What should a motorcycle rider do when approaching an intersection where a school bus is stopped with its red lights flashing?

1. Stop completely, regardless of which direction you are traveling, unless separated by a median barrier.
2. Slow down and proceed with caution at a speed under 15 km/h.
3. Proceed without stopping if you are traveling in the opposite direction on a two-lane road.
4. Squeeze past the bus on the shoulder to avoid delaying traffic.
