What limitation must a driver remember when using convex mirrors?
Correct answer: They do not show size and distance accurately
Convex mirrors provide a wider view but distort apparent size and distance.

What area are crossview mirrors primarily designed to reveal?
Correct answer: The front bumper danger zone and areas near the front wheels and service door
Crossview mirrors cover areas directly in front and beside the front of the bus that direct vision misses.

How should flat, convex, and crossview mirrors be used before moving near students?
Correct answer: Scan them in a logical sequence so no child or object is missed
A deliberate sequence covers overlapping danger zones without leaving a gap.

Who may change the location of an official school bus stop?
Correct answer: The appropriate school district official through written approval
Drivers should not change a stop without written district approval.

Approaching a California pupil stop where warning lights are required, when must an equipped bus activate its amber lights?
Correct answer: Beginning 200 feet before the stop
CVC 22112(a) specifies 200 feet, not an interchangeable time estimate. Turn the amber lights off at the stop and use the required red lights and stop arm. Statutory exceptions apply to some locations.

Where should the front bumper stop relative to students waiting at a designated stop?
Correct answer: At least 10 feet away
The distance makes students walk toward the bus where the driver can better observe them.

How should the bus be secured at each student stop?
Correct answer: Use Park if available, otherwise Neutral, and set the parking brake
Use Park when the transmission has it; otherwise use Neutral. Set the parking brake and complete the traffic safety checks before opening the door for students.

What should a driver do if a student expected at the stop cannot be accounted for?
Correct answer: Secure the bus, take the key, and check around and underneath it
A missing child may be in a danger zone and requires a direct check before moving.

After leaving the bus, how far should students move from its side?
Correct answer: At least 10 feet to a place clearly visible to the driver
Students should clear the side danger zone and remain visible.
Source: CA Commercial Driver Handbook § 10.2.3 Unloading Procedures on the Route ↗
What should a school bus driver do after missing a student’s unloading stop?
Correct answer: Do not back up; follow local procedures
Backing creates severe danger around children and is not the remedy for a missed stop.

Which students must the driver escort across an uncontrolled road at a school bus stop?
Correct answer: Prekindergarten through grade 8 students who need to cross
California requires the driver to escort these younger students using an approved handheld STOP sign.

Where must students walk when crossing the road from a stopped school bus?
Correct answer: In front of the bus
Crossing in front keeps students within the driver’s controlled field of view.

What should a student do after dropping an object near the bus?
Correct answer: Leave it, move to safety, and get the driver’s attention
Retrieving an object can make a child disappear from the driver’s view at the most dangerous moment.

What is a critical purpose of walking through the bus after a route?
Correct answer: Find sleeping students and items left behind
The post-trip also checks doors, windows, unique school-bus equipment, damage, and mechanical problems.

Which situation requires evacuation of a school bus?
Correct answer: The bus is on fire or threatened by fire
Fire, a bus stalled on or near tracks, imminent collision danger, unstable position, or certain HazMat danger requires evacuation.
Source: CA Commercial Driver Handbook § 10.3.1 Mandatory Evacuations ↗
Where is a general safe location after a roadside bus evacuation?
Correct answer: At least 100 feet off the road toward oncoming traffic
This placement reduces the chance that collision debris will strike students.
Source: CA Commercial Driver Handbook § 10.3.2 Evacuation Procedures ↗
What minimum upwind evacuation distance does the school-bus handbook give for a hazardous-material spill risk?
Correct answer: 300 feet
The handbook minimum is 300 feet upwind. This is not a guarantee of safety for every chemical or spill; follow emergency responders and use a farther safe location when required.

Where should a school bus normally stop at a railroad crossing?
Correct answer: No closer than 15 feet and no farther than 50 feet from the nearest rail
The driver stops 15 to 50 feet away where the best view is available.
Source: CA Commercial Driver Handbook § 10.4.3 At the Crossing ↗
What should the driver do with noise and openings while stopped for a railroad crossing?
Correct answer: Silence passengers and equipment, then open the service door and driver window to look and listen
Reducing noise and opening these points improves detection of a train.
Source: CA Commercial Driver Handbook § 10.4.3 At the Crossing ↗
How much clear space should generally be available beyond railroad tracks before committing the bus?
Correct answer: The bus length plus 15 feet
The full bus must clear the tracks even if traffic stops beyond the crossing.

How should a school bus driver brake during an emergency when the bus has ABS?
Correct answer: Apply needed braking force without pumping the brakes
Use the braking force needed to stop safely without pumping. ABS helps prevent brake-induced wheel lock but does not guarantee a shorter stop or prevent a rollover.
Source: CA Commercial Driver Handbook § 10.6.3 Braking With ABS ↗
What is the safest rule for backing a school bus?
Correct answer: Back only when no safe alternative exists, never with students outside, and use a lookout when possible
Backing is strongly discouraged; a school bus can also have up to three feet of tail swing.

Students are unloading when an argument begins inside the bus. What must remain your immediate focus?
Correct answer: Students outside until they are safely clear
Do not lose sight of unloading students while attending to an onboard problem.
Source: CA Commercial Driver Handbook § 10.5.1 Loading and Unloading ↗
A serious onboard behavior problem prevents safe driving. What should you do?
Correct answer: Secure the bus in a safe place and follow school procedures for assistance
Deal with serious behavior issues from a safely secured bus, not while trying to drive.
Source: CA Commercial Driver Handbook § 10.5.2 Handling Serious Problems ↗
May you put a disruptive student off at an arbitrary roadside location as punishment?
Correct answer: No, use school or the designated stop and follow assistance procedures
If safe driving is impossible, call the appropriate school authority or police rather than abandon a student.

A strong crosswind pushes against the side of the school bus. What response is appropriate?
Correct answer: Slow down, keep control, and stop safely if conditions require
The large side area catches wind; consult dispatch and wait safely when necessary.
Source: CA Commercial Driver Handbook § 10.7.2 Driving in High Winds ↗
As the front of your bus turns left, what should you watch on the right rear?
Correct answer: The tail swinging outward toward nearby people or objects
Check mirrors before and during turns; the rear overhang can swing outside the wheel path.
