The school-bus rule prohibits the listed interactive wireless devices whether or not hands-free. Its separate two-way voice-system provision is for assisting passenger transportation, not a general exception for personal calls.

Outside an applicable operations-check exception, an Arizona school-bus driver is leaving the compartment of a keyed, automatic-transmission bus. Which setup meets the rule?
Correct answer: Set the parking brake, select park or neutral, turn off and remove the key.
The automatic bus must have its parking brake set, transmission in park or neutral, and ignition off with its key removed. The rule separately specifies first or reverse for a standard transmission and power deactivation for a keyless ignition.

After unloading, an Arizona bus appears empty and its child-alert procedure has been completed. Is the driver excused from inspecting the interior?
Correct answer: No; the driver must also inspect for passengers and belongings.
The physical interior inspection and any required child-alert procedures are additional duties, not alternatives. Check every time unloading appears to leave no passengers aboard.

What minimum evacuation-drill participation does the Arizona school-bus rule require from each school-bus driver every school year?
Correct answer: At least two evacuation drills each school year.
Each school-bus driver must participate in at least two drills during every school year. The school's drills also include passengers present that day and instruction on exits, emergency equipment, safe movement and orderly conduct.

An Arizona school bus is involved in an accident. Alongside obtaining needed emergency assistance and notifying the appropriate law enforcement, when must the driver report it to the employer?
Correct answer: Immediately.
DPS directs the driver to report to the employer immediately. The employer then promptly notifies DPS by telephone and submits written verification within 72 hours of that telephone notification; the written deadline does not postpone the driver's report.

During an Arizona school-bus pre-trip check, the driver notices a malfunction but does not perform mechanical repairs. What responsibility remains with the driver?
Correct answer: Report the defect before it develops into a hazardous situation.
DPS places defect-reporting responsibility on the driver, who may be the only person aware of a malfunction. Not being the mechanic does not remove that duty.

A mechanic serviced an Arizona school bus yesterday. Before transporting passengers today, what does DPS still require of the driver?
Correct answer: A planned, systematic daily pre-trip inspection.
DPS requires the driver's planned, systematic daily pre-trip inspection before transporting passengers. Recent maintenance does not replace that inspection.

A coach riding on an Arizona school bus says that only students have to follow the driver's safety instructions. Is that correct?
Correct answer: No; adult passengers are also subject to the driver's instructions.
DPS expressly includes adult passengers such as coaches, teachers and monitors under the school-bus driver's authority. If someone refuses to comply, the driver may seek appropriate emergency assistance.

An empty Arizona school bus is moving on a public road, outside any garage or bus storage area. May its service door be left open because no students are aboard?
Correct answer: No; the door must remain closed while the bus is moving.
The DPS guidance applies the closed-door requirement whether or not pupils are aboard. This scenario excludes its garage and bus-storage-area exception.

An Arizona school-bus driver is returning an empty bus along a public road. What does the DPS guidance require about the driver's seat belt?
Correct answer: Wear it whenever the school bus is in motion.
The requirement is tied to the bus being in motion, not to the number of students aboard or the road type.

An Arizona school bus is approaching a required railroad stop. What minimum advance distance does the DPS checklist give for using the hazard warning lights?
Correct answer: 100 feet before the crossing.
The checklist directs use of hazard warning lights at least 100 feet in advance to warn motorists of the intended railroad stop. These hazards serve a different purpose from the alternating passenger-loading lamps.

Under the Arizona DPS school-bus checklist, by what distance from a railroad grade crossing should the driver shut off a radio or other source of sound?
Correct answer: Within 50 feet of the crossing.
The railroad guidance specifies shutting off sound sources within 50 feet of the crossing so the driver can listen. Stopping, looking and the other crossing precautions still apply.

A driver has checked an Arizona school bus's headlights and tail lamps. Is that enough to complete the daily checklist's lamp item?
Correct answer: No; the item includes the other listed lamps and warning devices.
The lamp item covers the applicable alternating, backup, clearance, hazard, identification, interior, marker, stop, turn and other listed lamps, as well as emergency warning devices. Checking two lamp types does not finish that item.

An Arizona school bus's emergency door opens mechanically. What related item must still be checked under the daily pre-trip checklist?
Correct answer: Its emergency-door warning signal.
The checklist lists emergency exits and doors together with their signals. Mechanical opening alone does not establish that a warning signal works.

The wheelchair securement straps on an equipped Arizona school bus have been inspected. Which related attachment must also be checked?
Correct answer: The wheelchair securement anchorages.
DPS lists wheelchair securement devices and their anchorages as separate inspection items. Checking the straps does not by itself check the points to which the system attaches.

The wheelchair lift on an Arizona school bus operates. Which additional related components appear on the daily checklist?
Correct answer: The lift dome lamp and special-service door and signal.
The checklist separately names the wheelchair lift and its dome lamp, plus the special-service entrance door and signal. Successful lift movement does not complete those other checks.

During an Arizona school-bus pre-trip, the service brake brings the bus to a stop. Does that alone complete the checklist's brake-related items?
Correct answer: No; parking-brake and applicable warning-device checks remain.
The checklist includes the service brake with its warning devices and separately lists the parking brake. One successful service-brake stop does not demonstrate the other functions.

A driver finds damaged floor covering during an Arizona school-bus daily inspection. What should happen to that finding?
Correct answer: Report the defect for attention rather than marking the item satisfactory.
Floor coverings and the school-bus body are listed inspection items, and the driver's duty includes reporting defects before a hazardous situation develops. A fault elsewhere is not required before this finding matters.

An Arizona school bus is fitted with a child-alert notification system. When preparing it for passenger transport, how should the driver treat that system?
Correct answer: Include the installed system in the daily pre-trip inspection.
The daily checklist includes the child-alert notification system if installed. Checking the equipment before a route does not replace the separate physical passenger search after unloading.

An equipped Arizona school bus's stop arm has been checked. Does that mean its front crossing control arm can be omitted from the daily inspection?
Correct answer: No; the installed crossing control arm is a separate item.
The checklist separately lists the stop arm and the crossing control arm when installed. Do not assume that checking one confirms the other's condition.

Emergency-equipment containers are present on an Arizona school bus. Is merely seeing the containers enough to finish the daily checklist's emergency-equipment item?
Correct answer: No; check that the equipment meets the cited applicable standards.
The checklist calls for checking emergency equipment against the applicable standards, not simply confirming that containers exist. Follow the relevant equipment requirements rather than assuming a visible box is ready for use.
