A red traffic light is just beyond a railroad crossing, and there is not enough space for the whole school bus plus 15 feet beyond the tracks. What should the driver do?

1. Wait before the tracks until there is enough storage area to completely clear them
2. Pull forward until the front half of the bus clears the tracks
3. Stop with the rear axle on the tracks and wait for the traffic light
4. Ask students to get out and walk across the crossing
