If your records are a mess, you’re looking at fines that can wipe out a month’s profit—or worse, an “Unsatisfactory” rating that grounds your truck. Here is exactly what you need to keep, how long to keep it, and how to organize it so you can pass an audit without breaking a sweat.

1. The Driver Qualification (DQ) File

Since you’re the owner and the driver, you have to maintain a DQ file on yourself. This is the #1 thing auditors look at.

What’s inside:

• Driver Application: Yes, even for yourself.
• MVR (Motor Vehicle Record): You need the initial one from when you started and an annual review thereafter.
• Certificate of Road Test: Or a copy of your CDL (if it meets the requirements).
• Medical Examiner’s Certificate (Med Card): Keep the current one and the previous one.
• Annual List of Violations: A document you sign once a year listing any tickets (even if it’s “none”).

Retention: Keep these for as long as you’re driving, plus 3 years after you stop.

So basically, if you can’t hand this folder over immediately, you’re already behind. Many owner-operators use FMCSA compliance tools to keep these records organized and verifiable so nothing slips through the cracks.

2. Drug & Alcohol Clearinghouse Records

You can’t just say you’re clean; you have to prove you’re in a testing program.

What to keep:

• The Consortium: As an owner-operator, you must be enrolled in a random testing pool (Consortium). Keep your enrollment certificate handy.
• Queries: You must run a “Full Query” on yourself in the FMCSA Clearinghouse once a year. Print the result and file it.

Retention: Keep records of test results and annual queries for 5 years.

3. Hours of Service (HOS) and ELD Records

This is where most guys get tripped up. It’s not just the logs; it’s the supporting documents.

What to keep:

• The Logs: Your ELD handles the 6-month history, but you should download a backup monthly.
• Supporting Docs: These are “breadcrumbs” that prove your logs are honest. This includes fuel receipts, toll receipts, gate passes, and dispatch records.

Retention: You must keep logs and supporting documents for 6 months.

4. Vehicle Maintenance Files

If the truck isn’t safe, you aren’t moving. The DOT wants to see a paper trail for every bolt you tightened.

What to keep:

• Identification: A sheet listing the VIN, year, make, and tire size.
• Periodic Inspection: Your annual DOT inspection (the “sticker” paperwork).
• Maintenance Records: Every oil change, brake job, and repair. If you did it yourself, keep the receipts for the parts.
• DVIRs: Daily Vehicle Inspection Reports. You only need to keep these if a defect was found and repaired.

Retention: Keep maintenance records for 1 year while the equipment is in service, and 6 months after it leaves your fleet.

5. Accident Register

Even if you’ve had zero accidents, you need a folder labeled “Accident Register.” If an officer asks for it and you don’t have it, that’s a failure to maintain violation.

What to track:

• Date
• City
• State
• Driver name
• Whether there were injuries or a tow-away

Retention: Keep for 3 years.
