If a Pennsylvania school bus is stalled on railroad tracks and no train is in sight, what safe-location guidance does PennDOT give?

1. Evacuate students to a safe place at least 200 feet away from the bus and do not cross the tracks
2. Keep students seated on the bus until a train is visible
3. Move students exactly 10 feet from the bus and wait on the ballast
4. Send students across the tracks to stop traffic
