McDonald’s opened its first drive-through window in 1975 at a restaurant near Fort Huachuca in Sierra Vista, Arizona.
The restaurant served military personnel who could not leave their vehicles while wearing fatigues. McDonald’s adapted the location by adding a service window, allowing customers to order and receive food without entering the dining room.
This innovation became an important part of McDonald’s brand identity because it connected the company’s promise of speed with automobile convenience. Drive-through service later became a standard feature at many McDonald’s restaurants and a highly recognizable part of the chain’s operating model.
The opening is sometimes confused with the introduction of McDonald’s other convenience features, such as its early walk-up service and later digital ordering systems. The specific milestone here is the first McDonald’s drive-through window, which dates to 1975 and occurred in Sierra Vista, Arizona.
