School Bus Endorsement Knowledge

  • New York requires the school bus endorsement (S) plus a passenger (P) endorsement; drivers must hold a CDL with both to operate a school bus with students aboard.

  • Pre-trip inspection items unique to school buses: stop arm extends and retracts fully, red/amber eight-way lights flash, crossing gate swings freely, emergency exits open from inside and outside, and the bus's first-aid kit and fire extinguisher are present and charged.

  • Loading: students must be seated and silent before the bus moves; the driver counts students at each stop and confirms the count before departing, and again after unloading.

  • Unloading decision rule: the driver signals students to cross only after the stop arm is out, red lights are flashing, and the driver has confirmed traffic in both directions has stopped.

  • Students who must cross the road cross in front of the bus, far enough ahead to remain visible to the driver, and wait for the driver's hand signal before proceeding.

  • Emergency evacuation: stop the bus, set the parking brake, shut off the engine, activate hazard lights, and evacuate students to a safe location at least 100 feet from the bus and away from traffic.

  • A driver may never leave a school bus unattended with students aboard; if the driver must exit, students stay seated and the driver remains within sight and voice contact.

  • Report any student misconduct or safety incident to the district in writing the same day; physical discipline and removing a student from the bus are not permitted.

General CDL Knowledge

  • Pre-trip inspection sequence: engine compartment (fluid levels, belts, hoses, steering, suspension), then walk-around (lights, tires, brakes, coupling), then in-cab checks (gauges, horn, wipers, brake tests).

  • Air brake leak test: with the engine off and full pressure, the system must lose no more than 3 psi in one minute with the brakes released, and no more than 4 psi in one minute with the brakes applied.

  • Tire tread minimums: 4/32 inch for steering axle tires, 2/32 inch for all other tires; check for cuts, bulges, and matching tire sizes on duals.

  • Backing rule: get out and look (GOAL) before backing; if you cannot see behind the vehicle, use a spotter and stop immediately if you lose sight of the spotter.

  • Shifting: double-clutch or float gears per the transmission; do not coast in neutral downhill, and select a gear low enough to control speed before starting down a grade.

  • Speed management: reduce speed by at least 10 mph below the posted limit on curves, ramps, and wet roads; increase following distance to at least one second per 10 feet of vehicle length.

  • Communication: signal at least 100 feet before a turn (200 feet at highway speeds), flash brake lights when slowing, and use four-way flashers when moving slowly or stopped in traffic.

Safe Driving

  • Hazard perception: scan 12-15 seconds ahead, check mirrors every 5-8 seconds, and identify escape routes before entering intersections or work zones.

  • Distracted driving: text messaging and handheld phone use are prohibited for commercial drivers; a single glance away from the road should not exceed 2 seconds.

  • Fatigue rule: after 8 consecutive hours off duty, a driver may drive up to 11 hours and must take a 30-minute break after 8 cumulative hours of driving.

  • Railroad crossings: stop 15 to 50 feet from the nearest rail, look and listen, and do not cross until you are certain no train is approaching; never stop on the tracks.

  • School buses must stop at all railroad crossings, including those with active warning devices, unless a police officer or flagger directs otherwise.

  • Work zones: obey posted reduced speeds, merge early, and maintain extra following distance; fines for moving violations in work zones are doubled in New York.

  • Wet roads: hydroplaning begins at roughly 35 mph with worn tread; reduce speed, avoid sudden braking, and increase following distance to at least 4 seconds.

Transporting Passengers and Cargo Safety

  • Passenger safety: all riders must be seated with seat belts fastened (where equipped) before the vehicle moves; standees are not permitted on school buses.

  • Cargo securement: aggregate working load limit of tiedowns must be at least 50 percent of the cargo weight, and cargo must not extend more than 4 feet beyond the rear of the vehicle without a flag or light.

  • Load distribution: keep the heaviest items low and centered over the axles; the load must not exceed the vehicle's gross vehicle weight rating (GVWR) or any axle rating.

  • School bus cargo: backpacks and instruments must be stored so they do not block aisles, emergency exits, or the driver's view; nothing may be placed in front of the stop arm.

  • Passenger count: the driver must account for every student at every stop; an accurate count is the primary defense against leaving a child on the bus.

  • Hazardous materials: school buses may not carry hazardous materials except small quantities for the vehicle's own operation; never transport gasoline or propane in the passenger compartment.

  • Loading/unloading zone: stop with the bus parallel to and within 12 inches of the curb where practical, set the parking brake, and place the transmission in park before opening the door.
