Vehicle refueling services may be provided at self-service gas stations for motorists with disabilities if the vehicle displays an official state or locally issued disabled motorist plate or placard. Refueling services do not have to be provided when there is only one employee on duty, but is encouraged to do so, if feasible.
To receiving refueling services, you may be asked to honk your car horn twice and an employee on duty will pump gasoline for you. If there is not a posting regarding refueling gas service, you may have to go into the gas station or us an intercom if it is provided.
If you are pumping you own gasoline and the card reader is inaccessible to you, the employee on duty will turn on the pump remotely. After you have pumped your gasoline, you will need to enter the facility and pay the employee on duty.
