Which of the following is true about railroad crossings?

You must stop for an approaching train, a closed gate, or a red flashing signal at a railroad crossing. You cannot drive around a partially lowered gate. If you have stopped for a train, you should not proceed immediately after the train has passed. Wait until you have a decent view of the tracks as there may be another train coming.
