The reason why school buses are typically yellow is primarily due to safety concerns. The bright, vibrant yellow color enhances visibility and makes it easier for other drivers on the road to see the bus, especially in low light conditions or bad weather.

To understand why school buses are yellow, we need to look into the history of school bus safety. In the 1930s, a professor named Dr. Frank Cyr organized a conference to address the various safety concerns related to school buses. During this conference, the attendees came up with the idea of using a specific color to make school buses more noticeable.

After extensive research and testing, it was determined that yellow is the most visible color from a distance, especially when combined with black lettering. The use of this highly visible color helps to reduce the risk of accidents by making it easier for drivers to spot a school bus and take necessary precautions on the road.

So, to answer your question, school buses are yellow primarily for safety reasons. This color provides a prominent visual cue to other drivers, ensuring that they can easily recognize and respond to the presence of a school bus on the road.
