NM CDL School Bus key terms

The area within roughly 10 feet around a stopped school bus where students are hardest for the driver to see. Drivers must account for every student leaving this zone before moving the bus.

Areas around the bus that mirrors do not fully reveal, including directly in front of the hood, behind the rear bumper, and along both sides. Drivers adjust mirrors and move their heads to check them.

The ordered steps for letting students off: stop, secure the bus, set the parking brake, check traffic, signal students when safe, count them out, and confirm they are clear before moving.

The ordered steps for boarding students: stop, secure the bus, open the door, supervise students crossing and entering, count them as they board, and secure the bus before departure.

A deliberate count or visual sweep confirming every student is accounted for, either aboard the bus or safely clear of it, before the driver moves the vehicle.

A required end-of-run walk through the bus to find students left asleep or behind. Drivers perform it after every route, and many districts require a signed or posted confirmation.

A complete stop required before crossing tracks, with the door opened if the law requires it, the bus placed so the driver can see and hear, and movement only after confirming no train approaches.

The habit of stopping before tracks, opening the door or window to listen, looking both directions along the rails, and proceeding only when certain no train is coming.

The amount of the bus body extending past the front axle. Long overhang means the rear can swing wide or clip objects, so drivers allow extra clearance in turns and at crossings.

The tendency of a bus's rear wheels to follow a tighter path than the front wheels during a turn. Drivers swing wide enough that rear tires clear curbs, poles, and pedestrians.

The outward movement of the rear of the bus when the front turns sharply. Drivers check mirrors and keep students and objects clear of the rear corner before turning.

The hazard created when a bus turns right and its rear wheels cut close to the curb, trapping a pedestrian or cyclist. Drivers check the right side and turn slowly.

The alternately flashing amber and red lights used to warn traffic. Amber warns that the bus is about to stop; red means traffic must stop while students load or unload.

The hinged sign that swings out from the left side of the bus when red lights flash, telling traffic in both directions to stop while students cross or board.

The arm at a railroad crossing that lowers to block traffic. A driver must never drive around or under a lowered gate, even if no train is visible.

A designated side or rear door for rapid evacuation, marked with instructions and often fitted with a buzzer or alarm that sounds when opened. Drivers must know each location on their bus.

A side or rear window designed to open fully as an escape route, usually marked and fitted with a release handle. Drivers verify it opens and stays open during pre-trip checks.

An opening in the bus roof that serves as an emergency exit, often used when the bus is on its side. Drivers confirm it opens and is not blocked by luggage or equipment.

A practice exercise in which students rehearse leaving the bus through front, rear, and side exits, including how to help younger or disabled riders and where to gather afterward.

A prearranged safe location away from the bus and traffic where evacuated students gather and are counted after leaving the vehicle.

The controlled removal of all passengers from a bus during an emergency, following a clear command, choosing the safest exit, and accounting for every student afterward.

The required walk-around check of lights, tires, brakes, mirrors, emergency equipment, and exits before driving. Defects found must be reported and corrected before the bus carries students.

The check performed after a run, including walking the bus for left-behind students, securing windows and doors, and reporting any mechanical problems found during the trip.

The pre-trip check that each emergency door, window, and roof hatch opens freely, latches securely, and has a working warning device where required.

A check that the service brake and parking brake hold the bus, often performed by applying the brake and confirming the pedal or air pressure holds steady before moving.

The sequence confirming an air-brake system builds and holds pressure, has no audible leaks, and that warning devices work. Required on buses with air brakes before driving.

Setting the flat, convex, and crossover mirrors so the driver can see the front bumper, both sides, and the crossing area behind the bus before every trip.

Curved mirrors that widen the driver's side and rear view. Objects appear smaller and farther away in them, so drivers must judge distance carefully when students are near.

The brake that holds a stopped bus in place. It must be set whenever the bus is stopped for loading or unloading and whenever the driver leaves the seat.

Flashing warning lights used when the bus is a hazard, such as stopped on the roadside or moving slowly. They are not a substitute for the red student-loading lights.

The license required to operate a commercial motor vehicle, including a school bus, issued after passing knowledge and skills tests for the vehicle class and endorsements held.

The license class for a single vehicle over 26,000 pounds gross weight, such as a conventional school bus, or any such vehicle towing a trailer under 10,000 pounds.

The maximum loaded weight a vehicle is designed to carry, set by the manufacturer. It determines the CDL class and the weight limits the bus must not exceed.

The loss of CDL privileges, temporary or permanent, for offenses such as serious traffic violations, driving while impaired, or leaving a child on a bus. Rules vary by state.

A major moving violation, such as excessive speeding, reckless driving, or improper lane changes, that can lead to suspension or disqualification of a CDL.

An order that a driver or vehicle may not operate until a defect or violation is corrected. Driving while out of service carries serious penalties and can disqualify the driver.

Carrying students with disabilities or medical conditions, which requires knowing the proper securement of wheelchairs, use of lifts, and individualized boarding and evacuation procedures.

The system of straps and tiedowns that locks a wheelchair to the bus floor, plus a separate seat belt for the rider. Both must be checked before the bus moves.

The driver's approach to keeping order aboard the bus through clear rules, consistent expectations, and calm intervention, without leaving the seat or taking attention from driving.

Any activity that takes the driver's eyes, hands, or mind off the road, such as disciplining students, using a phone, or adjusting equipment while the bus is moving.
