What is the role of hazard lights when stopping at an RR crossing?

The role of hazard lights when stopping at a railroad crossing is to warn other drivers of the stop. When a bus approaches a railroad crossing, activating the hazard lights serves as a signal to other vehicles that the bus has stopped and that they should also be cautious and prepared to stop if necessary. This is particularly important at railroad crossings where visibility may be limited and the potential for an oncoming train poses a significant safety concern. The use of hazard lights effectively communicates to surrounding traffic that the bus is stationary and that they should be mindful of the situation, enhancing safety for everyone involved.

Other options, such as indicating a bus malfunction, signaling students to cross, or alerting passengers of a delay, do not accurately reflect the specific function of hazard lights in this context. Hazard lights are intended to increase awareness of the bus's status on the road, especially at critical points like railroad crossings where additional caution is required.
