The Guaranteed Ride Home program (GRH) at CU provides a free taxi ride home in the event of an emergency or work schedule change. (Limited to CU Boulder and CU System EcoPass holders and CU Boulder vanpool members).

GRH is a great solution for those who avoid taking the bus, carpooling or biking because they worry about what would they would do in case of a family emergency.  It is also perfect for those who use alternative transportation and have an unforeseen emergency arise. 

How to Book Your Ride

  • Give them the CU Boulder account or authorization number BOU5302 to approve your request.
  • You may also need to give them the 16-digit number off your Buff One card, so have that available.
  • Tell them where you are to be picked up and your destination.
