What action is prohibited at a railroad crossing?

The action that is prohibited at a railroad crossing is passing a vehicle while the lights are flashing. When the warning lights are activated at a railroad crossing, this indicates that a train is approaching. It is essential for drivers to heed these signals and stop, ensuring they do not endanger themselves or others by attempting to overtake another vehicle. The flashing lights serve as a critical safety mechanism designed to prevent accidents by warning drivers of the imminent approach of a train.

Other actions, such as waiting for a train to pass, checking for trains before crossing, and yielding to pedestrians, are generally acceptable and necessary for safe navigation at crossings. Waiting for a train to pass is expected behavior, while checking for trains is a vital precaution. Yielding to pedestrians aligns with traffic laws that prioritize pedestrian safety, especially in areas where they may be crossing close to the tracks. Thus, the focus on not passing while lights are flashing is crucial for maintaining safety at railroad crossings.
