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.
Q7When properly adjusted, the outside convex mirrors on a school bus allow the driver to see which area that flat mirrors cannot adequately cover?
Show answer
✓ Correct answer: The blind spot area along the sides and rear corners of the bus
Convex mirrors provide a wide-angle, panoramic view of the sides and rear corners, filling in the blind spots that straight flat mirrors cannot adequately cover due to their limited field of view.
Q8A student exiting the bus crosses to the right side of the road and then realizes she forgot something on the bus. She turns back and runs toward the bus. As the driver, what is your first priority?
Show answer
✓ Correct answer: Signal the student with your hand to stop and do not move the bus
The CDL manual instructs drivers to use a hand signal to stop the student and hold the bus in place until the student is safely clear of all danger zones, because movement of the bus while a student is in a danger zone is one of the most dangerous situations.
Q9Which statement correctly describes a properly adjusted crossover mirror image on a school bus?
Show answer
✓ Correct answer: It shows the entire front bumper area and both sides of the bus out to the front danger zone
A correctly adjusted crossover mirror displays the entire front bumper, both sides of the bus up to the side mirrors, and the ground in front of the bus, allowing the driver to spot students in the front danger zone.
Q10A school bus is stopped for loading on a two-lane road. In your flat mirror you can see a student standing 8 feet from the left rear corner of the bus. Which of the following correctly describes that student's status relative to the danger zone?
Show answer
✓ Correct answer: The student is inside the danger zone because she is within 10 feet of the bus
The 10-foot danger zone surrounds all sides of the bus including the rear; any person within 10 feet of any exterior surface is inside the danger zone regardless of which side they are on, and the driver must not move until that student is clear.
