What should you do if you see a flashing red signal at a railroad crossing?

When you encounter a flashing red signal at a railroad crossing, the correct action is to stop and wait for the signal to change. A flashing red signal indicates that a train is approaching and it is unsafe to cross the tracks. Stopping ensures that you are not in the path of an oncoming train, which could lead to a serious accident.

The purpose of the signal is to provide a clear warning to drivers that they must yield to the train's right of way. After stopping, you should remain at a safe distance from the tracks until the lights stop flashing and it is confirmed that no train is coming. Following this rule is crucial for ensuring your safety and the safety of others on the road.
