Massachusetts CDL School Bus Test cheat sheet

Danger zone is the area within 10 feet around the bus: front, rear, and both sides; the most dangerous area is directly in front of the bus and just behind the right rear wheels.

Massachusetts requires the school bus driver to account for every student in the danger zone before moving; students must be visible or confirmed clear before the bus moves.

Students crossing the roadway must cross at least 10 feet in front of the bus and wait for the driver's hand signal before crossing.

The stop arm, red flashing lights, and crossing gate deploy only when students must cross the roadway or enter/exit; use the 4-way hazard lights at other stops.

Loading/unloading may only occur at designated school bus stops; stopping on a curve, hill crest, or where sight distance is limited is prohibited when avoidable.

The driver must secure the bus (parking brake set, transmission in neutral or park per manufacturer, engine off when leaving the seat) before signaling students to approach.

Students must never retrieve an item dropped near or under the bus; the driver moves the bus only after all students are seated or clear of the danger zone.

At a stop, count students off the bus and count them back on; a missing count means the bus does not move until the student is located.

Massachusetts requires a pre-trip inspection before each trip and a post-trip inspection after each route; the post-trip check must include walking to the rear to confirm no child remains aboard.

Pre-trip items include tires and tread depth, wheel lug nuts and rust streaks, brakes and air pressure build-up, lights and reflectors, stop arm, crossing gate, mirrors, horn, wipers, and emergency exits.

Tire minimum tread depth for school buses is 4/32 inch on front steering tires; check for cuts, bulges, and proper inflation.

Air brake system: with engine off and full pressure, loss rate must not exceed 3 psi per minute (single vehicle) or 4 psi per minute (combination); low-air warning must activate by 60 psi.

The emergency exit buzzer or warning device must sound if an emergency exit is opened; a faulty warning is an out-of-service defect.

Required equipment includes fire extinguisher, first aid kit, body fluid cleanup kit, triangles or reflectors, and a seat belt cutter where equipped.

Any defect affecting safe operation places the bus out of service; the driver reports it and does not transport students until corrected.

Mirror adjustment: the crossover mirror must show the area in front of the hood and the front bumper; convex mirrors cover the sides and rear danger zone.

School buses must stop at all railroad-highway grade crossings, whether or not the crossing is marked as exempt; Massachusetts law requires the stop.

Stop between 15 and 50 feet from the nearest rail, set the parking brake, open the service door or driver window, and turn off noisy equipment such as fans and heaters.

Look and listen in both directions; proceed only when no train is approaching and there is room to completely clear the crossing on the far side.

Never shift gears while crossing the tracks; select the gear before starting across and maintain steady speed.

If the bus stalls on the tracks, evacuate students immediately, move them at least 100 feet away from the tracks and in the direction of an approaching train, then call for help.

Do not drive around lowered gates or cross when warning lights flash or a flagger signals stop; a gate arm alone does not guarantee a clear track.

At a multiple-track crossing, wait until all tracks are clear; a train on one track can hide a second train on another.

If a train approaches while the bus is on the tracks, move away from the track and toward the approaching train at an angle to avoid being struck by debris.

Evacuate only when staying aboard is more dangerous than leaving: fire, fuel leak, hazardous cargo spill, or bus in a dangerous position on a crossing or roadway.

Evacuation sequence: secure the bus, notify dispatch, assign student helpers, open exits, evacuate students to a safe distance (at least 100 feet from the bus and away from traffic), and account for all students.

Emergency exits include the rear door, side door, roof hatches, and window exits; know which exits operate on each bus model.

Fire evacuation: move students upwind and at least 100 feet away; never reboard a burning bus.

Student management rules: students remain seated, facing forward; the driver addresses misbehavior after the bus is stopped and secured, not while driving.

The driver may not use physical force except to protect students or others from imminent harm; report serious misconduct to the school administrator.

A written report of any evacuation or serious incident goes to the school district and the operator; Massachusetts requires reporting of accidents and incidents.

Drill the evacuation procedure so students know the exits, the assembly point, and the command to leave the bus.

Massachusetts school bus speed limit is 40 mph on any roadway, including highways, unless a lower limit is posted.

Red flashing lights and the stop arm must be used when students are loading or unloading and must cross the roadway; traffic in both directions must stop unless separated by a physical barrier or median.

On a divided highway with a median or barrier, only traffic on the bus's side must stop; the driver must not require cross-traffic to stop.

The driver must not back up at a loading zone; if backing is unavoidable, use a spotter and sound the horn, and never back with students outside the bus.

The bus must be stopped with parking brake set and transmission in neutral/park before the door opens and students exit.

Use of the stop arm is prohibited at locations where the bus is off the roadway and students do not cross, such as a school driveway or private property.

The driver is responsible for ensuring all students are clear of the bus before retracting the stop arm and moving.

Passing a stopped school bus with red lights flashing is a violation for other drivers; the bus driver records and reports violations to the operator and police.

