If the red lights begin to flash after you have started driving over the tracks, what should you do?

When the red lights begin to flash after you have started driving over the tracks, the appropriate action is to keep going to clear the crossing. This is because stopping on the tracks can lead to a dangerous situation, as trains can approach very quickly. If you are already committed to the crossing, the safest course of action is to continue driving at a steady pace to fully clear the tracks and avoid any potential collision.

In this scenario, reversing back to safety is not advisable since it could place the vehicle in a position of danger, potentially facing a train moving quickly from behind. Stopping immediately on the tracks is also hazardous, as it can result in a collision with an oncoming train, which could have fatal consequences. Additionally, waiting on the tracks until the lights stop flashing places the vehicle in an unsafe position and increases the risk of an accident. Therefore, maintaining momentum to clear the tracks is the best and safest action to take when red lights begin flashing after having already entered the crossing.
