The annual DOT inspection is a full inspection of every commercial motor vehicle, done at least once every 12 months by a qualified inspector against the standards in Appendix A to 49 CFR Part 396. It is separate from the driver's daily pre-trip, and it is the inspection that produces the report auditors ask for. This checklist covers the twelve sections of the standard with the numbers that decide pass or fail, the inspector qualifications, and the report fields to keep for 14 months. Schedule a call to put your annual inspection dates and reports in one place, or compare it with the daily pre-trip checklist.
ANNUAL DOT INSPECTIONS · SAFETY MANAGERS, SHOPS AND OWNER-OPERATORS
Twelve Months, One Report, Every Unit
An annual inspection only counts if it passed, was done by someone qualified, and can be shown on request. Here is the standard, the paperwork and the dates to track.
THE RULE AT A GLANCE
12
months between inspections, at most
1
inspection per unit, so a tractor and trailer need two
14
months to keep the report
When the Clock Runs Out
The 12 months run from the last day of the month the inspection was done, so a vehicle inspected on March 10, 2026 is covered through March 31, 2027. Use the month, not the day, when you set reminders. The example below is only an illustration.

Three Ways to Get It Done
IN-HOUSE
Your own qualified inspector
Allowed for most vehicles, if the person meets the inspector qualifications and you keep proof.
THIRD PARTY
A garage or fleet service
A commercial garage, leasing company or truck stop can act as your agent if it has the facilities and qualified inspectors.
STATE PROGRAM
A state periodic inspection
A passing state or equivalent program inspection counts, if it meets the federal minimums.

Who Is Allowed to Sign
A pass is only valid if the inspector is qualified under 49 CFR 396.19. Check these four before the inspection, not after. Read the qualification rule.

- Has a state or federal training certificate, or at least one year of combined training and experience
- Qualification proof is on file for as long as they inspect for you, plus one year
What the Report Must Contain
The report under 49 CFR 396.21 is what you hand to an auditor. Keep the original or a copy for 14 months where the vehicle is housed or maintained. Read the report rule.
- Name of the inspector
- Name of the motor carrier
- Inspection date
- Vehicle identification
- Components inspected and the result for each
- Any component below the Appendix A standard

Frequently Asked Questions
What is an annual DOT inspection?
A full inspection of a commercial motor vehicle, done at least once in the preceding 12 months, against the minimum standards in Appendix A to 49 CFR Part 396. Read 49 CFR 396.17.
Does every vehicle need its own inspection?
Yes. Each unit in a combination counts separately, so a tractor and a semitrailer need one inspection each, and a full trailer needs a third.
What proof must be on the vehicle?
Either the inspection report or a sticker or decal showing the inspection date, who keeps the report, vehicle identification and a certification that the vehicle passed.
Can the carrier do its own inspections?
Yes, if the inspector meets the qualifications in 396.19. A carrier may also use a garage or fleet service as its agent, or rely on a passing state periodic inspection that meets the federal minimums.
How long are annual inspection records kept?
The report is kept for 14 months, at the place the vehicle is housed or maintained. Inspector qualification records are kept for as long as the person inspects for you, plus one year.
Is an annual inspection PDF enough?
A PDF works as a report template, but it does not remind you of due dates or keep reports with the vehicle. A digital record does both. Schedule a call to see how it works. For more detail, read our annual inspection fleet guide.
What does FleetRabbit cost?
FleetRabbit is free for up to three vehicles and $5 per vehicle per month after that. Start tracking your inspection records free.
Pass It Once, Prove It for 14 Months
The inspection takes a day. The record has to last more than a year. Keep both in one place, with the due date set before the month runs out.
Free tier for up to 3 vehicles · No credit card required · Reports stored with due dates
