The Vehicle Pre-Trip Checklist

Why this matters

The work truck is the heaviest, fastest, most dangerous thing your shop operates, and it starts every day carrying tools, tanks, and a person. A soft brake, a bald tire, or an unsecured ladder does not announce itself; it shows up at the worst possible moment. A pre-trip walkaround takes a couple of minutes and catches the failure in the yard instead of on the highway. This is a safety inspection first and a readiness check second, so it runs top to bottom with the life-safety items at the front. Do it before the truck moves, every day, not just when something already feels wrong.

Phase 1: The safety-critical walkaround

Walk around the vehicle before you get in. These are the systems that hurt someone if they fail.

• Tires: adequate tread, no bulges, cuts, or sidewall damage, and each one firm to the eye or gauged if it looks low. Check the inner duals if you run them.
• Wheels: lug nuts present and tight, no rust streaks trailing from a stud, no cracks.
• Lights all around: headlights, brake lights, turn signals, hazards, and reverse lights working, lenses intact.
• Leaks: no fresh puddle or drip under the engine, transmission, or brake lines. A wet spot is a warning.
• Glass and mirrors: windshield not cracked in the line of sight, all mirrors present and adjusted.
• Body and underbody: no dragging exhaust, no hanging trim, nothing that will come loose at speed.

Phase 2: In the cab, before you roll

Some failures only show when you sit down and check.

• Brakes: firm pedal that does not sink, and a parking brake that holds. Test the service brake at low speed before you leave the lot.
• Steering feels normal with no excess play, and the wheel is not off-center for a straight path.
• Gauges and warning lights: nothing lit that should not be, fuel adequate, temperature and oil normal once running.
• Horn, wipers, washer fluid, and defrost all work. You will need them the day you skipped checking.
• Seatbelt latches and retracts, and the seat is set for control.

Phase 3: Load and cargo securement

Loose cargo becomes a projectile in a stop or a wreck, and an unsecured ladder is a hazard to everyone behind you.

• Ladders and racks locked down, no strap frayed, no rung sticking into a traffic lane.
• Tanks and cylinders secured upright and capped, chained or strapped so they cannot shift or fall.
• Loose tools and heavy items stowed and restrained, not stacked on a seat or sliding in the bed.
• Rear doors, tailgate, and exterior boxes latched, and nothing overhanging that blocks a light or a plate.
• Load is within the vehicle's rating and reasonably balanced, not piled all to one side or over the axle limit.

Phase 4: Documents and readiness

• Registration, insurance, and any required permits are in the vehicle and current.
• Fuel or charge is adequate for the day's route, so the first stop is a job, not a station.
• The fire extinguisher and any required emergency gear are present and in date.
• Anything you found wrong is reported now, and a genuinely unsafe truck stays parked. A brake or tire defect is a do-not-drive, not a "watch it today."
