What condition must the reflective triangles meet?

• A. The reflective triangles must be damaged
• B. The reflective triangles must work properly and be secure
• C. The reflective triangles must be stored in the engine compartment
• D. The reflective triangles must be adjustable in size

Answer: (B)

The correct answer highlights that reflective triangles must work properly and be secure. This is essential for safety during roadside emergencies. These triangles are critical warning devices that help alert other drivers to the presence of a stopped or disabled vehicle, reducing the risk of accidents.

If the triangles are damaged, they would not serve their purpose effectively, and if they are not secure, they could be loose or fall over, failing to provide the necessary warning. Proper functionality and security ensure that they remain visible and effective under various conditions, thereby enhancing safety for both the bus and other road users.

The other choices propose conditions that either compromise safety—such as being damaged or improperly stored—or introduce features that are not standard requirements for reflective triangles, which are intended to be effective as signaling devices rather than adjustable objects or items that belong in the engine compartment.
