Michigan CDL School Bus Test key terms

A systematic walk-around and in-cab check of the bus performed before driving, covering lights, tires, brakes, mirrors, emergency exits, and warning devices so defects are found while the bus is still parked.

The required check of the bus after each route or trip, walking the aisle for sleeping or left-behind students and confirming the bus is empty, secure, and any mechanical problems are reported.

A check with the engine off and system charged that watches the air gauge for pressure loss with the brakes applied and released, confirming the air system holds pressure before the bus is driven.

A buzzer and light that activate when air pressure drops below a set level, alerting the driver that braking power is falling and the bus must be stopped safely.

A mechanical brake that holds a stopped bus in place; it must be set before students load or unload and before the driver leaves the seat for any reason.

The control used to choose drive, neutral, or reverse. It must be placed in the park or neutral position with the parking brake set whenever students are boarding or leaving the bus.

Any door, window, roof hatch, or other opening designed for rapid evacuation. Drivers must know the location, operation, and inspection status of every exit on the bus.

A convex mirror mounted at the front of the bus that lets the driver see the danger zone directly ahead of and beside the hood, including students crossing in front.

A curved mirror that widens the driver's field of view along the sides of the bus; objects appear smaller and farther away, so distance judgments must be made with care.

Setting each mirror so the driver can see the required reference points, such as the rear bumper, side of the bus, and danger zone, before every trip begins.

The area immediately around the bus where students are hardest to see, roughly ten feet in every direction, including directly in front, behind, and along both sides.

The designated place where students board or exit, chosen so they do not have to cross traffic and so the driver can supervise them with mirrors and direct sight.

Tallying students as they board and again as they leave, then comparing totals to the route list, so no child is left on the bus or unaccounted for at a stop.

A required end-of-route walk through the bus, front to back and back to front, looking under and between seats for any student left behind, with the result documented.

A child who dozes off and fails to exit, a leading cause of children being left on buses; drivers must physically check every seat rather than relying on a glance or a quiet bus.

A standard gesture the driver gives students to cross the road or to stop and wait, used together with the flashing lights and never replaced by a shout alone.

The amber and red lights on the bus: amber warns traffic that a stop is coming, and red, together with the stop arm, tells traffic to halt while students cross.

A swing-out sign on the left side of the bus that deploys with the red lights to signal traffic in both directions to stop while students load or unload.

Recognizing repeated physical or verbal intimidation on the bus, intervening early, separating students, documenting what happened, and reporting it through school channels rather than ignoring it.

The posted expectations for riding, such as staying seated, keeping aisles clear, using quiet voices, and following driver directions, explained to students at the start of the year.

A written report of a student's misconduct given to school administrators, describing the behavior, time, and prior warnings so the school, not the driver alone, decides consequences.

Managing student behavior and bus noise so the driver's attention stays on the road; the driver pulls over safely before dealing with a serious problem in the aisle.

A practiced rehearsal in which students leave the bus through a designated exit in an orderly way, so the response is automatic during a real fire, crash, or other emergency.

Getting all students off the bus quickly and to a safe gathering point after a crash, fire, or hazard, then accounting for each student by name or number.

A portable extinguisher carried on the bus, checked for charge and mounting during inspection and used only on small fires while students are moved to safety first.

Warning devices placed behind a stopped bus to alert approaching traffic, especially on a dark road or after a breakdown, at the distances required by regulation.

Flashing four-way lights used to warn other drivers that the bus is stopped, disabled, or moving slowly, such as during a breakdown or an emergency unloading.

The stocked medical kit required on the bus; the driver checks that it is present and complete during inspection and uses it only within the limits of trained first aid.

Any place where tracks cross the road; the bus must stop, open the door or window to listen, look both ways, and cross only when clearly safe, regardless of signals.

The point where a roadway and railroad tracks intersect at the same level, marked by signs, pavement markings, or signals that the driver must check before proceeding.

A railroad crossing signal that operates when a train approaches, such as flashing lights, bells, or gates; the bus still stops and verifies the track is clear before crossing.

A non-powered crossing warning such as a crossbuck sign, pavement markings, or a stop line that tells drivers to look and listen for trains themselves.

Michigan rules requiring traffic to stop for a school bus with red lights flashing and stop arm out, with specific duties on divided highways and for opposing traffic.

The added credential a licensed driver needs to operate a school bus in Michigan, requiring knowledge tests, a skills test, and a clean driving record.

The credential required to carry passengers for hire or in certain school-related service, covering loading, safety, and emergency duties in addition to the base license.

Watching students leave the bus and reach a safe place, keeping the red lights and stop arm on until they are clear of the danger zone and the roadway.
