The fleet manager’s guide to fleet maintenance documentation

By Jennifer Coreno Strouth March 19, 2026

Today’s business margins are razor thin. For fleets, profitability often comes down to what is or isn't on paper. The best fleet managers know that documentation, when used correctly, can be a major advantage — and fleet maintenance records can help you save time and money.

A good maintenance documentation strategy helps you reap profits in two big ways: asset uptime and reducing total cost of ownership (TCO). To achieve this, fleets are now implementing a new maintenance document management process: the closed-loop workflow.

In a traditional strategy, if a driver notes a soft brake pedal, they file a report and hope that it will get fixed in due time. In a closed-loop system, fleet maintenance tracking software uses digital documentation to proactively address issues that keep vehicles healthy, support driver safety and boost uptime. The loop starts when a driver spots an issue that triggers a fix, which is then verified by a driver or manager, closing the loop.

The proof that this method works is in the cost savings: According to the Fleet Technology Trends Report, organizations using fleet management software like this save an average of 15% in maintenance costs annually.¹

What fleet maintenance records are required by the DOT and FMCSA?

The Federal Motor Carrier Safety Administration (FMCSA) mandates that motor carriers "must systematically inspect, repair, and maintain all motor vehicles and intermodal equipment subject to its control." To remain compliant with Department of Transportation (DOT) record-keeping requirements, your files must include:

Vehicle identification: Company number, make, vehicle identification number (VIN), year and tire size.
Maintenance schedule: A clear record of all upcoming inspections and maintenance tasks.
Repair history: A chronological record of all inspections, repairs and maintenance performed, including the date and specific nature of the work.

Failing to maintain these records can come at a steep cost. During the recent Commercial Vehicle Safety Alliance’s (CVSA) 72-hour International Roadcheck inspection, 13,553 out-of-service vehicle violations were discovered and 10,148 vehicles were placed out of service.²

There are also strict retention requirements for fleets, meaning they often must keep fleet maintenance records for an extended time period. Understanding how long to keep these records is just as vital as creating them, as misplacing a file for a vehicle sold months ago can still trigger a "critical violation" during a carrier investigation.

How long do you need to keep DOT maintenance records? Remember the "1&6 Rule":

1 Year: Records must be retained for at least one year while the vehicle is in your active control.
6 Months: If a vehicle leaves your fleet (sold, traded, or scrapped), you must retain its records for an additional six months after the date of disposition.³

Paper logs are easily damaged or lost, but fleet maintenance tracking software retains a vehicle’s entire history — and it’s searchable within seconds if you find yourself in a surprise audit.

The benefits of DVIRs and digital maintenance data documentation

The tool you use to capture data is just as important as the data itself. Switching from paper driver vehicle inspection reports (DVIRs) to electronic DVIRs and digital fleet maintenance records is far easier for fleet maintenance tracking for a number of reasons.

Streamlined inspections and accuracy: DVIRs remove the friction of manual paperwork. Drivers no longer need to hunt for the right form or a working pen; they simply use an app on their mobile device. Another big risk of paper-based fleet maintenance records is technicians or drivers checking boxes without actually performing the inspection – a risk eliminated by electronic DVIR forms.
Speedy repair turnaround: When a driver flags a critical defect, the report can be routed to your service department or even a third-party maintenance provider with the right API integrations. Additionally, by including photos with the digital report, technicians can investigate and isolate faults before the truck even hits the yard, drastically reducing downtime.
Customized compliance: Not every asset is the same. DVIRs using a telematics solution allow you to create customized inspection forms for specialized equipment (EVs, powered assets like backhoes and cranes, for example) so drivers see only the fields relevant to that vehicle or equipment.
Simplified auditing: Federal regulations require carriers to keep at least three months of DVIRs available for immediate review.³ Cloud-based software allows you to store and retrieve these records instantly from anywhere, ensuring you are always prepared for a surprise FMCSA audit.
Telematics-driven maintenance scheduling: Fixed service intervals like "every 3,000 miles" do not account for actual usage. For more accurate servicing, use telematics data that reflects real-world usage like mileage and engine hours. Receive automated alerts based on this data so you can stay ahead of service needs and reduce unplanned repairs.

See it in action: Here’s how one company was able to transform their fleet maintenance efforts with the right technology.

