How to do a school bus pre-trip inspection, zone by zone

A good pre-trip is the same walk in the same order every morning, so nothing gets skipped when a driver is cold, tired or running late. If you're training a new driver — or tightening up how your drivers do it — here's how to do a school bus pre-trip inspection zone by zone, using the items on our free school bus pre-trip inspection checklist.

Your state's list and the bus maker's manual come first. Use this as the backbone, then add whatever your state, your districts and your buses require.

Before you start

• Park on level ground, set the parking brake, and chock the wheels if that's your company's rule.
• Have the checklist (paper or phone), a flashlight, and a way to note defects.
• Write down the bus number, date, odometer and your name at the top.
• Work in one direction and in the same order every day. Habit is what catches the one thing that's different.

How to do a school bus pre-trip inspection: the four zones

The school bus pre-trip inspection steps fall into four zones. Go through them in this order so you finish in the driver's seat, ready to test the brakes.

Zone 1: the walk-around (outside the bus)

Start at the front and walk all the way around. Look under, then at, then up:

• Under the bus — no fresh leaks: oil, coolant, fuel or brake fluid.
• Tires — tread depth, inflation, no cuts, bulges or exposed cord.
• Wheels and rims — no cracks; every lug nut present and tight.
• Suspension — springs, shocks and mounts not broken or leaking.
• Exhaust — secure, no leaks.
• Body — no loose panels, sharp edges or new damage.
• Mirrors — flat, convex and crossview mirrors clean, secure and adjusted.
• Glass — windshield and windows clean and not cracked.
• Emergency exits — rear door, side doors, windows and roof hatches open freely, and their alarms sound.

The lights, stop arm and crossing arm are easiest to check with the engine running and someone to help — or switch them on from the seat and walk around once more:

• Headlights, turn signals, brake lights, clearance and marker lights work.
• Eight-light warning system — the amber and red flashers — works.
• Stop arm extends, lights up and retracts.
• Crossing arm extends and retracts.

Zone 2: the engine compartment

Engine off, keys out of the ignition:

• Engine oil, coolant, power steering fluid and windshield washer fluid levels.
• Belts — tension right, no cracks or fraying.
• Hoses — no leaks, cracks or bulges.
• Battery — secure, terminals clean.

Zone 3: the driver's seat and brakes

Start the engine and work through the controls:

• Gauges read normal — oil pressure, voltage, temperature, fuel.
• Air brakes (if fitted): pressure builds in the normal time, leak-down is within limits, the low-air warning comes on, and the spring brakes apply. Your CDL manual and your state give the exact numbers.
• Hydraulic brakes (if fitted): the pedal is firm, with no fade.
• Parking brake holds the bus; service brakes stop it straight.
• Steering — no excessive play.
• Horn, wipers, heater and defroster work.
• Driver's seat belt works.
• Entrance door opens and closes properly; interior and step-well lights work.

Zone 4: the passenger area and emergency equipment

Walk the aisle to the back and back again:

• Seats secure, no torn cushions or sharp edges.
• Aisle and floor clear, no loose items.
• Fire extinguisher charged, secured and tagged.
• First-aid kit present and stocked; body fluid clean-up kit present.
• Reflective warning triangles present.
• Wheelchair lift and securements (if fitted) work.
• Two-way radio or phone works.

When something fails

1. 1Note the defect on the checklist, with as much detail as you can.
2. 2Tell dispatch or the shop before you leave the yard.
3. 3If it's a safety item — brakes, steering, lights, stop arm, emergency exits, tires — don't drive the bus until it's fixed or the shop clears it. Ask for a spare.
4. 4Sign the checklist and hand it in (or send it), even if everything passed.

How long does a school bus pre-trip take?

There's no single number. It depends on the bus, the length of your state's list, the weather, and whether the driver is new. What matters is that a careful pre-trip fits in the paid time you give drivers before the first run — so nobody is tempted to rush it.

Whether pre-trip time is paid is its own question — see are school bus drivers paid between routes.

At the end of the day

The pre-trip has a partner: the post-trip, starting with the child check — walking the whole bus so no child is left on board. See our school bus child check procedure and the free post-trip inspection checklist. For the end-of-day defect report many companies keep, see do school bus drivers need to fill out a DVIR.

Doing it in FleetCommander

Printing the pre-trip checklist is a fine start. When you want the records in one place, FleetCommander puts the same walk on the driver's phone: on My Day they tap Pre-trip inspection, mark each item Pass, Fail or N/A, add an optional photo under any item and say what's wrong under a failed one, fill in the odometer, sign and Submit. Sending the pre-trip also clocks the driver in when driver attendance is on.

A failed item becomes a defect automatically, with the note and photo, so the shop sees it without a phone call — and a failed item marked Safety-critical can take the bus out of service and notify managers. The checklist itself is yours: build templates for buses and vans under Inspections › Templates. More in the driver inspections guide, the inspection app page, and our post on moving pre-trips to the driver's phone.

Ava (Beta), the assistant in the app, saves the office some clicking: Which vehicles need an inspection?, Failed inspections last week or What's wrong with bus 102? She can also open the checklist for you — say Start an inspection and she opens that vehicle's checklist for you to fill in and sign.
