You’re Guaranteed a Ride Home!

Do you walk, bicycle, carpool, vanpool or take public transit to work, 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 to commuters who work in Contra Costa County and participants can use the program up to six (6) times in a calendar year.
