A quarry haul truck that skips its pre-shift inspection is a liability waiting to happen, brake fade on a loaded descent, a blown tire on an uneven bench, or a steering fault near an active blast zone. MSHA doesn't treat this as optional paperwork, it's a daily legal requirement under 30 CFR, and a missed defect on record is the first thing an inspector checks after an incident. Sign up to move this checklist off paper and into a system that timestamps every inspection and flags every defect automatically.
Why It Matters
MSHA requires a documented pre-shift examination of every haul truck before it moves a single load. The check isn't just brakes and tires, it's steering response, lighting, backup alarms, fire suppression, and the seatbelt the operator is trusting their life to. A skipped item on a paper form is invisible until it fails on the haul road.
Six Systems Every Inspection Must Cover
Brakes
Service, park, and retarder tested before the truck leaves the shop
Tires & Rims
Pressure, cuts, chunking, and rim cracks checked cold, before load
Lights & Alarms
Headlights, tail lights, backup alarm, and strobe all functional
Steering
No excessive play, fluid level correct, no leaks at the cylinder
Safety Devices
Seatbelt, fire suppression, and grab handles present and secure
Fluid Leaks
Ground checked under the truck for fuel, hydraulic, or coolant drips
The Pre-Shift Walkaround, In Order
Walk the perimeter first: check for fresh fluid under the truck before the engine has run and masked a leak
Inspect tires cold: check pressure, sidewall cuts, and rim cracks before the truck moves and heat builds
Test brakes in the bay: service and park brake response checked at low speed, never on the haul road
Confirm all lighting: headlights, tail lights, strobe, and backup alarm cycled on before entering the pit
Check the cab: seatbelt, mirrors, horn, and fire suppression pin all present and intact
Log every defect immediately: a tagged-out truck stays parked until the defect is corrected and signed off
Turn Paper Checklists Into MSHA-Ready Records
OxMaint puts this checklist on the operator's phone, timestamps every inspection, and auto-generates a work order the second a defect is logged. Sign up for a free trial to run it on your own fleet, or book a demo to see it configured for your quarry.
Common Defects And What They Mean
| Component |
Common Defect |
Required Action |
| Brakes |
Spongy pedal, retarder lag, air pressure loss |
Tag out immediately, no exceptions |
| Tires |
Sidewall cut, chunking, low pressure |
Tag out, replace or re-inflate before dispatch |
| Steering |
Excess play, fluid leak at cylinder |
Tag out immediately, no exceptions |
| Lights & Alarms |
Dead bulb, silent backup alarm |
Correct before shift, restricted travel until fixed |
The Takeaway
A pre-shift inspection is only as reliable as its record. Paper forms get lost, defects go unreported, and MSHA has no way to verify the check happened. A digital checklist with a timestamp and a photo turns compliance from a guess into proof.
Frequently Asked Questions
Q
Is a pre-shift haul truck inspection legally required by MSHA?
Yes. MSHA requires a documented examination of mobile equipment before it's placed into service each shift, and any defect affecting safety must be corrected before the truck is used or the truck must be tagged out.
Q
What happens if a defect is found during inspection?
Any defect that affects safety, brakes, steering, or lighting, requires the truck to be tagged out and removed from service until it's repaired and re-inspected. Minor defects can be logged for scheduled correction, but must still be recorded.
Q
How long do inspection records need to be kept?
MSHA generally requires equipment examination records to be retained for at least one year and made available for inspection on request. Digital records with timestamps make this far easier to produce during an audit than paper logs.
