When the lights are flashing at a crossbuck, what is the appropriate action?

When the lights are flashing at a crossbuck, it signifies that a train is approaching, and immediate action is required for safety. Stopping and waiting until it is safe to cross ensures that you are not in harm's way. Trains can approach quickly and cannot stop easily, so it's crucial to heed the warning. This action allows you to assess whether it is safe before proceeding, as approaching trains often cannot be heard until they are very close, sometimes due to other environmental sounds or distractions.

Crossing immediately or at a reduced speed can put you in a dangerous situation if a train is indeed approaching. Signaling other drivers to go is also inappropriate, as each driver must rely on their judgment regarding the safety of crossing, which is best determined by patiently waiting for the signal to clear. Following the flashing lights' warning can help prevent accidents and saves lives.
