Utah School Bus CDL Practice Test

This is a free 20-question practice test for the School Bus portion of the Utah Commercial Driver's License knowledge exam. Questions are pulled from a pool of 55 drawn from the AAMVA CDL Manual, which is the source document the Utah Driver License Division uses to write its actual exam.

How it works: Click an answer. The correct choice highlights in green, and you'll see a short explanation. Aim for 85% or better before you sit for the real test in Utah.

Question 1 of 20

Most school-bus fatalities of students happen:

Inside the bus
Outside the bus, in the danger zone, particularly during loading and unloading
In another vehicle
At the school

Correct. The majority of student deaths involving school buses occur outside the bus, often in the danger zone right after unloading.

Question 2 of 20

A school bus stopped on a highway during loading or unloading is protected by:

State laws requiring all approaching vehicles to stop (with limited divided-highway exceptions)
Federal law only
No law
State school district policy

Correct. State laws (informed by federal recommendations) require approaching vehicles to stop. Many states have stiff fines for passing a stopped school bus.

Question 3 of 20

During the loading process, students should:

Wait at the bus stop until the bus has fully stopped and the door is opened
Approach while the bus is moving
Cross before the bus stops
Run to the bus

Correct. Students wait until the bus has fully stopped, the parking brake is set, the door is opened, and the driver signals before approaching.

Question 4 of 20

When the bus must stop because of crossing students, you should also:

Use the crossing-control arm (if equipped), signaling students to walk far enough in front of the bus to be seen
Skip the crossing arm
Have them walk behind
Have them run

Correct. The crossing-control arm extends in front of the bus, forcing students to walk where the driver can see them.

Question 5 of 20

You see a student running back toward the bus after being unloaded. You should:

Wait until the student is clear, account for them, before moving
Continue moving
Honk and accelerate
Open the door while moving

Correct. Stop and account for the student. Many fatal incidents involve students returning for forgotten items in the danger zone.

Question 6 of 20

Student management is important because:

Distracted driving by managing students causes crashes
It does not affect driving
Only the bus matters
Students never affect safety

Correct. Distracted driving from student-management issues is a leading cause of school-bus crashes. Pull off safely to address behavior.

Question 7 of 20

A school bus evacuation is required when:

Fire is on or in the bus, the bus is in danger of fire (downed wires, fuel spill), the bus is on or near tracks, the bus is in path of a train, or the bus is in danger of being hit
Only when the bus is empty
Only at night
Only after a flat tire

Correct. Evacuate for fire, danger of fire, on/near railroad tracks, in path of a train, or danger of being hit by another vehicle.

Question 8 of 20

When a bus is in motion, students must:

Remain seated, facing forward, not block the aisle
Stand
Move around
Sit on the floor

Correct. Seated, facing forward, hands and feet to themselves, aisle clear. This protects them in any sudden stop.

Question 9 of 20

When you approach a railroad crossing in a school bus, you must stop:

Between 15 and 50 feet from the nearest rail
On the tracks
100 feet ahead
Anywhere within 200 feet

Correct. Stop 15 to 50 feet from the nearest rail, open door and driver window, look and listen, then proceed without shifting gears.

Question 10 of 20

A school bus driver should never:

Allow students to use the emergency exits as routine entry/exit points
Allow students to be seated
Use the parking brake
Stop at red lights

Correct. Emergency exits are for emergencies. Routine use is unsafe and may damage the door or trigger interlocks.

Question 11 of 20

When backing a school bus, you should:

Avoid backing whenever possible; if you must back, use a helper, sound the horn, never back across a roadway, never back with students aboard if avoidable
Back at full speed
Back with no warning
Back across roadways

Correct. Backing in a school bus is the highest-risk maneuver. Avoid it. If required, use a helper, sound the horn, do not back across roadways, and ideally do not back with students aboard.

Question 12 of 20

A school bus must have how many mirrors at minimum?

Standard side mirrors plus crossover mirrors that allow the driver to see the danger zone in front and on the right side
Just one
Just two
None

Correct. School buses have side mirrors plus crossover mirrors at the front so the driver can see the danger zone in front of the bus and on the right.

Question 13 of 20

When evacuating students, they should be moved to a safe area:

At least 100 feet off the roadway in the direction of oncoming traffic, away from the bus
Right next to the bus
Across the road
Anywhere

Correct. Move students at least 100 feet away, off the roadway, in the direction of oncoming traffic so they can see and be seen by approaching drivers.

Question 14 of 20

Securing the bus at the end of the day:

Park in designated area, set parking brake, turn off engine and lights, secure all doors
Leave the engine running
Skip the parking brake
Leave doors unlocked

Correct. Standard end-of-day securement: parking, brake, engine off, lights off, doors secured. Walk through to ensure no children remain.

Question 15 of 20

A school bus driver who notices fluid leaks during pre-trip:

Should determine the type and source, and not put the bus in service if any safety-critical leak is found
Ignore them
Only address oil leaks
Address only at end of day

Correct. Identify what is leaking. Brake-fluid, fuel, or coolant leaks render the bus unsafe. Repair before service.

Question 16 of 20

Before resuming travel after a stop, the driver should:

Mirror-check, count students, verify all are clear of the danger zone, deactivate the lights, then proceed slowly
Drive immediately
Only check the rear
Skip the count

Correct. Mirror sweep, count crossing students, verify clear danger zone, deactivate lights and stop arm, proceed slowly.

Question 17 of 20

When students must cross the road to reach or leave the bus, they should:

Cross at least 10 feet in front of the bus, where the driver can see them, only on the driver's signal
Cross behind the bus
Cross at any time
Cross at the rear

Correct. Crossing students walk at least 10 feet ahead of the bus, in clear view, after the driver signals it is safe.

Question 18 of 20

A school bus must stop at every railroad crossing:

Yes, with limited exceptions
No, never
Only if a train is in sight
Only at night

Correct. School buses must stop at every railroad crossing 15 to 50 feet from the nearest rail. Open the entrance door and driver window, look and listen, then proceed without shifting gears.

Question 19 of 20

A "post-trip" inspection of the school bus should include:

Walk every aisle, check every seat, check restrooms or rear compartments where applicable
Skip the walk-through
Look only at front
Skip seats

Correct. Post-trip = walk every aisle, check every seat, all compartments. Document on DVIR.

Question 20 of 20

The minimum distance the front bumper of a stopped school bus should be from waiting students at the stop:

At least 10 feet
As close as possible
At least 1 foot
At least 50 feet

Correct. Stop with the front bumper at least 10 feet from waiting students so they have to walk forward to enter the bus, ensuring the driver can see them.
