SaferRide is the simplest possible way to get home safe and only has three self-explanatory buttons on the Home screen.
• Choose from a list of available taxi services in your area, and with the tap of a button call them.
• Call a pre-programmed contact.
• If you just need to know where you are, you can bring up a map of your current location.
SaferRide was developed by the U.S. Department of Transportation’s, National Highway Traffic Safety Administration (NHTSA).
