Guaranteed Ride Home Program 

If you ever wonder how you would get home from work in case of a personal emergency or need to work overtime, Sun Rideshare offers a Guaranteed Ride Home (GRH) program, which allows up to four free taxi vouchers per year to registered Sun Rideshare participants. So, if you have a sick child on the day you carpool, or your boss asks you to work later than your bus pickup time, you have the added comfort of knowing you have a way to get home.

Who Can Use It

To qualify for GRH, you must carpool, vanpool, bike, ride the bus or walk to work at least twice a week. All participants must live in and work in Pima County. GRH vouchers can only be used to travel home or an emergency location like a hospital or child’s school from your workplace.  GRH vouchers cannot be used to travel to work.

Qualifying emergencies:

  • Personal or family illness
  • Personal or family emergency
  • Unexpected overtime
  • You are left without a ride because your carpool or vanpool driver had an emergency

How to Use It

The first step is to register with Sun Rideshare. Then click on “My Account” at the top of page and “sign up for GRH.” Once you are registered, a taxi voucher will be available as needed in the Sun Rideshare Travel Database. Login with your email address and password, click on GRH at the top of the page, and follow the instructions to print a voucher. Each registrant can use up to four vouchers every 12 months. A supervisor’s signature is required on all vouchers.
