Here’s a driver qualification file problem that doesn’t look like a problem.
You hire a driver. You collect the application, run the driving record, file everything the checklist says to file. The DQF is neat, complete, and exactly what you’d hand an auditor with confidence.
And it’s missing a federally required record — one you never knew to request, because the only person who could have told you about it had no reason to.
What the regulation actually requires
Most carriers think of the driving record as a single item on the DQF checklist. It isn’t. Read the two rules together:
49 CFR 391.23(a)(1) requires an inquiry, within 30 days of the date the driver’s employment begins, to each driver’s licensing authority where the driver held or holds a license or permit during the preceding three years, to obtain that driver’s motor vehicle record.
49 CFR 391.51 then requires that the driver qualification file contain a copy of the motor vehicle record received from each licensing authority under 391.23(a)(1).
Note the word doing the work: each. Not “the driver’s current state.” Not “one MVR.” A record from every authority that licensed them in the last three years — and those records have to be in the file within 30 days of the start date.
For a driver who has only ever been licensed in one state, that’s one MVR and you’re done. For a driver who moved, that’s two or three — and the regulation does not care whether you knew about them.
The gap: you can only request what you know about
Here’s the mechanism that creates the problem.
To request a driving record from a state, you have to know the driver was licensed there. Where does that knowledge come from? The driver’s application. Federal rules require applicants to list the commercial licenses they’ve been issued — but that is a self-declaration, collected from the one person with a reason to leave something off.
So the chain runs:
- The driver lists the states they choose to list.
- You request driving records from exactly those states.
- Those records go in the DQF.
- The file is now “complete” — measured against what the driver told you.
If the driver held a CDL in a state they didn’t mention, or held one under a former name, step 2 never happens for that state. No record is requested, none arrives, and nothing in the file indicates one is missing. The gap is invisible from inside the file.
That’s the part worth sitting with: a DQF audit checks whether the documents you collected are present and current. It does not tell you whether a document you never knew to collect is absent.
Who this actually happens to
This isn’t an exotic edge case. The drivers it affects are ordinary:
- The driver who moved. Licensed in one state three years ago, licensed in yours now. If the application only lists the current license, the prior state’s record never gets requested — and that’s the state where the history lives.
- The driver who changed names. A marriage or divorce in the last few years means prior licensing records may sit under a different name entirely. A search on their current name finds nothing.
- The driver who shouldn’t have two licenses. Under 49 CFR 383.21 a commercial driver may not hold more than one license. Drivers who do have one are not going to volunteer the second one on your application.
The first two are usually innocent — a driver filling out a form quickly, not thinking a five-year-old license matters. The third is the one that should worry you. And your file looks identical in all three cases.
Why this lands on the carrier, not the driver
It would be reasonable to think an incomplete application is the driver’s problem. Federal rules don’t see it that way.
Under 49 CFR 383.37, no employer may allow a driver to operate a commercial motor vehicle if the employer “knows or should reasonably know” the driver holds more than one CLP or CDL.
“Should reasonably know” is the phrase to read twice. It is not a standard about what you actually knew — it’s a standard about what a reasonable carrier in your position would have found out. If a driver was carrying a second license, and a routine, inexpensive, widely available check would have surfaced it, “he didn’t tell us” is a difficult position to hold after an incident or in front of an auditor.
The record-keeping duty works the same way. 391.51 requires the records to be in the file. It does not offer an exception for records you didn’t know existed.
How to close the gap
You close it by checking whether other licenses exist before you decide which driving records to order — instead of taking the application’s word for it.
That’s what a CDLIS search does. CDLIS — the Commercial Driver’s License Information System — is the nationwide system that links every state’s licensing agency, created to enforce the principle of one driver, one license, one record. An employer CDLIS search returns:
- The driver’s current CDL number and issuing state
- Prior commercial licenses and the states that issued them
- Aliases and former names attached to those records
It does not return violations or driving history — that’s not what it’s for, and any provider telling you otherwise is describing a different product. What it returns is the answer to “which licensing authorities belong in this driver’s file?” — which is precisely the question 391.23(a)(1) assumes you can already answer.
Run it first, then order driving records from every state it surfaces. Now the MVRs in your DQF are the complete set the regulation actually requires, rather than the subset the driver disclosed.
Is a CDLIS search required?
No. No federal regulation mandates a standalone CDLIS search or sets a frequency for one, and you’ll see vendors claim otherwise — their citations don’t support it.
What the regulations require is the outcome: a driving record from each licensing authority in the file, and no driver operating with two licenses. A CDLIS search is simply the practical way to achieve both instead of hoping the application was complete.
We recommend it on every driver at hire, run alongside the driving record. At $10 it’s the least expensive item in the qualification file, and it’s the one that tells you whether everything else in there is actually complete.
Frequently Asked Questions
How many MVRs does a driver qualification file need?
One from each licensing authority where the driver held or holds a license during the preceding three years, per 49 CFR 391.23(a)(1), with copies retained in the file under 49 CFR 391.51. A driver licensed in only one state needs one. A driver who moved may need two or three.
What if I didn’t know a driver was licensed in another state?
The regulation doesn’t provide an exception for records you didn’t know to request — the file is still short a required document. That’s why carriers verify licensing history independently of the application rather than relying on it, typically with a CDLIS search before ordering driving records.
Does a CDLIS search show driving violations?
No. A CDLIS search returns identification data — the driver’s current CDL, prior commercial licenses and issuing states, and aliases or former names. Violations live on the state driving record and are obtained separately. CDLIS tells you which states to request records from; the MVR tells you what’s on the record.
How long do driving records have to stay in the DQF?
The driver qualification file must be retained for as long as the driver is employed and for three years afterward, under 49 CFR 391.51.
Is a CDLIS search required by FMCSA?
No. No regulation mandates a standalone CDLIS search. The requirements it helps you meet are real — 391.23(a)(1) and 391.51 for the records, and 383.37 for the one-license rule — but the search itself is best practice, not a mandate.
How much does a CDLIS search cost?
Vertical Identity members pay $10 per CDLIS search, ordered in the member portal, with results filed directly into the driver’s qualification file. Published market pricing elsewhere generally runs from about $6 to $15.
Find the record before the auditor does
A DQF that’s missing a required MVR looks exactly like a DQF that isn’t. That’s the whole problem — and it’s why the check that reveals which states belong in the file is worth running before you need it.
Vertical Identity members order CDLIS searches alongside driving records, PSP reports, background checks and Clearinghouse queries in one portal, with results filing straight into the driver’s qualification file.
