Why should a driver use mirrors to check for pedestrians near the vehicle before closing the doors and departing from a stop?

Pick an answer

1. This check is required only at scheduled stops, not unscheduled ones, since unscheduled stops are assumed to be brief enough to skip the check
2. Mirror checks for pedestrians are relevant only in school zones
3. Pedestrians are never a concern once boarding has already begun
4. A pedestrian could be too close to the vehicle or attempting to board just as the doors are closing
