What is essential to check on side rear marker lights?

• A. They can be cracked but working
• B. They must be secure and operational
• C. They can be replaced with tape
• D. They should be dimly lit

Answer: (B)

The correct choice emphasizes the importance of the side rear marker lights being both secure and operational for safety and compliance with traffic regulations. Side rear marker lights serve to enhance visibility, particularly during low-light conditions or poor weather, and indicate the vehicle's width to other drivers. If these lights are loose or malfunctioning, it could lead to safety hazards such as other vehicles misjudging the size or position of the bus, thereby increasing the risk of accidents. Ensuring that these lights are secure prevents them from being easily damaged or falling off while the bus is in operation. Furthermore, if a marker light is not functioning properly, it must be addressed immediately to maintain compliance with regulations and ensure the safety of the bus and its passengers.
