Quick reference

Danger Zones and Loading/Unloading Students

  • The danger zone is the area within 10 feet of the school bus on all sides; students inside it are in the highest-risk zone for a bus-strike fatality.

  • Oklahoma law requires the bus driver to account for every student in the danger zone before moving the bus; a lost-count student means stop and re-check.

  • Loading/unloading sequence: stop, set parking brake, shift to neutral (or park), activate the 8-way light system, then open the door.

  • Students must cross far enough in front of the bus to see the driver's face (roughly 10 feet ahead) and wait for the driver's hand signal before crossing.

  • Never signal a student to cross until traffic in both directions has stopped and the driver has re-checked mirrors and the crossing path.

  • The driver counts students off the bus and counts them again at a safe point outside the danger zone; the count must match before the bus moves.

  • If a student drops an item near the bus, the student must leave it and tell the driver - never crawl under or reach beneath the bus.

  • The stop arm and red lights stay out until all students are clear of the danger zone and seated or safely off the roadway.

Post-Crash Procedures and Emergency Evacuation

  • Post-crash priorities in order: stop and secure the bus, protect the scene (hazard lights, triangles), check for injuries, notify dispatch/911, then evacuate only if there is fire, hazardous cargo, or a safer location exists.

  • Evacuation commands are given in a loud, calm voice: "Evacuate" followed by the direction (front door, rear door, or both) and the assembly point.

  • Front-door evacuation order: driver exits first and stands at the door to hand students down; rear-door evacuation uses two student helpers outside the door.

  • Students evacuate at least 100 feet from the bus and from the roadway, then assemble at a single designated point where the driver can recount them.

  • The driver takes the emergency kit, first-aid kit, and fire extinguisher when leaving the bus, and takes the roster to account for every student.

  • Never evacuate students into traffic lanes or toward the fuel spill side; move upwind and uphill of a spill or fire.

  • After any crash involving injury, a fatality, or a hit-and-run, the driver must notify law enforcement and remain at the scene; leaving is a criminal offense.

  • The driver documents the crash with names, license plates, insurance, witness statements, and photos before leaving the scene, if safe to do so.

Quick reference

Railroad-Highway Grade Crossings

  • Oklahoma school buses must stop at all railroad-highway grade crossings, whether or not the crossing is marked as an exempt crossing by the state.

  • Stop between 15 and 50 feet from the nearest rail - close enough to see, far enough to be clear of a passing train's overhang.

  • Before crossing: stop, set the parking brake, open the driver's window, turn off noisy equipment (heater, fan, radio), and listen.

  • Look and listen in both directions, then look again; a train at 55 mph needs about a mile to stop, so a visible train means wait.

  • Cross only when the bus can clear the entire crossing without stopping; never shift gears while on the tracks.

  • If the bus stalls on the tracks, evacuate students immediately and move them at least 100 feet away from the tracks, then call 911.

  • Never drive around a lowered gate or past flashing lights; a gate down means a train is coming even if none is visible.

  • After crossing, do not stop or shift until the rear of the bus has cleared the crossing by a safe distance.

Vehicle Inspection, Braking, and Antilock Brake Systems

  • Pre-trip inspection covers fluids, belts, tires, lights, mirrors, stop arm, emergency exits, first-aid kit, fire extinguisher, and the brake system, including the ABS warning light.

  • The ABS lamp should come on at start-up and go out; a lamp that stays on means ABS is disabled and the bus should be removed from service.

  • ABS does not shorten stopping distance on all surfaces; it prevents wheel lockup so the driver can steer during a hard stop.

  • With ABS, apply firm continuous pressure and hold it - do not pump the brake; pumping defeats the system.

  • Air-brake buses: check the air pressure build-up rate and listen for the low-pressure warning; a leak-down test confirms the system holds pressure.

  • The parking brake must hold the bus on a grade; Oklahoma requires the brake to be set whenever the bus is stopped for loading or unloading.

  • Brake fade on long downgrades is prevented by selecting a lower gear and using the engine brake, not by riding the service brakes.

  • A brake system defect found in pre-trip inspection must be reported and the bus taken out of service before carrying students.

Student Management and Special Situations

  • The driver's authority over students begins when they board and ends when they leave; the driver may assign seats and enforce rules, but not use corporal punishment.

  • Students with disabilities may require a written IEP or 504 plan accommodation; the driver follows the plan and keeps information confidential.

  • Bullying, fighting, or threats are documented and reported to the principal or dispatcher the same day; the driver does not handle discipline alone.

  • A student who refuses to obey safety instructions may be removed from the bus only at a safe stop under district policy, never left along a highway.

  • Special situations include a student left on the bus: check every seat and the floor after each run - a sleeping child left behind is a life-threatening event.

  • When a student is not met at the stop by a parent or guardian, the driver keeps the child on the bus and contacts dispatch rather than releasing them alone.

  • An unauthorized person attempting to board is denied entry; the driver secures the door and notifies dispatch and law enforcement.

Bus Stops, Loading Zone Safety, and Use of Lights/Signs

  • The 8-way light system: amber warning lights activate about 100 to 300 feet before the stop; red lights and stop arm activate only when the bus is stopped and the door opens.

  • The stop arm extends on the driver's left side; red lights flash front and rear while students load or unload.

  • Oklahoma requires traffic in both directions to stop for a school bus with red lights flashing on a two-lane road; on a divided highway, only traffic behind the bus must stop.

  • The driver confirms traffic has stopped before signaling students to cross; a vehicle that fails to stop means hold students and sound the horn.

  • Choose stops with clear sight distance and room for students to wait off the roadway; stops are placed so students do not cross more than one lane.

  • Hazard lights are used for a disabled bus or a stop where the 8-way system is not required; they do not replace red lights at a student stop.

  • Headlights are required in Oklahoma when visibility is poor and at night; daytime running lights do not satisfy the requirement for a school bus.

School Bus Vehicle Characteristics and Safe Driving Practices

  • A loaded school bus has a higher center of gravity and longer stopping distance than a passenger car; increase following distance to at least 4 seconds.

  • Swing wide on right turns because the rear wheels track inside the front wheels; check the right mirror for the rear axle path before completing the turn.

  • The blind spot behind a school bus extends about 200 feet; mirrors must be adjusted so the driver sees the rear bumper and the danger zone.

  • Backing is the highest-risk maneuver: use a spotter, sound the horn, and back only when necessary; never back toward students.

  • Speed and curves: slow before the curve, not in it, because a top-heavy bus can roll if the driver brakes hard while turning.

  • Railroad crossings, bridges, and narrow roads require reduced speed; the bus's height and weight limit clearance and lane width.

  • Distracted driving rules apply: no cell phone use while driving a school bus, and the driver keeps both hands on the wheel except to operate controls.
