Two from the bank, answered.

Real items, with the answer marked and the reason written out — the same format as all 80.

Loading & Unloading

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

  1. AThe interior aisle where students stand while boarding
  2. BThe 50-foot lane reserved for the bus at the curb
  3. COnly the space directly behind the rear bumper
  4. DThe area on all sides of the bus where children are in the most danger of being hitCorrect

Why: The danger zone is the area on all sides of the bus, extending as much as 30 feet from the front bumper and 10 feet on the other sides, where children are at the greatest risk of being struck. A driver may not be able to see students who are within this zone. Extra caution and mirror checks are essential before moving.

Emergency Evacuation

The most important consideration in deciding whether to evacuate the bus is:

  1. AWhether the radio is working
  2. BWhether staying on the bus or leaving it is safer for the studentsCorrect
  3. CHow close you are to the school
  4. DHow many students are aboard

Why: The key question in any emergency is whether the students are safer remaining on the bus or evacuating it. In many situations, staying seated on the bus is the safest choice. Evacuation itself carries risk, so it should be chosen only when remaining aboard is more dangerous.

Asked before starting.

Is your mock the same as the real CDL School Bus Endorsement?

No. Ours is 30 questions in 45 minutes; the real exam is 80 questions. Use the mock for stamina and section timing, not as a score predictor.
