What is the correct procedure for a student who encounters a railroad crossing with flashing lights?

1. Speed up to cross the tracks before the train arrives at the crossing — active railroad crossings require stopping at least 15 feet from the nearest rail.
2. Stop at least 15 feet from the nearest rail, wait until lights stop flashing and gates rise, then proceed
3. Stop on the tracks to look both ways for approaching trains
4. Honk and drive around lowered gates if no train is visible