When Midwest Respiratory and Rehab needed to give its routine vehicle inspections a digital makeover, they turned to Verizon Connect. Their old process using paper-based DVIRs had eaten up hours of administrative time. That all changed when they switched to a fleet tracking maintenance system.

"If you have something wrong with the truck — let's say your windshield got hit by a rock — all you have to do is click on 'windshield,' choose 'hit by rock,' snap a picture of it, and you're done," Patrick Fisher, regional operations manager at Midwest Respiratory and Rehab said. "The simplicity of the form and the easiness of the app probably cuts out 30-45 minutes a day. It is literally the easiest thing to use that I have seen. That would put us on pace to save over 100 hours in a year."

Compliance is critical, but it doesn’t have to be complicated. The right solutions can keep your fleet on track. Here’s our guide.

Bridging DVIRs to shop orders: The closed-loop workflow

A closed-loop workflow driven by fleet maintenance tracking software is one of the best practices for documenting work order completion for compliance and safety. It operates in three key steps.

Step 1: The defect trigger

The loop starts with your daily DVIRs. Under 49 CFR 396.11, drivers must report "any defect that would affect the safety of operation." When an inspection item is marked as critical (like a cracked windshield), and the driver marks a status of "fail" or "needs attention" on the DVIR, the system can automatically generate a pending maintenance event. This removes human error and ensures the "spokes" of the wheel always point to where the repair needs to occur.

Step 2: The work order

Once a failed DVIR triggers a work order, it’s important to document the resolution with detail in case of an audit. Here are some of the data points your records should include:

Technician ID/name: Who performed the work or made the "repair unnecessary" determination.
Parts used: A list of components replaced.
Labor hours: Proof of the time invested.
Date of completion: This must align with the date the vehicle was returned to service.

Step 3: The auto repair certification

This step is where most fleets will fail their audits. FMCSA regulations require a specific "certification of repairs." ³ It isn't enough to perform the task needed to fix a vehicle or piece of equipment — you must also verify it.

This requires a three-part signature chain:

The driver's signature on the original report that flagged the defect.
The mechanic’s certification that the repair has been made or was unnecessary.
The next driver to operate the vehicle must sign the DVIR to acknowledge that they have reviewed the repair certification and that the vehicle is safe to drive.

Closing the loop with that next inspection proves to governing bodies that your fleet enables you to fully resolve or repair any issues before the vehicle is back on the road.

Managing specialized documentation for mixed fleets

As modern fleets diversify to meet sustainability goals, the "one-size-fits-all" maintenance system just won’t work anymore. Managing a mixed fleet that combines traditional Internal Combustion Engines (ICE) with Electric Vehicles (EV) or other specialized powered assets requires a segmented documentation strategy to ensure each vehicle remains compliant with its specific regulatory and mechanical needs. Here are some things to consider:

CARB Compliance: The CARB program – the Clean Truck Check program, also known as the Heavy-Duty Inspection and Maintenance Program – specifically targets reducing emissions from heavy-duty vehicles. For fleets operating in or through California, all compliance deadlines require a passing emissions test to be submitted to the CARB Information System (CTC-VIS).
EV specifics: Utilizing EVs in your fleet doesn't mean less maintenance or documentation — it’s just different from ICE vehicles. You aren't tracking oil changes or exhaust systems, but you are tracking the battery. Documenting battery degradation and coolant levels for the battery pack is essential for long-term TCO and warranty claims.
Vendor management: Even if you outsource your maintenance to a local shop or dealer, you are legally responsible for the documentation. If a vendor’s invoice just says "service performed," your fleet is at risk during an audit. Every invoice should include the technician's certification and a clear breakdown of parts and labor.

Fleet maintenance documentation has officially moved from a back-office burden to a frontline strategy. The shift toward a closed-loop, predictive workflow helps keep your fleet compliant while also protecting your bottom line. According to the Fleet Technology Trends Report, 26% of GPS fleet tracking users said the technology helped them achieve their regulatory compliance goals.¹

Maintenance documentation is the one "source of truth" across your entire organization. By closing the loop between inspections, reports and repair technicians — while getting ahead of and fueling that cycle with predictive data — your fleet stays compliant, your drivers stay safer and your assets remain profitable long into the future.
