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 Oregon.

Question 1 of 20

The "danger zone" around a school bus is generally:

10 feet in front, on each side, and behind the bus, plus any area required for the bus to maneuver
Only behind the bus
Only in front
5 feet on each side

Correct. The danger zone extends 10 feet in front, 10 feet on each side, and 10 feet behind the bus, plus the area needed to maneuver. Most students killed by their own bus are in this zone.

Question 2 of 20

When you change a flat tire en route with students aboard:

Move students to a safe location off the bus and away from the road
Have them stay aboard
Have them help
Have them stand near the tire

Correct. Move students to safety off the road during any tire change or breakdown. Risk of being struck or jack failure.

Question 3 of 20

When approaching the bus stop, you should activate the alternating amber warning lights:

About 200 feet in advance (more in 50+ mph zones)
At the stop
After unloading
Only at night

Correct. Activate amber warning lights about 200 feet before the stop (further in higher-speed zones), giving traffic time to slow.

Question 4 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 5 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 6 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 7 of 20

The school bus stop arm:

Extends to signal traffic to stop while children load or unload
Is decorative
Is for parking
Is optional

Correct. The stop arm signals approaching traffic to stop. Drivers who pass a stopped school bus with red lights flashing face heavy fines.

Question 8 of 20

When you encounter a railroad crossing without warning devices on a low-traffic spur:

Some states permit no-stop with conditions; verify the bus operator's policy
Skip stop always
Drive across without looking
Only if police direct

Correct. Limited exceptions exist for industrial spurs and abandoned tracks. Always verify and prefer to stop when in doubt.

Question 9 of 20

After delivering students to school in the morning:

Walk through the bus to verify no students remain
Lock and leave immediately
Only walk if requested
Skip the walk

Correct. Walk every aisle, every seat. Confirm bus is empty before leaving for the day or for the next trip.

Question 10 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 11 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 12 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.

Question 13 of 20

A pre-trip mirror adjustment should:

Allow the driver to see the right-rear and left-rear of the bus, the danger zone in front, and along both sides
Only show the rear
Only show the front
Not be necessary

Correct. Adjust mirrors to cover front danger zone, both sides, and the rear. Recheck adjustment after any seating-position change.

Question 14 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 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.

All standard items plus emergency exits, signaling devices (red and amber lights, stop arm, crossing-control arm), wheelchair lift if equipped, first-aid kit, fire extinguisher, body fluid clean-up kit
Only the engine
Only the brakes
Only the seating

Correct. Standard CMV inspection plus school-bus-specific equipment: lights, stop arm, crossing arm, lift, kits, mirror condition.

Question 16 of 20

When a school bus is on a divided highway with a barrier or median:

Some states allow vehicles on the opposite side not to stop when the bus is stopped — verify state law
Always require stop
Always require pass
Are not regulated

Correct. Most states exempt opposing traffic on divided highways with a physical barrier. Some require all traffic to stop. Know your state law.

Question 17 of 20

After unloading at the end of the route, the driver must:

Walk through the bus to check for sleeping or hiding students, lost items, damage
Skip the walkthrough
Lock and leave
Only check the front

Correct. Always walk every aisle and check every seat. Sleeping children left aboard a parked bus is a recurring tragedy that the post-trip walk prevents.

Question 18 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

Stop in the road
Drive into the school yard
Honk to clear traffic
