Smoke in the Cab with a Wheelchair Student Aboard
Bus 31, a 72-passenger conventional bus, is 2 miles from the middle school with 38 students aboard when you smell hot oil and see light gray smoke drifting from the defroster vents and around the steering column. It is 3:15 p.m. on a two-lane road posted 55 mph, with a guardrail on the left, an open field on the right, and a gravel driveway about 200 feet ahead on the right. Traffic is moderate in both directions. One student uses a wheelchair and is secured mid-bus with a dedicated aide; three other students have IEPs that require adult prompting. Your extinguisher is a 5 BC unit mounted behind the driver's seat, and you have a working radio. The last evacuation drill was in September.
1. Do you evacuate, or push on to the school or the driveway? Justify the call and describe how you stop.

Evacuate. Smoke coming from the defroster vents and around the steering column points to an electrical or engine-compartment fire already burning behind the dash, and both remaining options - two miles at 55 mph, or 200 feet across a driveway entrance with traffic turning in - keep 38 students sitting on top of it. Stop as soon as you can do it safely: signal, brake smoothly, hazards on, wheels straight, transmission in park, parking brake set, engine off, key in hand, battery disconnect off if the bus has one. The gravel driveway is worth taking only if you can enter it without crossing the oncoming lane; otherwise stop in your lane, because you are stopping in order to empty the bus, not to wait for a tow. Distance and wind between the students and the bus are the goal.
2. Give the evacuation sequence, including which exits you use and how the wheelchair student and the three IEP students are moved.

Secure the bus, then give one clear command: 'front door, leave everything, walk to the fence line, stay together.' Use the front service door only if the smoke is not sitting over the stairwell; with smoke at the dash it may be, so be ready to redirect everyone to the rear emergency door and send a calm older student to open it and hold it. Assign two students to lead and one to bring up the rear and pull the door shut. The wheelchair student goes with the aide plus one assigned helper to the nearest usable exit; deploy the lift or ramp only if it is fast and clear of smoke, and if it is not, transfer the student to a two-person carry and leave the chair. Call the three IEP students by name and pair each with a peer, because in smoke they will wait for an adult who may be busy elsewhere.
3. What happens at the assembly point, and what do you do about the seven-month gap since the last drill?
Read the worked answer
Assembly point 100 feet upwind in the field, clear of traffic and of anywhere the bus could burn. Then a head count by name off the route list, not by number, followed by a second count, with the aide personally confirming the wheelchair student. Radio dispatch with your location, student count, and any injuries; call 911 if there is fire, smoke, or injury. Nobody reboards for phones, backpacks, or medication until a fire officer clears the bus, and students stay grouped and supervised, because the moment they scatter your accountability collapses. Afterward, write the report and list every student and injury. Then address the drill gap: seven months between drills shows up as hesitation and wrong exits in a real evacuation, so schedule the next one within the required interval and practice the exits you just used, including a rear-door-only drill with the aide.
