Which McDonald’s restaurant feature became a branding milestone when the first drive-through opened in 1975?

Drive-through service became a McDonald’s branding milestone when the first drive-through opened in 1975.

The first McDonald’s drive-through opened in Sierra Vista, Arizona, near Fort Huachuca. The location was designed to serve soldiers who could not leave their vehicles while wearing duty uniforms. Customers could order and collect food through a dedicated window rather than entering the restaurant.

Drive-through service strengthened McDonald’s identity as a fast, convenient restaurant. It also created a highly recognizable physical brand system: large roadside signs, menu boards, order speakers, pickup windows, and traffic lanes. These elements helped standardize the experience across thousands of locations.

The milestone is sometimes confused with modern curbside pickup or delivery. Drive-through service requires customers to order and receive food from a vehicle at the restaurant, while curbside pickup and delivery are later service models. The original 1975 opening was specifically a drive-through.
