When is the driver required to cover the words "School Bus" on the vehicle?

The requirement to cover the words "School Bus" on the vehicle while transporting non-students is rooted in safety and clarity for both the driver and the public. When a school bus is transporting non-students, it is essential to avoid any potential confusion about its purpose. The visibility of "School Bus" can lead to misinterpretation by other drivers, who might then incorrectly assume that the vehicle is carrying children, potentially increasing the risk of incidents.

In contrast, there are specific scenarios outlined in regulations for when the markings are not required but they do not pertain directly to the safety concerns associated with transporting non-students. Covering the words helps to ensure that other drivers are not misled regarding the status of the bus and its current function on the road. This practice enhances road safety and promotes responsible driving behavior in proximity to the vehicle.
