Carrier operations
Commercial Vehicle Inspections: Roadside, Annual and DVIR
Commercial vehicle inspections serve different jobs: the driver checks the vehicle before use, the carrier arranges periodic inspections and maintenance, and enforcement may examine the driver or vehicle on the road. Keep those tasks separate in your files. A roadside report is neither an annual inspection certificate nor a carrier safety rating.

Federal inspection and maintenance guidance for property-carrying commercial motor vehicles subject to the FMCSRs; state intrastate rules and specialized equipment need separate review.
Which inspection are you preparing for?
CVSA inspection levels you may encounter
The Commercial Vehicle Safety Alliance describes the scope of each North American inspection level. Ask which level was performed before interpreting a report. A credential inspection alone says little about the truck’s mechanical condition.
Driver checks and defect reports
Before taking the truck out, review unresolved defects and the required repair certification. The pre-trip duty to be satisfied the vehicle is safe remains even when a written no-defect report is not required.
Under the current federal DVIR rule, drivers do not need a report when no defect or deficiency is discovered or reported. Required defect reports must be signed; the carrier must repair safety-affecting defects and certify the disposition before the next operation. Keep the report and related certifications for 3 months.
Section 396.11 has exceptions, including a carrier operating only one commercial motor vehicle, a driveaway-towaway operation and a nonbusiness private passenger carrier. An exception to this report does not eliminate other inspection or safe-operation duties. Intermodal equipment has separate reporting provisions.
Annual inspection and maintenance files
Check the truck and trailer records separately. A passing periodic inspection needs the documentation specified by section 396.17; an ordinary roadside report alone does not establish that the periodic requirements were met.
Keep the periodic inspection report for 14 months. Its contents identify the inspector, carrier, vehicle, date, items inspected and results, with the required certification.
FMCSA’s maintenance-record guidance calls for a vehicle identity record, a schedule of work due, and dated inspection, repair and maintenance history for vehicles controlled for at least 30 consecutive days. Retain those records for one year where the vehicle is housed or maintained, and for six months after it leaves the carrier’s control.
Build a folder for each unit with its inspection record at the front. Put repair invoices behind the defect they resolved so someone else can follow the sequence without asking the driver to reconstruct it.
After a roadside inspection
A vehicle marked out of service cannot operate until the repairs required by that notice are completed. The report also needs carrier review and correction of its violations. Within 15 days, certify the corrections; return the form if the issuing state requests it, and retain a copy for 12 months.
Do not treat the paperwork deadline as permission to keep driving an unsafe vehicle. Give the report to the carrier promptly, identify the repair owner and preserve the evidence of the fix. Follow the instructions on the actual notice.
- Read the vehicle and driver identifiers and the inspection level.
- Separate conditions that prohibit operation from administrative follow-up.
- Assign each defect to a person who can arrange and document the repair.
- Check whether the issuing agency requests the completed form back.
- File the original report with the corrections and any follow-up correspondence.
Keep inspections separate from audits and ratings
A new-entrant safety audit examines the carrier’s safety-management practices and records. Roadside inspection history is a different record, and a single clean inspection does not create a Satisfactory safety rating. Use the lookup guide to read the actual field labels and the audit guide to prepare the carrier files.
Frequently asked questions
Does a roadside inspection replace my annual inspection?
- Do not assume it does. The periodic inspection has its own scope and documentation requirements. Check the actual periodic report for each vehicle in the combination.
Must I write a DVIR when nothing is wrong?
- The current federal rule does not require a no-defect report. Required defect reports, repair certifications and applicable exceptions are described above; safe-operation and pre-trip duties still apply.
