When can you turn on your hazard lights at a railroad crossing?

Answer: D — 200 feet

Turning on hazard lights at a railroad crossing is intended to alert other drivers and increase safety when you are approaching tracks where trains may be operating. The correct distance to activate your hazard lights is 200 feet. This allows ample time for the lights to signal to vehicles behind you that you are slowing down, stopping, or experiencing a potential hazard at the crossing. By giving this warning in advance, drivers can react safely and appropriately, reducing the risk of collisions at these critical points. Activating hazard lights at this distance enhances visibility and keeps everyone on the road safer, particularly in scenarios where a train might be approaching or when crossing gates are down.
