When approaching a bus displaying this sign on its rear that is stopped picking up passengers, you must:
A)Signal your presence with flashes of light.
B)Always stop behind the vehicle until it resumes its journey.
C)Reduce speed and, if necessary, stop the vehicle.Correct
Drivers are required to travel at a moderate speed and, if necessary, to stop when traffic, road, and visibility conditions demand it, and specifically when approaching a bus that is stopped, particularly if it is a school transport bus.
We should also remember that pedestrians have right of way when boarding or alighting from a bus at a designated stop, and are between the vehicle and the nearest pedestrian area or refuge.
