After a Roadside Inspection: The 24-Hour, 15-Day and 12-Month Rules

Updated September 2026

A roadside inspection ends with a piece of paper, and most of what the rules require happens after the officer has driven away. It is all in one section, 49 CFR 396.9.

Out of service means parked

An inspector who finds a vehicle likely to cause an accident or a breakdown because of its mechanical condition or loading declares it out of service. The rule is blunt: no carrier may "require or permit any person to operate" it until all the repairs required by the out-of-service notice have been satisfactorily completed (396.9(c)). Not "back to the yard carefully." Operating an out-of-service vehicle before it is repaired is one of the violations that fails a new-entrant audit on its own.

The driver's job: 24 hours

The driver must deliver the inspection report to the carrier on arrival at the next terminal or facility. If that will not happen within 24 hours, the driver has to mail, fax or otherwise send it to the carrier immediately (396.9(d)(1)).

A report that lives in the door pocket for a month has already broken the rule — and you cannot fix what you do not know about.

The carrier's job: fix it, and say so within 15 days

  1. Examine the report and correct the violations or defects noted on it (396.9(d)(2)).
  2. Within 15 days of the inspection, certify that all violations have been corrected — by completing the signature of carrier official, title and date on the form — and return it to the issuing agency at the address on the report (396.9(d)(3)).
  3. Keep a copy for 12 months from the date of the inspection, at your principal place of business or where the vehicle is housed.

A clean inspection is worth keeping too

An inspection with no violations still produces a report, and it is part of your inspection history. Treat it the same way: driver hands it in, you file it.

The habit that makes this easy

  • The driver photographs the report the same day and sends it in.
  • Every violation on it becomes a defect on that truck — written up, repaired, signed off — so the repair is on record before you sign the certification.
  • The 15-day date goes on a calendar the day the report arrives.
