A.As much as 10 feet
B.As much as 30 feet, with the first 10 feet the most dangerous
C.As much as 50 feet, with the first 15 feet the most dangerous
D.As much as 100 feet
Explanation: Section 10.1.1 says the danger zones may extend as much as 30 feet from the front bumper, with the first 10 feet being the most dangerous. The zones also extend 10 feet from each side and 10 feet behind the rear bumper.
2How far does the danger zone extend from the left and right sides of a school bus, according to the Alaska CDL Manual?
A.5 feet
B.15 feet
C.20 feet
D.10 feet
Explanation: Section 10.1.1 describes danger zones extending 10 feet from the left and right sides of the bus and 10 feet behind the rear bumper. The area to the left of the bus is always considered dangerous because of passing cars.
3Why does the Alaska CDL Manual say the area to the left of a school bus is always considered dangerous?
A.Because of passing cars
B.Because the fuel tank is on that side
C.Because the service door is on that side
D.Because the crossover mirrors cannot see it
Explanation: Section 10.1.1 says that in addition to the 10-foot side and rear zones and the front zone, the area to the left of the bus is always considered dangerous because of passing cars. Students crossing the road must pass through it.
4When properly adjusted, what should the outside flat mirrors let the driver see behind the bus?
A.50 feet or 1 bus length
B.100 feet or 2 bus lengths
C.200 feet or 4 bus lengths
D.400 feet or 8 bus lengths
Explanation: Section 10.1.3 says the flat mirrors should be adjusted so you can see 200 feet or 4 bus lengths behind the bus, along the sides of the bus, and the rear tires touching the ground.
5According to the Alaska CDL Manual, how far can the blind spot directly behind a school bus extend?
A.No more than 10 feet
B.About 25 feet
C.Exactly 100 feet
D.50 to 150 feet, and up to 400 feet depending on bus size
Explanation: Section 10.1.3 says the blind spot behind the bus extends 50 to 150 feet and could extend up to 400 feet, depending on the length and width of the bus. That is one reason backing a school bus is strongly discouraged.

Explanation: Section 10.1.4 says to position the convex mirrors to see the entire side of the bus up to the mirror mounts, the front of the rear tires touching the ground, and at least one traffic lane on either side. These mirrors do not accurately show size and distance.

A.Traffic in the lane next to the bus, out to 200 feet
B.The rear emergency door and the last row of seats
C.The roof hatches and the top clearance lights
D.The area in front, from the bumper at ground level
Explanation: Section 10.1.5 says crossover mirrors should show the entire area in front of the bus from the front bumper at ground level to a point where direct vision is possible, and direct vision and mirror view should overlap. They should also show both front tires touching the ground and the area from the front of the bus to the service door.
10How should the overhead inside rearview mirror be positioned, according to the Alaska CDL Manual?

B.The front bumper, the service door, and the right front tire
C.The area 200 feet behind the bus, seen through the rear emergency window

About the AK CDL School Bus Exam

The Alaska CDL School Bus Endorsement Test is the Alaska Division of Motor Vehicles knowledge test for the School Bus (S) endorsement, which anyone driving a school bus to and from a public school needs along with the Passenger endorsement. The test is based on Section 10 of the Alaska CDL Manual: danger zones, mirrors, loading and unloading, evacuation, railroad crossings, student management, and special safety topics. Alaska also sets its own licensing rules in AS 28.15.046 and 4 AAC 27. This free bank is independent practice by OpenExamPrep built from those official sources.

Exam sponsor: Alaska Division of Motor Vehicles. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

For the School Bus (S) endorsement, the Alaska DMV requires a vision test, the General Knowledge, Passenger, School Bus, and Air Brakes knowledge tests (unless already held or you accept the L restriction) with at least 80% on each, and a road skills test in a representative school bus. This bank is an independent multiple-choice study aid, not a copy or simulation of the official test.

AK CDL School Bus: Suggested Study Strategy

1Learn the Section 10.1 danger zones: up to 30 feet in front (the first 10 feet most dangerous), 10 feet on each side, and 10 feet behind the bus.
2Keep the stop timing straight: amber lights at least 200 feet or 5 to 10 seconds before the stop, the right turn signal about 100 to 300 feet before pulling over, and red lights only once traffic is a safe distance away.
3For railroad crossings, stop 15 to 50 feet from the nearest rail, and use the containment rule: bus length plus 15 feet beyond the tracks.
4Know the Alaska rules in AS 28.15.046: age 21, three years of license history, approved training, background checks, and a five-year license term.
