When a gate is coming down at a railroad crossing, the correct action is to stop when the lights begin to flash and the gate comes down. This is a critical safety measure designed to prevent accidents and ensure the safety of all road users. The flashing lights indicate that a train is approaching, and the lowering of the gate serves as a physical barrier to keep vehicles from entering the crossing while the train is present.

By following this procedure, drivers can ensure they are waiting for the train to pass before proceeding. This safety protocol is put in place to give ample warning to motorists and to prevent potentially catastrophic collisions with trains, which can take a considerable distance to stop. Stopping at the crossing when the lights flash is essential for maintaining safety at these potentially dangerous intersections.
