For a new school-bus endorsement, what must an applicant do in addition to the school-bus knowledge test?
Correct answer: Qualify for P and pass the required school-bus driving test.
The S endorsement requires qualification for the passenger endorsement and a driving skills test in a school bus of the appropriate vehicle group. Practice quizzes do not satisfy these licensing or training requirements.

A child disappears beside your stopped bus. Which area needs attention?
Correct answer: The danger zones around every side of the bus.
Children can be hidden close to the front, sides or rear. The left side also exposes them to passing traffic; a single mirror view is not a complete check.

You take over a school bus from a taller driver. What should happen before you operate it?
Correct answer: Check and adjust each mirror for your own seated view.
Mirror coverage depends on the driver's position. Check all mirrors before operation and have any inadequate view corrected.

What should properly adjusted outside flat mirrors show on a school bus?
Correct answer: Bus sides, rear tires at ground level and traffic behind.
Flat mirrors help monitor side clearances and rear traffic. They do not remove the close-in blind spots in front of or behind the bus.

A vehicle looks small in a school bus's convex mirror. What must the driver remember?
Correct answer: Its apparent size and distance can be distorted.
Convex mirrors widen the viewing area but distort apparent size and distance. Use them together with the other mirrors and direct observation.

During a mirror check, which view belongs in the outside convex mirrors?
Correct answer: The bus sides and at least one adjacent lane on each side.
The handbook calls for side coverage up to the mirror mounts, the front of the rear tires touching the ground, and an adjacent lane on each side.

Which mirror system helps reveal a child directly in front of the bus below normal direct sight?
Correct answer: The outside crossover mirrors.
Crossover mirrors cover the front bumper danger zone and areas near the front wheels and service door. They supplement direct vision rather than replacing the other mirrors.

How should crossover-mirror coverage meet the area you can see directly ahead?
Correct answer: The mirror view and direct view should overlap.
Overlapping views help avoid an unseen gap in the front danger zone. Proper adjustment includes the front bumper area at ground level and the front tires.

Can the overhead inside mirror replace exterior checks before you leave a student stop?
Correct answer: No; it primarily monitors the passenger compartment.
The interior mirror is mainly for observing students. Its limited rear view and blind spots do not replace the exterior mirror checks for traffic and children.

A parent asks you to move a school-bus stop to another driveway. What does the Ohio CDL manual require before changing it?
Correct answer: Obtain written approval from the appropriate district official.
The manual describes district-approved stops and written approval before changing a stop. A parent request is not that approval. Follow the district emergency procedure when an immediate hazard affects an approved stop.

As you slow for a student stop, when should you check for children and traffic?
Correct answer: Before, during and after bringing the bus to a stop.
Approach cautiously while repeatedly scanning pedestrians, traffic and the mirrors. A situation can change while the bus is slowing or stopped.

When practical, approximately how far before a regular Ohio student stop should alternating amber warning lamps be activated?
Correct answer: 300 feet before the stop.
Ohio specifies approximately 300 feet before the stop whenever practical. The older handbook gives general timing and distance examples subject to state law; those examples do not replace the Ohio rule.
