The Pre-Trip Inspection, Item by Item: What the Driver Checks and What You Have to Keep

Updated September 2026

Ask ten small-fleet owners what the pre-trip rule requires and you'll get ten answers, most of them stricter or looser than the rule itself. It is actually two short rules that work together — one about looking at the truck before driving it, one about writing down what's wrong with it at the end of the day.

Here is what each one says, with the section number so you can read it yourself.

Before driving: be satisfied the truck is safe

Before driving, the driver has to be satisfied that the vehicle is in safe operating condition (49 CFR 396.13). A separate rule, 49 CFR 392.7, says a commercial motor vehicle may not be driven unless the driver is satisfied that these parts and accessories are in good working order:

  • Service brakes, including trailer brake connections
  • Parking (hand) brake
  • Steering mechanism
  • Lighting devices and reflectors
  • Tires
  • Horn
  • Windshield wiper or wipers
  • Rear-vision mirror or mirrors
  • Coupling devices
  • Wheels and rims
  • Emergency equipment

That is the list — eleven items. Notice what the rule does not say: it doesn't require a written pre-trip form. It requires the driver to actually be satisfied. Many carriers have the driver record a pre-trip anyway, because "I looked at it" is hard to show later and a dated record is not.

If the last inspection report listed a defect, the driver also has to review that report before driving, and sign it to acknowledge that the repair was certified (396.13(b) and (c)).

After the day's work: the written report

The written report — the DVIR — belongs to the end of the day. Under 49 CFR 396.11, the driver prepares a report at the completion of each day's work on each vehicle operated, covering the same eleven items.

The report has to identify the vehicle, list any defect or deficiency that would affect safe operation or cause a breakdown, and be signed by the driver.

Here is the part that surprises people: "Drivers are not required to prepare a report if no defect or deficiency is discovered by or reported to the driver." Under the federal rule for property-carrying vehicles, a day with nothing wrong needs no written report. Logging one every day is a choice — a common one, because a gap in the record looks the same as a skipped inspection to anyone reading it later.

When a defect is written up

Before the vehicle goes out again, the carrier has to (396.11(a)(3)):

  1. Repair any listed defect that would be likely to affect the safety of operation.
  2. Certify on the report that the defect has been repaired, or that repair is unnecessary before the vehicle is operated again.

Then the next driver reviews that report and signs it (396.13). That chain — defect written up, repair certified, next driver's acknowledgement — is what someone reviewing your records is looking for. Failing to correct documented defects is also on the short list of violations that fail a new-entrant safety audit outright (49 CFR 385.321).

How long to keep it

Three months. The carrier keeps the inspection report, the certification of repairs, and the next driver's acknowledgement for three months from the date the report was prepared (396.11(a)(4)). The reports may be created and kept electronically (396.13(d), referring to 49 CFR 390.32).

The exception for one-truck operations

The written-report rule in 396.11 does not apply to "a motor carrier operating only one commercial motor vehicle," nor to driveaway-towaway operations or private (nonbusiness) passenger carriers (396.11(a)(5)).

If you run a single truck, the end-of-day DVIR paperwork isn't required of you under this federal rule. The duty to be satisfied the truck is safe before driving it (392.7, 396.13) still is, and so are the maintenance record rules in the rest of Part 396. The day you put a second truck on the road, the report rule applies.

What this looks like in a small fleet

  • Make the pre-trip the way in to the day's work. A check that has to happen before the job list opens gets done; a form that can be filled in later gets filled in later.
  • Photograph the truck. The rules don't require photos. But four corners and the odometer, dated, answer most "was it like that this morning?" arguments.
  • Close the loop on defects. A defect with no recorded outcome is worse than no record at all. Write down who fixed it, when, or why it was safe to run.
  • Keep it where you can find it by truck and by date. Three months isn't long — but the request will be for one truck, for one week.
