Should you exercise extreme caution in this situation?

Why?

You are approaching a railway crossing with raised barriers and a B-20 STOP sign. You must take extra care when approaching and crossing the tracks, and check that no train is approaching. Raised barriers do not remove the need to look for trains or stop as required by the sign.
