What is required to be covered when operating a SPAB for non-students?

When operating a School Pupil Activity Bus (SPAB) for non-students, it is essential to have the appropriate markings and signals to ensure safety and compliance with regulations. The inclusion of red amber lamps and a school bus sign is crucial because these features alert other road users that the vehicle is designated to transport children.

The school bus sign indicates that the vehicle is functioning in a capacity that could include transporting minors, prompting other drivers to exercise additional caution. The red amber lamps serve a similar purpose, providing a visual cue that the bus might stop or is in the vicinity of students, reinforcing the need for careful driving in the surrounding area.

The other options provided do not fully encapsulate the requirements for operating a SPAB for non-students, as they focus on different aspects of bus operation that do not specifically pertain to the safety measures demanded during the transport of minors. Thus, having both red amber lamps and a school bus sign is vital for signaling the purpose of the vehicle and ensuring the safety of all road users.
