A bus at a stop begins indicating on a 50 km/h road. At the same time, a pedestrian steps out from in front of the bus. What should an A1 rider prioritize?

1. Slow or stop, giving way to the bus and protecting the pedestrian hazard
2. Overtake immediately before the bus moves
3. Focus only on the bus signal because pedestrians must wait
4. Sound the horn and continue at the posted speed
