You approach a railroad crossing. Its red lights begin to flash and its bells ring, but no gate is down and you cannot see a train yet. What must you do?
A approaches a railroad crossing with a crossbuck and flashing red warning light. No gate is down and no train is visible; the card states that the crossing bells are ringing.
Correct answer: Stop 15 to 50 feet from the nearest rail, and stay stopped while the lights flash.
Why
Crossing signals start before the train arrives, and a train can be closer and faster than it looks. The 15-foot minimum keeps your vehicle clear of the train, which is wider than the rails. At a crossing with more than one track, a second train can come from the other direction after the first one passes, so check again before you go.