Maintain a following distance of at least one second per 10 feet of vehicle length plus one second; for a 40-foot bus at speeds under 40 mph, that is at least 4 seconds.

Add one additional second for adverse conditions such as rain, snow, ice, or darkness.

Use the 4-second following rule as the minimum for school buses; increase to 6 or more seconds in poor weather or heavy traffic.

Shift to a lower gear before descending a steep grade; do not coast in neutral and do not ride the brakes continuously.

Use progressive shifting: upshift at the lowest rpm that maintains power, and downshift before the engine lugs on a climb.

Look 12 to 15 seconds ahead and check mirrors every 5 to 8 seconds; keep the bus centered in the lane and allow extra room for the long rear overhang on turns.

Swing wide on right turns to keep the rear wheels from off-tracking over the curb or into the danger zone; check the right convex mirror through the turn.

Stop smoothly and early; a loaded school bus needs significantly more stopping distance than a passenger car, especially on wet pavement.

When a hazard appears, brake first, then steer; a loaded bus has a high center of gravity and steering while braking hard risks a rollover.

If a tire blows, hold the steering wheel firmly, keep the bus straight, ease off the accelerator, and brake gently once control is regained.

If brakes fail, downshift progressively, use the parking brake gradually, and look for an escape ramp or open area; do not pump the pedal on an air brake system.

Skids: steer in the direction of the skid, release hard braking, and avoid abrupt steering; on ice, reduce speed before the skid begins.

In fog, rain, or snow, reduce speed, increase following distance, use low-beam headlights, and turn on hazard lights only when permitted by law.

Hydroplaning occurs at speeds above roughly 35 mph on wet pavement; ease off the accelerator and avoid braking until tires regain contact.

At night, reduce speed so you can stop within the distance illuminated by headlights; a school bus may not exceed its 40 mph limit at night.

When a hazard requires an emergency stop, stop the bus, secure it, evacuate if needed, and report the incident to dispatch.

All passengers must be seated while the bus is in motion; standees are not permitted on a school bus except when specifically authorized and seats are full.

Carry-on items must be secured so they cannot become projectiles; large items, athletic equipment, and instruments go in the aisle only if secured and not blocking the exit.

The aisle, emergency exits, and stepwells must remain clear at all times; nothing may be stored in front of an exit.

Weight distribution: keep heavy items low and between the axles; do not exceed the bus's gross vehicle weight rating (GVWR) or axle weight ratings.

Check that the load does not block the driver's view or the mirrors; the driver must have a clear view of the danger zone.

Passenger securement: students remain seated, seat belts used where equipped, and students are not permitted to move about while the bus is moving.

Loading at school: students board in an orderly line, use the handrail, and go directly to a seat; the driver counts students as they board.

Unloading: students exit one at a time, use the handrail, and move away from the bus to a designated safe spot before the bus moves.

Air brake system must build pressure to at least 100 psi (or manufacturer's specification) before the bus is moved; check the low-air warning and the emergency spring brakes.

Perform the air brake leak test: with engine off and brakes released, pressure loss should not exceed 3 psi per minute; with brakes applied, no more than 3 psi per minute for a single vehicle.

The parking brake must hold the bus on a grade; test it before each trip and set it whenever the bus is stopped for loading or unloading.

The braking system is out of service if the low-air warning fails, the pressure does not build, or a leak exceeds limits; the bus must not carry students.

Warning lights and buzzers must work for oil pressure, coolant temperature, alternator, and low air; a failed warning device is an out-of-service condition.

The bus must have working stop arm, red and amber lights, crossing gate, horn, and back-up alarm where equipped.

Inspection failure: any defect affecting safe operation is recorded on the Driver Vehicle Inspection Report (DVIR) and reported to the operator before the next trip.

A driver may not operate a bus with a known safety defect; the driver is responsible for refusing to drive an unsafe vehicle and documenting the refusal.

Massachusetts follows federal hours-of-service rules for commercial drivers: 11 hours driving after 10 consecutive hours off duty, within a 14-hour on-duty window.

The 30-minute break requirement applies after 8 cumulative hours of driving without at least a 30-minute interruption; school bus operations may use the short-haul exception where eligible.

The 60/70-hour rule limits on-duty time in 7 or 8 consecutive days; reset with 34 consecutive hours off duty.

Drivers must keep a record of duty status (logbook) unless operating under an exception; school bus drivers on intrastate routes may be exempt under state rules but must still track hours.

Fatigue signs: yawning, heavy eyes, drifting, missing signs, and slow reactions; the driver must stop in a safe place and rest, not push through.

Driver wellness: get 7-9 hours of sleep, avoid alcohol before duty, and report medications that cause drowsiness to the employer.

A driver may not operate a school bus within 8 hours of consuming alcohol or while impaired; Massachusetts has a lower legal limit for commercial drivers (0.04% BAC).

Report any illness, medication, or fatigue that could affect safe driving to the operator before starting a route.
