Quick reference

School Bus Vehicle Inspection and Equipment

  • Pre-trip inspection: walk the bus checking tires, wheels, lug nuts, lights, mirrors, stop arm, crossing gate, emergency exits, first aid kit, fire extinguisher, and belt cutter; report defects before driving.

  • Maryland requires a daily pre-trip inspection and a written post-trip inspection report; the driver must note any defect that could affect safety or lead to a breakdown.

  • Check the emergency exits (rear door, side windows, roof hatches) open and close freely and that buzzers/alarms sound when opened with the ignition on.

  • Test the eight-light warning system (amber and red alternately flashing lights) and the stop arm; the stop arm must extend fully and its red lights must flash when activated.

  • Mirror adjustment: the crossover mirror must show the area in front of the bus from the bumper to about 12 feet ahead so the driver can see students crossing in front.

  • Brake check: test air pressure build-up and loss, low-air warning, and parking brake; a school bus must have a working emergency (spring) brake that applies automatically at low pressure.

  • Tire rules: reject a tire with tread depth below 4/32 inch on front wheels (2/32 inch elsewhere), cuts, bulges, or exposed cords; check dual tires are not touching.

  • Interior check: seats secure, aisle clear, handrail tight, heater and defroster working, and no loose items that could become projectiles in a sudden stop.

Loading and Unloading Students

  • Stop the bus so students do not have to cross the road to board or leave when you can avoid it; load and unload in a safe, well-lit spot away from traffic.

  • Shift to Park (automatic) or Neutral with parking brake set, and turn off the engine before opening the door for loading or unloading.

  • Activate the eight-light system and stop arm; students must wait until the driver signals them to cross, and the driver must watch the crossing path until each student is clear.

  • Students crossing in front must walk at least 10 feet ahead of the bus so the driver can see them over the hood and in the crossover mirror.

  • Count students as they leave and again when they reach a safe point; never move the bus until you have accounted for every student.

  • When unloading at a school, follow the local procedure: students exit and move away from the bus; do not let them walk behind the bus.

  • If a student drops an item near the bus, they must tell the driver and not retrieve it themselves; the driver retrieves it or moves the bus first.

  • At railroad crossings and divided highways, stop the bus, open the door, and listen before proceeding; never allow students to cross a multi-lane road to board.

Student Management and Discipline

  • Maryland law makes the driver responsible for order on the bus; the driver may assign seats and must report serious or repeated misbehavior to the school administrator.

  • State the rules at the start of the year: remain seated, keep aisles clear, no loud noise, no eating or drinking, keep hands and objects inside the bus.

  • Use a calm, firm voice and address behavior by name and rule; avoid arguing with a student while the bus is moving.

  • If a fight or serious safety threat occurs, stop the bus in a safe place, secure the bus, and call dispatch or 911; do not physically restrain students unless trained and authorized.

  • For a disruptive student, first give a verbal warning, then a seat change, then a written referral; follow the district's progressive discipline plan.

  • Never put a student off the bus except at school or the student's assigned stop; never leave a student unsupervised.

  • Do not use the bus radio or phone for personal reasons; keep communication brief and related to safety or operations.

  • Document incidents with time, location, students involved, witnesses, and action taken; submit the report to the school the same day.

Quick reference

Railroad-Highway Grade Crossings

  • Maryland requires school buses to stop at all railroad-highway grade crossings, whether or not the crossing is marked with a stop sign or signals, unless a police officer or flagger directs otherwise.

  • Stop no closer than 15 feet and no farther than 50 feet from the nearest rail; shift to a lower gear and do not shift again until fully across the tracks.

  • Turn off all radios and fans, open the door (and window if needed), and listen before proceeding; look both ways and check for a second train.

  • If the gates are down, do not go around them; wait until they rise fully and the lights stop flashing.

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

  • After a stall, call 911 or the railroad emergency number posted at the crossing, and if a train is coming, move away from the tracks along the direction of the train's approach at a 45-degree angle.

  • Never stop on the tracks; make sure there is room on the far side to clear the crossing completely before starting across.

  • At a crossing with a flashing light or gate, a school bus must still stop and check, even when the signal says proceed.

Emergency Procedures and Safety

  • Evacuation order: stop the bus in a safe place, set the parking brake, turn off the engine, remove the key, and activate hazard lights; then direct students out the safest exit.

  • Use the rear emergency door, side door, or roof hatch depending on the hazard; fire favors the side door if it is clear, and a bus in water or on its side uses roof hatches.

  • Students evacuate in a line, leave belongings behind, and move at least 100 feet from the bus and upwind of a fire; account for every student by name.

  • Fire: pull the extinguisher pin, aim at the base of the fire, squeeze the handle, and sweep; only fight a small fire with a clear escape route.

  • First aid: check responsiveness and breathing, call 911, control bleeding with direct pressure, and do not move an injured student unless there is immediate danger.

  • Report emergencies by radio or phone with location, number of students, nature of the emergency, and injuries; stay on the line until released.

  • Post-trip: walk the bus front to back, check under seats and in the aisle, and ensure no student remains on board; this is required after every route.

  • If a bus is involved in a crash, secure the scene, check students, call 911, and do not move injured students unless there is fire or traffic danger.
