When you run under your own authority, you are two people at once: the driver, and the carrier responsible for the carrier's paperwork. Federal rules do not shrink because the company is one truck. This DOT compliance checklist covers the big categories most one-truck, for-hire interstate operations need to have squared away, in the order an auditor tends to care about them. What running it looks like with the paperwork handled is on DOT compliance for owner-operators.
1. Your driver qualification (DQ) file: yes, on yourself
As the carrier, you must keep a qualification file on every driver of a commercial motor vehicle, including you (49 CFR 391.51). The core contents include your employment application, motor vehicle record checks (at hire and then annually), your road test certificate or the CDL accepted in its place, and your current medical examiner's certificate. Keep it as a real file, paper or digital, that you could hand over if asked; the driver qualification file checklist lists every item.
2. Drug & alcohol program enrollment
CDL operations require a DOT drug and alcohol testing program: a pre-employment test before driving, plus enrollment in a random testing pool. Owner-operators cannot run their own pool. You join a consortium (a shared random pool run by a third party). Keep your enrollment certificate and test records with your compliance files. How a drug consortium for owner-operators selects drivers, and what membership costs, has its own guide.
3. Clearinghouse registration and queries
The FMCSA Drug & Alcohol Clearinghouse is a federal database employers must check. Owner-operators are required to register, designate a consortium/third-party administrator (C/TPA), and make sure the required queries happen: a full query before a new CDL driver starts, and at least one query per year for every current CDL driver, including yourself. The registration itself, step by step, is in Clearinghouse registration for owner-operators.
4. Medical certificate: current, and on file
Your DOT medical card is valid for up to 24 months (examiners can certify for less). A lapsed card is one of the most common quiet violations in trucking, because the date passes silently. Track it with more than memory, and keep the current certificate in your DQ file.
5. Vehicle inspection and maintenance records
Each truck needs a current periodic (annual) inspection and a maintenance record trail. Keep the annual inspection documentation and your repair records organized by vehicle. When you get a roadside inspection report, keep it, some reports require you to certify repairs within a set window.
6. Registrations on a calendar
- MCS-150 biennial update, required every two years even if nothing changed; the filing month follows your USDOT number. Missing it can bring civil penalties, and the rule's stated consequence, deactivation of the number, has been paused by FMCSA since June 1, 2026 while carriers move onto Motus; the update is still required.
- UCR, the annual Unified Carrier Registration fee for interstate carriers, set by fleet size.
- IRP / IFTA credentials, apportioned plates and your fuel-tax license, renewed on their own cycles.
- Insurance filings, keep your required coverage active; a lapse can trigger revocation proceedings for your authority.
7. IFTA quarterly filings
If you are IFTA-registered, a fuel tax return is due every quarter, generally by the last day of the month after the quarter ends (April 30, July 31, October 31, January 31); when that day falls on a Saturday, Sunday, or legal holiday, the due date is the next business day (IFTA Articles of Agreement, R960.100). The return reconciles miles per state against fuel purchased per state, so save fuel receipts and keep your ELD mileage exportable.
8. The new-entrant window
New carriers go through FMCSA's new-entrant program, which includes a safety audit during your initial months of operation. The carriers that pass comfortably are the ones whose files above were organized before the audit was scheduled; the audit largely checks that these records exist and hold together. If your authority is brand new, the new authority checklist puts the first filings in order.
The whole DOT compliance checklist, on one page
The same list, short enough to print and keep with your records. The rule behind each item is in brackets; the download near the top of this page is this list as a one-page PDF.
Your authority and registrations
- USDOT number and operating authority active, with the insurance filing and BOC-3 on file (Parts 365, 366, 387)
- UCR registered and paid for the current year at ucr.gov (49 CFR 367.50)
- MCS-150 updated on its 24-month schedule, and whenever your operation changes (§ 390.19T)
- IFTA license and decals, and IRP plates, if the truck is over 26,000 pounds or has three or more axles and runs in two or more jurisdictions (IFTA R245, R305)
- Form 2290 filed and the stamped Schedule 1 kept, if the truck is 55,000 pounds or more (IRS Form 2290)
Your own driver file (you are the carrier and the driver)
- A driver qualification file on yourself, with the annual motor vehicle record and your review of it (§ 391.51)
- Medical certificate current, with the National Registry verification note (§ 391.43, § 391.23(m))
- CDL valid for the class and endorsements of what you drive (§ 383.23)
Drug and alcohol
- Enrolled in a consortium with a random testing pool (§ 382.115, § 382.305)
- A verified negative pre-employment drug test before your first load (§ 382.301)
- Registered in the Clearinghouse, a C/TPA designated, the pre-employment full query and the annual query run (§ 382.701)
The truck and the logs
- Periodic inspection within the last 12 months, with the documentation on the truck (§ 396.17)
- A maintenance file for the truck, and any defect reported on an inspection report repaired and certified (§ 396.3, § 396.11)
- Records of duty status on a registered ELD, unless an exception applies (§ 395.8)
The calendar
- IFTA returns: April 30, July 31, October 31, January 31 (next business day on a weekend or holiday)
- UCR for next year between October 1 and December 31
- Medical card, annual MVR and review, annual Clearinghouse query and annual inspection, each on its own anniversary
Put dates on everything
Almost everything on this list expires or renews: medical card, annual MVR pull, annual inspection, annual Clearinghouse query, quarterly IFTA, biennial MCS-150, annual UCR. The failure mode is never ignorance. It is a date passing while you were driving. Whether you use a wall calendar, a spreadsheet, or a service like ours, the system matters more than the tool.
