What is the 'danger zone' around a school bus?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

The area on all sides of the bus where children are in the most danger of being hit, extending up to about 10 feet in front, 10 feet on each side, and behind the bus, including the area where the driver's view is limited

  1. A The interior aisle of the bus
  2. B The area only directly behind the bus
  3. C The area on all sides of the bus where children are in the most danger of being hit, extending up to about 10 feet in front, 10 feet on each side, and behind the bus, including the area where the driver's view is limited
  4. D Only the loading door

Why this is the answer

The danger zone is the area immediately around the school bus where students are at greatest risk of being struck, either by the bus itself or by passing traffic, and where the driver's direct vision is limited. It extends roughly 10 feet in front of the bus, 10 feet on each side, and the area behind the bus, plus any space the driver cannot see directly and must view using the mirrors. Children are taught to stay out of the danger zone and to remain where the driver can see them. The driver must account for these blind areas before moving, because a child who drops something near the bus may be invisible from the driver's seat.
