Fear of being stranded in an emergency prevents some employee commuters from participating in a ridesharing arrangement. One of the most commonly cited reasons for not ridesharing is concern about being stranded at work in the event of illness, accident or emergency. Employers can offer a Guaranteed Ride Home (GRH) program for eligible commuters who rideshare or commute to work. This voucher program provides a free taxi cab ride home from work in case of emergency on a day that an employee uses a commute alternative. There are many no cost Gauranteed Ride Home programs offered throughout the U.S. to employers who promote the use of commute alternatives & sustainable transportation.
