Every driver who hauls fuel for you under a CDL needs a driver qualification file, and the Federal Motor Carrier Safety Administration is specific about what goes in it. The file has to hold the driver's employment application, a motor vehicle record from each state where they were licensed, a road test certificate (which your tank drivers actually need, because a CDL cannot stand in for the road test on a tank vehicle), their prior three years of employment history, a current medical examiner's certificate, and a record of your annual review of their driving record. You keep that file for the entire time the driver works for you, and for three years after they leave. Come up short during a compliance review and you get written up for the paperwork, even when the driver is perfectly safe.
The short version: what belongs in the file
The contents are set out in 49 CFR 391.51. This is the checklist an auditor works from, so it is the one you should build your file around. Nothing here is optional for a driver operating a commercial motor vehicle in interstate commerce.
- Employment application. The driver's application for employment under 391.21, filled out completely, including the required list of prior employers and any accidents.
- MVR at hire. A motor vehicle record obtained from every state where the driver held a license or permit during the past three years (391.23). You request it; the driver does not supply it.
- Safety performance history. Your written inquiries to the driver's DOT-regulated employers for the prior three years, and their responses (391.23). Keep proof you asked, even when an old employer never replies.
- Road test certificate. A copy of the road test certificate under 391.31. The CDL substitution under 391.33 is not available for tank vehicles, so your fuel drivers need an actual road test and certificate on file, not a copied CDL.
- Medical examiner's certificate. A current med card under 391.43, plus your verification that the examiner is listed on the National Registry.
- Annual MVR and review note. A fresh MVR pulled at least every 12 months (391.25), and a dated note showing you reviewed it and judged the driver still qualified.
The road test and why the CDL shortcut does not apply to tank drivers
Under 391.33 some carriers accept a copy of the driver's valid CDL in place of the road test. For fuel haulers, that shortcut is off the table. 391.33(a)(1) explicitly excludes tank vehicles and double or triple trailer combinations from the CDL substitution. A tank vehicle under 383.5 is one carrying a tank of 1,000 gallons or more, which is exactly what your delivery drivers run, so the CDL cannot stand in for the road test on those trucks.
That makes the road test a requirement for your tank drivers, not a preference. You have to run an actual road test under 391.31 and file the signed certificate, or use a road test certificate the driver already holds for the tank vehicle type. What you cannot do is drop a copied CDL in the file and call the road test satisfied. For a fuel driver that leaves a gap the regulation does not allow, and an auditor will write it up. Road-testing a driver on backing a loaded transport into a tight retail lot is good operating practice on its own, but the compliance point is firmer than that: on a tank vehicle the road test and certificate are mandatory.
Medical certificates and the CDLIS wrinkle
The medical examiner's certificate proves the driver is physically cleared to drive. It has to come from a provider on FMCSA's National Registry of Certified Medical Examiners, and you are expected to verify that. Most med cards run for up to 24 months, and some are shorter when the examiner notes a condition to watch, so the expiration date is something you track, not something you file and forget.
For CDL holders there is a twist worth knowing. States now post a driver's medical certification status to the CDLIS motor vehicle record, so the MVR itself can serve as proof of medical certification. You still confirm the status and keep your records straight, but the CDLIS MVR is doing part of the job the paper card used to do alone. If your drivers are non-CDL operating smaller commercial vehicles, the paper certificate is still your primary proof.
The annual MVR review most jobbers forget
The hire-day MVR is the part everyone remembers. The annual one is the part that trips people up. At least once every 12 months you have to pull a new MVR for each driver, look at it, and write a dated note stating whether the driver still meets your standards and the FMCSA requirements. That review note is a separate document from the MVR itself, and auditors check for both.
For a jobber running six or eight drivers this is easy to let slide, because nothing breaks when you miss it. The gap only shows up when someone asks for the file. This is the kind of recurring date that fuel back-office systems are built to track alongside your dispatch and delivery records, and the same software you use to run deliveries can flag a med card or an annual MVR before it lapses. If you are running this on a wall calendar, at least put every driver's med expiration and annual review date on one page you look at monthly.
How long you keep it: employment plus three years
Here is the retention rule in one line: keep the driver qualification file for as long as the driver works for you, and for three years after they leave. That covers the whole file. So a driver who was with you for nine years and quit last spring still has a file you are required to hold until roughly three years from their last day.
A few items inside the file also have their own three-year clock while the driver is active. The annual MVR and the annual review note can be removed three years after they were made, since a newer one has replaced them each year. The practical move is to keep a rolling three years of MVRs and review notes and not purge the current file down to the bone. Storage is cheap; a missing record during an audit is not.
What does not go in the DQ file
Drug and alcohol testing records are not part of the driver qualification file. Pre-employment test results, random testing records, and your clearinghouse queries live in a separate, access-controlled file under Part 382 and Part 40. Auditors look at both, but they are kept apart, and mixing them is a common filing mistake. Hours-of-service logs and vehicle inspection records are also their own thing, not DQ material.
If you are new to running your own trucks and still sorting out which side of the business each rule sits on, it helps to have the operating picture first. Our guide on how to become a fuel jobber lays out where fleet compliance fits against supply, credit, and the rest, and what a fuel jobber actually does frames why a small marketer ends up wearing the safety-manager hat at all.
Build the file the way an auditor reads it
The cleanest DQ files are boring and in order: one folder per driver, the 391.51 items in the same sequence every time, dates visible, nothing loose. During a new-entrant safety audit or a compliance review, the officer is checking whether the required document exists and is current, not judging your filing taste. A file that mirrors the regulation lets them tick each box and move on.
The write-ups that sting are almost never about unsafe driving. They are about a road test certificate nobody signed, a copied CDL sitting where a tank driver's road test should be, an annual MVR that is 14 months old, or a med card that lapsed in the file while the driver kept a valid one in his wallet. Every one of those is a paperwork gap you can close before anyone asks.
Questions people ask
Do intrastate fuel drivers who never cross a state line need a DQ file?
Usually yes, but the rule comes from your state rather than FMCSA directly. Most states have adopted the federal Part 391 requirements, sometimes with their own tweaks for intrastate-only drivers, medical waivers, or younger drivers. Check your state's motor carrier or DOT rules, because a purely intrastate operation still almost always has to keep qualification records.
What about a driver in a smaller truck who does not hold a CDL?
If the vehicle meets the definition of a commercial motor vehicle, the driver still needs a qualification file even without a CDL. The medical certificate stays a paper card in the file since there is no CDLIS record doing that job, and you cannot use the CDL-in-lieu-of-road-test shortcut, so an actual road test and certificate are required.
Who is allowed to give the road test, and does a prior employer's certificate count?
Whoever conducts the road test has to be competent to observe and rate the driver, which can be you, a supervisor, or a qualified person you designate; the driver cannot test themselves. If a new hire already earned a signed certificate on the same class of tank vehicle, 391.31(e) lets you accept and file that certificate instead of running the test again. Just confirm the certificate covers the type of equipment they will actually operate for you, and keep the original or a legible copy in the file.
Who keeps the DQ file for a leased owner-operator?
The motor carrier whose authority the truck runs under is responsible for the qualification file, even when the driver owns the equipment. If you lease on an owner-operator to haul under your DOT number, you maintain the file and pull the annual MVR, the same as you would for a company driver.
How often does FMCSA actually look at these files?
Most operators first see a full review during a new-entrant safety audit in their opening months, then again in any compliance review triggered by crash history, a complaint, or poor CSA scores. Files can also be requested after a roadside inspection turns up a problem, so treat them as always inspection-ready rather than something you scramble to assemble.
