Q1The danger zone immediately surrounding a school bus is defined as the area extending how far from every side of the bus?
Show answer
✓ Correct answer: 10 feet from every side
The FMCSA/AAMVA CDL manual defines the danger zone as the area within 10 feet of the school bus on all sides, where children are at greatest risk of being struck because the driver's visibility is most limited.
Q2When students must cross the road in front of a stopped school bus, they should walk to a point at least how far ahead of the front bumper before crossing?
Show answer
✓ Correct answer: 10 feet ahead of the front bumper
Students are instructed to walk forward until they can see the driver's face and are at least 10 feet ahead of the front bumper, placing them outside the front danger zone and in the driver's field of view before crossing.
Q3Which mirror type is mounted at the front corners of a school bus and is primarily used to monitor the danger zone directly in front of and to the sides of the bus?
Show answer
✓ Correct answer: Crossover mirrors
Crossover (cross-view) mirrors are mounted on the front corners of the bus and give the driver a wide-angle view of the area directly in front of and to both sides of the front bumper, which is otherwise a blind zone.
Q4Outside left and right flat mirrors on a school bus should be adjusted so that the driver can see which of the following?
Show answer
✓ Correct answer: 200 feet or four bus lengths to the rear along each side
Per CDL manual guidance, outside flat mirrors must be adjusted to show at least 200 feet (approximately four bus lengths) to the rear along each side of the bus so the driver can monitor traffic and students near the sides.
Q5The extended danger zone in front of a school bus — the area where an approaching driver might not stop in time — can reach up to how far ahead of the front bumper?
Show answer
✓ Correct answer: 30 feet
The CDL manual notes that the danger zone in front of the bus can extend up to 30 feet, because oncoming or passing vehicle drivers may not stop quickly enough to avoid a child who steps out from in front of the stopped bus.
Q6A school bus driver has just activated the loading zone. Before closing the door and moving, the driver should account for every student who boarded or alighted by doing what?
Show answer
✓ Correct answer: Counting all students who got on or off and confirming none remain in the danger zone
The CDL manual requires drivers to count every student who boards or exits and visually confirm through mirrors that no student is still in any danger zone before moving the bus.
