Heavy Vehicle Inspection (Weekly) is where safety programs either hold up under audit or fall apart — and a daily walkaround alone doesn't catch everything a weekly deep-check does. Sign up to run your weekly heavy vehicle inspections digitally, with photo evidence and a full audit trail behind every result.
What This Guide Covers
This guide walks through a complete weekly heavy vehicle inspection procedure, aligned to FMCSA 396: what a weekly check adds beyond the daily walkaround, clear pass/fail criteria for each component, mandatory documentation points, and the corrective-action workflow auditors expect to see.
Why A Weekly Check Is Different From A Daily One
| Check Type |
Depth Of Inspection |
| Daily walkaround |
Fast visual and operational check — lights, tires, leaks, and basic brake function |
| Weekly inspection |
Deeper measurement-based check — brake lining thickness, suspension components, frame, and undercarriage |
| Annual DOT inspection |
Full regulated inspection by a qualified inspector against every FMCSA 396.17 item |
What The Weekly Inspection Covers
Brake Components
Lining thickness, chamber stroke, and slack adjuster travel measured against limits
Suspension & Frame
Cracked springs, loose U-bolts, and frame rust or damage checked under the vehicle
Drivetrain
Driveshaft play, U-joints, and differential fluid level and leaks
Coupling & Cargo Securement
Fifth wheel wear, kingpin condition, and trailer connection integrity

Running The Weekly Inspection In Order
01
Get The Vehicle On A Lift Or Pit
Undercarriage items like frame, springs, and driveshaft can't be verified from ground level
02
Measure, Don't Estimate
Brake lining thickness and stroke get a gauge, not a glance, since both determine service life
03
Photo Every Component Near Its Limit
A worn kingpin or a hairline frame crack gets documented now, before it becomes a failure later
04
Close The Loop With A Work Order
Anything below threshold generates a repair task immediately, linked back to this week's inspection
Skipping A Week Doesn't Show Up Until It Does
A brake lining that was fine two weeks ago can be past its limit today. Fleets that skip a weekly cycle under time pressure are the ones most likely to discover the gap during a roadside inspection instead of their own shop.
Frequently Asked Questions
Q
Does a weekly inspection replace the annual DOT inspection?
No, the weekly inspection is an internal preventive check. It doesn't substitute for the annual inspection required under FMCSA 396.17, though it does reduce the chance of failing it.
Q
Who should perform the weekly inspection?
A technician trained on brake and suspension measurement should run it, since several checks require a gauge reading rather than a visual pass or fail.
Q
What happens if a vehicle misses its scheduled weekly inspection?
Most fleets flag the vehicle and hold it from dispatch until the inspection is completed, since a missed cycle breaks the compliance record auditors look for.
