Question 1 of 25Score 0
What is the school-bus danger zone?
Answer: The area around the bus where children are hard or impossible to see
Children can disappear from direct view or mirrors near the bus, so the driver must account for them before moving. Study: School Bus — danger zones
What should flat outside mirrors show?
Answer: The bus sides and traffic to the rear
Properly adjusted flat mirrors help monitor traffic, the bus sides, and the rear approach area. Study: School Bus — flat mirrors
When should school-bus mirrors be adjusted?
Answer: Before operating the bus
Correct adjustment before the route gives the driver the intended view of traffic and danger zones. Study: School Bus — mirror adjustment
Where should the driver stop for students?
Answer: At the designated stop in a position that protects the danger zone
Use the approved stop and current local positioning procedure rather than improvising a stopping place. Study: School Bus — designated stops
When should students approach the bus?
Answer: After it stops and the driver signals that it is safe
The driver must establish control of the stop before students enter the danger zone. Study: School Bus — student loading
What should a driver verify after students board?
Answer: They are seated and all danger zones are clear
Before moving, account for students and confirm no one remains where the bus could strike them. Study: School Bus — student accounting
What should a student do after dropping an object near the bus?
Answer: Leave it, move to safety, and get the driver’s attention
A child retrieving an object can disappear from view, so the driver must know the child’s position. Study: School Bus — dropped objects
When should a student begin crossing in front of the bus?
Answer: After the driver signals and the student checks traffic
The driver’s signal does not replace the student’s own traffic check; both are necessary. Study: School Bus — crossing signals
Why are loose drawstrings dangerous during boarding?
Answer: They can snag on the handrail or door
A snagged item can trap a student as the bus moves, so the doorway area must be watched. Study: School Bus — handrail hazards
What is a key purpose of the post-trip inspection?
Answer: Find sleeping or hidden students
Walking through after a route ensures no child remains and identifies safety or security issues. Study: School Bus — post-trip inspection
When is evacuation mandatory?
Answer: When remaining aboard creates greater danger, such as fire or threatened collision
Fire, certain track situations, and imminent danger require prompt evacuation. Study: School Bus — evacuation decisions
Where should evacuated students be taken?
Answer: To a safe location away from traffic and the bus hazard
The assembly area must suit the emergency, including wind direction when fire or hazardous material is involved. Study: School Bus — evacuation location
What must happen at the evacuation assembly area?
Answer: Account for every student and keep the group together
A head count and group control prevent missing students and protect them from secondary hazards. Study: School Bus — evacuation accounting
At a school-bus railroad crossing, what should the driver do after stopping and silencing the bus?
Answer: Open the service door and driver's window, then look and listen for a train
The California school-bus procedure calls for opening the service door and driver's window after stopping, then looking and listening for an approaching train before proceeding. Study: California CDL Handbook — Section 10.4
How should a manual-transmission bus cross railroad tracks?
Answer: In a gear that carries it across without shifting
A missed shift can stall the bus on the tracks, so select the correct gear before crossing. Study: School Bus — railroad gear
What if a crossing gate lowers after the bus is committed?
Answer: Continue through instead of stopping on the tracks
Once committed, clearing the tracks is the priority; crossing gates are designed to break away. Study: School Bus — crossing gates
Does ABS always shorten stopping distance?
Answer: No
ABS primarily prevents lockup and preserves control; stopping distance varies by conditions. Study: School Bus — ABS limitations
When should serious student behavior be addressed?
Answer: After stopping in a safe place
Driving requires full attention, so serious discipline issues wait until the bus is safely secured. Study: School Bus — student management
Where may a student normally be discharged?
Answer: At school or the student’s designated stop
Follow school policy and never discharge a child at an unauthorized or unsafe place. Study: School Bus — student discharge
How should a driver respond to strong crosswinds?
Answer: Reduce speed and pull over safely if control is threatened
A high-profile bus is vulnerable to wind, and a safe stop may be necessary. Study: School Bus — high winds
How far from the nearest rail should a school bus normally stop at a railroad-highway grade crossing?
Answer: Between 15 and 50 feet
The California school-bus material requires the bus to stop between 15 and 50 feet from the nearest rail at a railroad-highway grade crossing, subject to listed exempt situations and local procedures. Study: California CDL Handbook — Section 10.4
How far may the California school-bus danger zone extend in front of the bus?
Answer: As much as 30 feet
California's school-bus section says the danger zone may extend as much as 30 feet in front, with the first 12 feet being the most dangerous. Drivers must use mirrors and procedures to account for children around the bus. Study: California CDL Handbook — Section 10
How far does the California school-bus danger zone extend to each side and behind the bus in the handbook illustration?
Answer: About 12 feet
The California handbook describes danger zones extending about 12 feet to the left, right, and rear. The front can extend farther, and the left side has added danger from passing traffic. Study: California CDL Handbook — Section 10
What rule applies to many passengers on a California bus equipped with seat belts?
Answer: They must be properly restrained as required by California law
California's school-bus section notes state seat-belt requirements for passengers on buses equipped with belts, subject to statutory exceptions. Drivers and operators should follow the current California rule and local district procedures. Study: California CDL Handbook — Section 10
What local information should a California school-bus driver know in addition to the CDL handbook?
Answer: California and local school district laws and procedures
The California handbook expressly tells school-bus drivers to be familiar with California and local school district laws and regulations. Local loading and student-management procedures can be more specific than general CDL guidance. Study: California CDL Handbook — Section 10
