What action should be taken at a railroad crossing when warning lights are flashing?

When warning lights are flashing at a railroad crossing, it indicates that a train is approaching and that it is not safe to cross the tracks. The appropriate action is to stop before the tracks and wait until the lights stop flashing. This precaution is in place to ensure the safety of all road users, as trains can travel at high speeds and may not always be visible until they are very close.

Continuing to cross the tracks while the lights are flashing puts you at significant risk of a collision, which is why stopping is mandatory. It's also important to remember that the lights signal potential danger and erring on the side of caution protects both the driver and passengers in the vehicle, as well as anyone else in the vicinity.

Other options may suggest actions that could lead to hazardous situations. For example, speeding up to cross quickly disregards safety protocols, and proceeding with caution as usual when warning lights are active underestimates the potential danger. Looking for oncoming trains is not sufficient, as the flashing lights are an explicit signal that a train is or will be approaching and signify that all crossings should be treated with vigilance.
