (707-584-5000). These administrative listings do not establish heavy-truck recovery capability, eligibility or a free commercial-truck tow. Confirm the appropriate assistance for your vehicle with the answering center.

How company drivers can use this resource

  1. Check the map and alerts while safely parked before departure.
  2. Compare the affected highway and travel direction against your dispatch route and delivery appointment.
  3. Confirm any alternate road’s commercial-vehicle restrictions, height, weight and access limits with the responsible road authority.
  4. Check with the receiver for entrance directions and staging instructions; a traffic map does not establish legal truck parking.
  5. Contact your fleet’s roadside-assistance provider when specialized truck recovery is needed.

511 information can support trip planning, but current signs, closures and official instructions control road access. Travel times are estimates rather than guaranteed arrival times.
