Maintenance and DVIR: What Paperwork You Actually Need to Keep

One conversation will reveal how confused most new carriers are about maintenance paperwork: a driver says, “I need to file a DVIR every day, right?” The answer is no—and that misconception costs drivers time and creates unnecessary paperwork.

Let’s clear it up.

The DVIR: What It Actually Is

A DVIR (Driver Vehicle Inspection Report) is a written report your driver must prepare at the end of each day’s work that identifies any defect affecting safety or that could cause a breakdown.

The legal requirement is in 49 CFR §396.11.

The Big Myth: “No-Defect DVIRs Are Required Daily”

Before 2014, no-defect reports were legally required every day—carriers had to document “no defects found” whether or not anything was actually wrong.

That rule changed. For property-carrying CMVs (which includes most small carriers), no-defect DVIRs are not required. Your driver only files a DVIR when defects actually exist.

If your truck has no problems today, you don’t file anything. This is a massive relief for small operations and a common source of confusion among drivers who learned the old standard.

DVIR Format and Medium

DVIRs can be:

Handwritten on paper
Completed electronically

Both are legally equivalent. As of March 23, 2026, electronic DVIRs are explicitly clarified in federal guidance, so digital tools and forms are fully compliant.

What to Include (When You File)

When a defect does exist, the DVIR must identify:

The specific defect
How it affects safety or could cause a breakdown
The date and vehicle identification

Example: “Brake pads worn past minimum thickness—unsafe to operate. Repair needed before next run.”

DVIR Retention: 90 Days

Keep DVIRs (and any repair certifications or driver review notes) for 3 months (90 days) from the date of the report. After that, you can discard them.

This is significantly shorter than other maintenance records, so don’t mistake DVIR retention for overall maintenance filing.

Annual Truck Inspection

Every CMV must pass a full safety inspection at least once every 12 months. This inspection covers all the components listed in Appendix A of Part 396—brakes, lights, steering, tires, coupling devices, and more.

The legal requirement is in 49 CFR §396.17.

What Gets Inspected

The inspection is comprehensive: exterior lighting, brakes (parking, service, emergency), steering, tires, coupling devices, mirrors, wipers, horn, and structural integrity. It’s a thorough checklist designed to catch anything that could fail on the road.

Inspection Documentation

You must keep a copy of the inspection report on the vehicle. This is what DOT will ask for at a roadside stop.

Additional records (repairs made as a result of the inspection, for example) can be kept in your office or shop—they don’t have to travel with the truck.

Inspection Retention: 14 Months

Keep the inspection report for 14 months from the report date. This is longer than DVIR retention because inspections are the baseline safety record for your entire fleet.

Written Maintenance Program

Beyond the DVIR and annual inspection, federal regulations require a written maintenance program (49 CFR §396.11). This is where small carriers often fall short.

Your written program must document:

Scheduled maintenance tracking: A record for each vehicle showing what maintenance is due and when (e.g., oil change every 10,000 miles, brake inspection annually, etc.).
Maintenance performed: Actual records of work done, including the date, vehicle, and nature of the work (e.g., “6/15/26 — Oil and filter change — Mileage: 45,200”).

This doesn’t have to be fancy. A spreadsheet works. A maintenance log in your fleet-management software works. What matters is that an auditor can open your files and see that you have a system and that you’re following it.

Maintenance Program Retention: 12 Months

Keep your maintenance records (scheduled and performed) for 12 months.

The Retention Table: Don’t Mix These Up

Document	Retention Period	What It Covers
DVIR	90 days	Defect reports filed when problems exist
Written Maintenance Program	12 months	Tracking what’s due + records of work done
Annual Inspection Report	14 months	Full vehicle safety inspection, kept on truck

These three retention periods are the biggest trip-up point in maintenance compliance. Don’t assume everything is 12 months or 90 days—they’re different for a reason.

How Maintenance Records Fail Audits

Maintenance is one of the top reasons carriers fail DOT audits. Here’s why:

Missing inspection reports: You didn’t do the annual inspection, or you did it but didn’t document it.

No DVIR process: You don’t have a system for drivers to report defects, so there’s no record of what was actually inspected.

No written maintenance program: There’s no evidence of scheduled maintenance—you’re just fixing trucks when they break instead of staying ahead of problems.

Incomplete repair records: You have DVIRs, but the repair work that followed isn’t documented. If a driver reported brake wear, you need to show that you fixed it.

The fix: set up a simple system now and stick to it. One spreadsheet tracking scheduled maintenance, one folder for completed DVIRs, and one folder for annual inspection reports will cover you.

Practical Steps to Get Compliant

Create a DVIR template (paper or digital) and put it in every truck. Explain to your drivers that they only file it if there’s a problem.
Schedule annual inspections before your authority goes active. Book them for the same month every year (e.g., July inspection date every July) so you never forget.
Build a maintenance log with columns for: vehicle, date, mileage, work performed, and cost. Update it as work is done.
Set a calendar reminder for 90-day DVIR purges and 12-month maintenance log archival. Don’t keep things forever—follow the rules and delete on schedule.
Keep the 14-month inspection report on the truck and a backup in your office. Print it, laminate it if you need to, but have it accessible.

Staying Ahead of Defects

The DVIR isn’t just paperwork—it’s your early warning system. A driver who reports brake wear in a DVIR gives you time to fix it. A driver who ignores it might trigger an alert at a DOT roadside inspection.

The best carriers create a culture where drivers feel they can report problems without punishment. If you penalize a driver for reporting a defect, they’ll stop reporting, and that’s when big problems start.
