What color are all school buses primarily painted?

• A. Orange Yellow
• B. Florescent Yellow
• C. National School Bus Yellow
• D. School Bus Green

Answer: (C)

The primary color of all school buses is known as National School Bus Yellow. This specific shade was established in the early 1930s and is widely recognized for its high visibility and safety attributes. It is a color that is not only distinct but also easily visible in various weather conditions, making it an ideal choice for vehicles that transport children. This standardization helps ensure that school buses are immediately identifiable on the road, which enhances safety for both the children being transported and other drivers.

The other options, while related to the colors of some buses, do not represent the standardized color used across the country for school buses. Many might confuse fluorescent variations or different terms used regionally, but National School Bus Yellow is the required hue recognized in regulations and guidelines for school bus manufacturing and operation. This ensures consistency and safety in transport for students nationwide.
