A DOT inspection form is a self-audit of one truck, its trailers and its driver against what a roadside inspector looks at — done by you, before an inspector does it for you. It runs in roughly the order a roadside inspection goes: the driver's documents, then the vehicle's paperwork, then a walk round the lights, brakes, tyres, coupling and load.

What happens at a DOT roadside inspection
In the US, roadside inspections of commercial motor vehicles are carried out by state enforcement officers following the Commercial Vehicle Safety Alliance's North American Standard procedure. Most inspections are one of three levels:
- Level I — the full inspection: the driver's documents, then the vehicle, including underneath.
- Level II — a walk-around: the driver's documents and everything that can be checked without getting under the vehicle.
- Level III — the driver only: licence, medical certificate, hours of service, and the papers the driver carries.
Out of service is the outcome to avoid
Violations are recorded either way, but a serious one under CVSA's out-of-service criteria stops the vehicle or the driver where they stand until it is put right — a tow, a mobile mechanic, a relief driver, a missed delivery. Violations also feed the carrier's safety record.
Year after year the same areas sit near the top of the violation lists: lamps that do not work, brakes out of adjustment, worn or damaged tyres, and hours-of-service records. Those get their own sections here, and they are worth checking first if time is short.
The driver half of the inspection
An inspector usually starts at the cab door. Before any tyre is looked at, the driver will be asked for a licence of the right class with the right endorsements for the load, a current medical certificate where the licence type requires one to be carried, and records of duty status for today and the previous seven days.
Drivers on an ELD should be able to display or transfer their logs on request — practise it, because "I don't know how" is a poor answer at a scale house — and should carry the device's user guide, the data-transfer instructions, the malfunction instructions and enough blank paper logs to cover an outage.
This is not the annual inspection
The yearly periodic inspection under 49 CFR 396.17 is a component-by-component examination by a qualified inspector, recorded in its own report. This form only asks whether that inspection is in date and its proof is on board; use the annual vehicle inspection form for the inspection itself.
Vehicles that pass a Level I or Level V inspection without critical violations can receive a CVSA decal, generally valid for up to three months, and inspectors often pass decaled vehicles by. This self-audit does not earn a decal, but it is the best way to be ready for the inspection that might.
Common questions
What do DOT inspectors check first?
Usually the driver: licence and endorsements, medical certificate, and hours-of-service records, then the vehicle's registration, its annual inspection proof and the last inspection report. The vehicle walk-around comes after.
How often should we run a DOT self-audit?
Common points are when a new driver starts, after any roadside inspection that found violations, ahead of the annual enforcement blitzes, and on a regular cycle per unit — monthly or quarterly. A spot check on a random truck tells you more than a scheduled one.
How much tread does a truck tyre need for a DOT inspection?
The federal equipment rule asks for at least 4/32 inch in every major groove on steer tyres and 2/32 inch on the others. The out-of-service thresholds are lower, but a tyre under the equipment minimum is still a violation on the record.
Is a DOT inspection the same as the annual inspection?
No. A roadside inspection is done by an enforcement officer at any time; the annual periodic inspection is done by your own qualified inspector or a shop once a year. A truck needs a current annual to pass a roadside inspection, which is why this form checks for it.
What emergency equipment must a truck carry?
Under 49 CFR 393.95, a properly rated fire extinguisher, securely mounted and charged — 5 B:C is the usual minimum, 10 B:C on placarded hazmat loads — and three bidirectional reflective warning triangles. Check the current rule for your vehicle; your company may require more.
Does passing this audit mean we will pass a roadside inspection?
No. It means you looked at the things inspectors look at and fixed what you found. An officer works to the out-of-service criteria current on the day, and can find things a self-audit missed.
