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

Stop and wait for the signal to stop flashing.
Slow down and proceed with caution.
Speed up to clear the crossing quickly.
Stop only if a train is visible.

The correct answer is: Stop and wait for the signal to stop flashing.

A flashing red signal at a railway crossing indicates that a train is approaching. The best option is to come to a complete stop and wait until the signal stops flashing before proceeding. This ensures that you will not put yourself or others in danger by crossing the railway tracks while a train is passing through. Option B, slowing down and proceeding with caution, may not give enough time to stop if a train suddenly appears. Option C, speeding up, is dangerous and can cause accidents. Option D, stopping only if a train is visible, is not a safe choice as the train may only become visible when it is too late to stop. Therefore, the best course of action is to stop and wait for the signal to stop flashing before proceeding.
