What should you do if you approach a railroad crossing with lights flashing?

Answer: C — Stop and wait until the lights stop flashing and it is safe to cross

When approaching a railroad crossing with lights flashing, it is imperative to stop and wait until the lights stop flashing and it is safe to cross. The flashing lights indicate that a train is approaching the crossing, and this warning is there to ensure your safety. Trains can travel at high speeds and it can be difficult to judge their distance, so stopping is the safest course of action. Ignoring the warning and continuing to drive or trying to speed up puts you at significant risk of a collision with the train. Additionally, honking your horn does not improve safety in this situation; in fact, it could distract both you and other drivers from the critical task of observing the oncoming train. Therefore, the correct response to flashing lights at a railroad crossing is to stop and ensure the track is clear before proceeding.
