Pre-Trip Inspection Checklist for Truck Drivers

A good pre-trip inspection checklist is the cheapest safety program you will ever run. It catches problems in the yard instead of on the shoulder or at a weigh station, and it protects your CSA scores and your schedule. Use the checklist below as a daily routine, and adjust it for your truck, trailer and state CDL manual.

Why the pre-trip matters

Federal rules (49 CFR 396.13) require a driver to be satisfied that the vehicle is in safe operating condition before driving. If the last driver vehicle inspection report listed defects, you must review it and confirm repairs were certified before you drive.

The practical reasons are just as strong:

• Roadside inspections often find lights, tires and brakes, which a walkaround catches.
• Out-of-service orders cost you the load, the appointment and sometimes the customer. See DOT roadside inspections and out-of-service criteria.
• A breakdown on the road costs more than the same repair in a shop.

Work in the same order every time

The order matters less than doing it the same way daily so nothing gets skipped. A common flow:

1. Approach the vehicle: look for leaks, leaning and damage
2. Engine compartment
3. Start engine and inside the cab
4. Lights check
5. Walkaround: front, driver side, rear, passenger side
6. Coupling and trailer
7. Air brake checks
8. Documents and emergency equipment

The checklist

1. Approaching the vehicle

• [ ] Puddles or fresh drips of oil, coolant, fuel or other fluid under the truck
• [ ] Truck or trailer leaning, which can point to suspension or tire problems
• [ ] New damage since you last drove it

2. Engine compartment (engine off)

• [ ] Engine oil level
• [ ] Coolant level and condition of radiator and hoses
• [ ] Power steering fluid and hoses
• [ ] Belts: tension, cracks, fraying
• [ ] Air compressor, mounted securely, no leaks
• [ ] Wiring: no chafed or loose wires
• [ ] Windshield washer fluid

3. Cab and engine start

• [ ] Gauges read normal: oil pressure, coolant temperature, voltage
• [ ] Air pressure builds within normal range and time, governor cuts out where it should
• [ ] Low air warning works
• [ ] Horn(s), wipers, defroster and heater
• [ ] Mirrors clean, adjusted and secure
• [ ] Windshield free of cracks in the driver's view
• [ ] Seat belt works
• [ ] Steering wheel play within limits
• [ ] Parking brake holds

4. Lights and reflectors

• [ ] Headlights (high and low)
• [ ] Turn signals and four-way flashers
• [ ] Clearance, marker and identification lights
• [ ] Brake lights and tail lights
• [ ] Reflectors and reflective tape clean and in place
• [ ] Trailer ABS warning lamp works as designed

5. Tires, wheels and hubs

• [ ] Tread depth meets at least the out-of-service minimums (generally 4/32 inch steer, 2/32 inch others)
• [ ] Inflation with a gauge, not a thump
• [ ] No cuts, bulges, exposed cords or mismatched sizes on duals
• [ ] Nothing stuck between duals
• [ ] Rims not cracked or bent
• [ ] Lug nuts present, tight, no rust streaks
• [ ] Hub oil level and no leaks at seals

6. Brakes and suspension (each axle)

• [ ] Slack adjusters and pushrods: not out of adjustment
• [ ] Brake chambers secure, no air leaks
• [ ] Air hoses not cracked, chafed or kinked
• [ ] Drums or rotors free of cracks, linings not too thin
• [ ] Springs, hangers and U-bolts: nothing broken, cracked or missing
• [ ] Air bags (if equipped) holding air, no leaks
• [ ] Shocks secure, not leaking

7. Coupling and trailer

• [ ] Fifth wheel securely mounted, no cracks, properly greased
• [ ] Locking jaws closed around the kingpin, release arm locked
• [ ] No gap between the fifth wheel and the trailer apron
• [ ] Glad hands and air lines connected, no leaks
• [ ] Electrical cord plugged in and secure
• [ ] Landing gear fully raised, crank handle secured
• [ ] Trailer doors, hinges and seals secure
• [ ] Mud flaps, frame and crossmembers not damaged
• [ ] Load secured (for flatbed, see flatbed cargo securement)

8. Air brake checks

These are general steps. Your state CDL manual lists the exact procedure and pass limits for your vehicle, so follow it. - [ ] Static leak test: with brakes released and engine off, air loss stays within the allowed limit for one minute - [ ] Applied leak test: holding full brake application, loss stays within the allowed limit - [ ] Low air warning activates at or before the required pressure as you fan down - [ ] Spring brakes apply automatically as pressure drops into the required range - [ ] Air pressure builds back up within the expected time - [ ] Tug test with parking brakes and trailer brakes - [ ] Service brake test at low speed

9. Documents and emergency equipment

• [ ] Driver's license and medical card (see medical card and DOT physical)
• [ ] Registration and cab card, proof of insurance
• [ ] Permits and IFTA documents as needed
• [ ] ELD user guide, malfunction instruction sheet and blank paper logs
• [ ] Bill of lading and any hazmat shipping papers
• [ ] Fire extinguisher charged and secured
• [ ] Three warning triangles
• [ ] Spare fuses if your vehicle requires them

Post-trip inspection and DVIR

At the end of the day, walk the truck again. Property-carrying drivers generally must complete a written or electronic driver vehicle inspection report (DVIR) when they find or are told about a defect that would affect safety or cause a breakdown. The carrier must repair or certify that repair is not needed before the vehicle is driven again, and the next driver reviews and signs. Many carriers require a DVIR every day regardless. Keep DVIRs as long as the rules require (generally three months). Confirm current requirements with FMCSA.

Hypothetical example: what a missed light costs

Say a marker light is out. Fixing it in the yard: a bulb and five minutes. Caught at a weigh station: a violation on your record and maybe an inspection that runs 45 minutes. If that pushes you past a delivery appointment, you could lose the load, pay a late fee, or burn hours you needed for the next pickup. On a hypothetical $1,800 load, missing the appointment can cost far more than the bulb.
