A 1939 conference gave American school buses their deep yellow

Georgia’s Albert Luce built his metal bus for cement workers first

A 1939 conference of transportation officials from all 48 U.S. states set the deep, slightly orange-tinted yellow that has defined American school buses for decades, choosing the shade for its visibility. The decision counts among the earliest school-bus safety standards adopted in the United States, the Associated Press reported.

The color came not from Congress but from a consensus among state transportation officials. The 1939 delegates selected it as a visibility rule, not as a binding federal mandate, and the slightly orange hue has since become the national shorthand “school bus yellow” for the deep, glossy finish that distinguishes the American school bus.

The metal-bodied bus itself took shape in rural Georgia, where car dealer Albert Luce designed the vehicle to haul cement workers. When the company turned the design down, Luce marketed it to school districts, the AP reported.

The pivot landed in the middle of a consolidation of American education. As districts replaced one-room neighborhood schoolhouses with larger campuses much farther apart, the AP called the timing “impeccable.” That consolidation, the AP reported, gave rise to the school bus.

At the system’s peak in the 1980s, more than 60% of U.S. students rode the yellow buses to school each day, the AP reported.
