What is a key safety feature of a school bus?

The bright color and stop sign arm serve as crucial safety features for a school bus. The vibrant yellow color is specifically chosen for school buses because it is highly visible to other drivers, especially in various lighting conditions, making it easier to spot on the road. This visibility is essential for ensuring that other road users are aware of the bus, particularly when it is picking up or dropping off children.

The stop sign arm, which extends from the side of the bus when the vehicle is stopped, is a significant safety mechanism. It alerts other drivers that they must stop, as children may be entering or exiting the bus. This feature is designed to create a safe environment for students, who might be crossing the street as they board or leave the bus. Together, these features enhance the overall safety of the school bus, making it a protected environment for children.
