The typical color of a school bus in the United States is yellow. This distinctive hue, often referred to as "school bus yellow," was chosen for its visibility and safety. The color yellow is easily recognizable in various weather conditions, which enhances the safety of children getting on and off the bus. The decision to standardize this color was made in the 1930s, as it aimed to ensure that school buses could be seen from a distance. This initiative contributed to reducing accidents and keeping students safe while traveling to and from school.
