But beyond the inspections themselves, proper documentation is just as crucial. Without an up-to-date DOT vehicle maintenance file, fleets can face costly penalties, unexpected audits, and even increased insurance premiums.

So, how do you ensure your records are compliant and organized? This guide will walk you through everything you need to know about DOT vehicle maintenance files, including:

• What the FMCSA vehicle maintenance file is and why it matters
• Who needs to maintain these records
• How long you should keep them
• A complete checklist to ensure compliance
• Best practices to streamline your record-keeping process

A missing document or an outdated file could put your fleet—and your business—at risk. Let’s break down exactly what you need to know to stay compliant and keep your trucks on the road.

What Is the FMCSA Vehicle Maintenance File?

A DOT vehicle maintenance file is more than just a collection of service records—it’s a critical part of regulatory compliance for motor carriers. The Federal Motor Carrier Safety Administration (FMCSA) requires fleets to systematically inspect, repair, and maintain their commercial motor vehicles under 49 CFR 396. This regulation ensures that all commercial vehicles remain safe and roadworthy, reducing the risk of mechanical failures that could lead to accidents, fines, or vehicle downtime.

Why Does FMCSA Require Fleets to Maintain These Records?

The FMCSA enforces strict maintenance record requirements for two key reasons:

1. Safety & Compliance

Regular inspections and repairs help prevent vehicle malfunctions that could cause accidents or put drivers at risk.

1. Accountability 

A well-documented maintenance history ensures fleets can demonstrate compliance in the event of an audit, inspection, or legal issue.

The Impact of Incomplete or Missing Records

Failure to maintain a properly documented vehicle maintenance file can have serious consequences, including:

• Costly fines and violations: Missing records can result in FMCSA citations, with penalties that can quickly add up.
• Increased risk of audits: Incomplete maintenance files can trigger more frequent DOT audits and inspections.
• Higher insurance rates: Poor maintenance records can make a fleet appear riskier to insurers, leading to increased premiums.
• Potential out-of-service orders: If a vehicle is found to be out of compliance, it could be pulled from service until repairs and documentation are completed.

To stay compliant and keep your trucks on the road, every fleet operator must understand who is required to maintain these records and how long they need to be kept.

Who Needs to Keep a DOT Vehicle Maintenance File?

DOT vehicle maintenance file requirements apply to a wide range of commercial fleets, including:

• Trucking companies: Both for-hire carriers and private fleets.
• Fleet operators: Businesses that operate commercial vehicles as part of their operations.
• Commercial carriers: Any company transporting goods or passengers in regulated vehicles.

Which Vehicles Require Maintenance Files?

FMCSA regulations state that any commercial motor vehicle (CMV) with a gross vehicle weight rating (GVWR) of 10,001 pounds or more must have a vehicle maintenance file. This includes:

• Semi-trucks and trailers
• Box trucks and delivery vehicles
• Passenger carriers (buses, shuttle vans)
• Heavy-duty service vehicles

If your business operates vehicles that fall under FMCSA regulations, maintaining a proper vehicle maintenance file is mandatory. But how long should these records be kept?

How Long Should You Keep Maintenance Records?

The FMCSA requires motor carriers to retain most vehicle maintenance records for at least one year while the vehicle is in service and for at least six months after it leaves the fleet. However, some records may need to be kept longer for warranty purposes, internal audits, or legal protection.

Best Practices for Recordkeeping

To ensure compliance and avoid costly audits, follow these recordkeeping best practices:

• Digitize your records: Use a fleet management system to store and organize maintenance files electronically.
• Keep inspection and repair logs up to date: Ensure that all maintenance records are accurate and easily accessible.
