1. When making a stop to pick up students, a driver should ensure all surrounding traffic has stopped before:
  1. Opening the door and signaling for the students to approach. ✓
  2. Turning on the alternating red lights.
  3. Pulling over to the side of the road.

Answer: A. Opening the door and signaling for the students to approach.

The driver should make sure all surrounding traffic has stopped before opening the door and signaling the students to approach. The handbook tells school bus drivers to make a final check that all traffic has stopped before completely opening the door and signaling students to approach. That places the traffic check right before the door opens and before students are given the signal to come toward the bus. It connects directly to the action of letting students approach, so the driver does not invite them forward until surrounding traffic is stopped.
