Guaranteed Ride Home

You’re Guaranteed a Ride Home!

Do you walk, bicycle, carpool, vanpool, or take public transit to work or college, but worry about being stranded during an emergency? 511 Contra Costa’s Guaranteed Ride Home (GRH) program alleviates this problem by providing “commuter insurance” for alternative commuters who need a ride home due to unexpected circumstances.

The program is free if one of the following applies to you:

  • You commute to work in Contra Costa County
  • You are a resident of Contra Costa County and your regular, daily commute to work is in a county or location that does not have a Guaranteed Ride Home program (such as Santa Clara County).
  • You go to college in Contra Costa County at one of the following schools:
    • CSU Eastbay (Concord Campus)
    • Contra Costa College
    • Diablo Valley College Pleasant Hill
    • Diablo Valley College San Ramon
    • Los Medanos College
    • Saint Mary’s College

Participants can use the program up to six (6) times in a calendar year. See details below.
