Driver Qualification File Checklist (49 CFR 391.51)

Written by the Logity Dispatch team for carriers running one truck or a small fleet. Every rule below was checked on 5 October 2026 against 49 CFR parts 382, 385, 390 and 391 as served by the eCFR API at title 49’s 1 October 2026 issue date. This is a checklist of what the federal rules require of interstate carriers. It is not legal advice, and it does not cover state rules for intrastate operations.

What is a driver qualification file?

A driver qualification file, usually shortened to DQ file, is the set of records that shows a motor carrier checked a driver before letting them drive and keeps checking them while they drive. The rule that creates it is one sentence long. Section 391.51(a) says: “Each motor carrier shall maintain a driver qualification file for each driver it employs.” The same paragraph adds that the file “may be combined with his/her personnel file”, so it does not need its own cabinet, but every item has to be there and has to be findable.

The file applies to drivers of commercial motor vehicles. In interstate commerce, 49 CFR 390.5 defines a commercial motor vehicle to include one with a gross vehicle weight rating or gross combination weight rating, or gross vehicle weight or gross combination weight, of 10,001 pounds or more, whichever is greater. That threshold is far below the weight at which a CDL becomes necessary, which is why a box truck carrier with non-CDL drivers still needs a DQ file for each of them.

“Employs” is wider than a W-2. The definition of employee in 390.5 covers a driver of a commercial motor vehicle “including an independent contractor while in the course of operating a commercial motor vehicle”. A leased-on owner-operator hauling under your authority is your driver for this purpose, and you keep the file.

Do you need a DQ file if you are the only driver?

Yes. This is the question owner-operators with their own authority ask most, and Part 391 answers it directly. Section 391.1(b): “An individual who meets the definition of both a motor carrier and a driver employed by that motor carrier must comply with both the rules in this part that apply to motor carriers and the rules in this part that apply to drivers.”

In practice that means you fill in an employment application as the driver and keep it as the carrier, you pull your own motor vehicle record, and you review it once a year and write the note. One item cannot be done alone. The road test rule in 391.31(b) says “a driver who is a motor carrier must be given the test by a person other than himself/herself.” If you hold a CDL, the equivalent in 391.33 usually covers this; more on that in the checklist below.

What goes in a driver qualification file?

Section 391.51(b) lists what the file “must include”. Below is that list turned into a checklist, with the rule behind each item, the deadline, and the retention period. Print it, or copy the rows into whatever system you keep files in.

Document	Rule	When it must be in place	How long it stays
Employment application, completed and signed by the driver	391.21; 391.51(b)(1)	Before the driver drives (391.21(a))	Employment plus 3 years
Motor vehicle record from each state that licensed the driver in the past 3 years, covering 3 years	391.23(a)(1), (b); 391.51(b)(2)	Within 30 days of the date employment begins	Employment plus 3 years
Certificate of road test, or a copy of the CDL or road test certificate accepted as its equivalent	391.31(e), (g); 391.33; 391.51(b)(3)	Before the driver drives (391.31(a))	Employment plus 3 years
Annual motor vehicle record from each state that licensed the driver, covering at least the past 12 months	391.25(a), (c)(1); 391.51(b)(4)	At least once every 12 months	May be removed 3 years after the date of execution
Annual review note, with the reviewer’s name and the date	391.25(b), (c)(2); 391.51(b)(5)	At least once every 12 months	May be removed 3 years after the date of execution
Medical certification: the medical examiner’s certificate or a legible copy; for CDL holders, the CDLIS motor vehicle record from the current licensing state	391.23(m); 391.51(b)(6)	Before the driver drives, then on every recertification (at least every 24 months under 391.45(b))	May be removed 3 years after the date of execution
Medical variance, Skill Performance Evaluation Certificate or federal medical exemption, if the driver has one	391.51(b)(6)(iii), (b)(7)	With the medical certification it supports	May be removed 3 years after the date of execution
Non-CDL drivers: note that the medical examiner was listed on the National Registry of Certified Medical Examiners	391.23(m)(1); 391.51(b)(8)(i)	Before the driver drives	May be removed 3 years after the date of execution
CDL and CLP holders: documented check of the self-certified type of operation and, for interstate drivers, a valid medical certificate, both from the CDLIS record	391.23(m)(2), (m)(3)	Before the driver drives	Kept with the CDLIS record

A few rows need more than a line.

The application. Section 391.21(b) says it is made “on a form furnished by the motor carrier” and lists what it must contain: the carrier’s name and address; the driver’s name, address, date of birth and social security number; addresses for the past 3 years; every unexpired commercial motor vehicle operator’s license or permit; driving experience by type of equipment; accidents and moving violations in the past 3 years; any license denial, revocation or suspension, or a statement that there was none; employers for the past 3 years, with dates and the reason for leaving; and, for drivers applying to operate a vehicle that requires a CDL, a further 7 years of employers for whom they drove a commercial motor vehicle. It ends with the certification the rule writes out word for word: “This certifies that this application was completed by me, and that all entries on it and information in it are true and complete to the best of my knowledge.” Before the applicant fills it in, 391.21(d) requires you to tell them that previous employers will be contacted and to give them written notice of their rights to review and rebut what those employers send.

The motor vehicle record. The pre-hire inquiry goes “to each driver’s licensing authority where the driver held or holds a motor vehicle operator’s license or permit during the preceding 3 years” (391.23(a)(1)). A driver who moved from Texas to Ohio last year needs two records, not one. If a state does not answer, 391.23(b) requires you to document a good faith effort to get the record. Our guide to what a clean driving record is and what employers see on an MVR covers the record itself.

The road test. The person who gives it rates the driver on a road test form and signs it, and the file keeps “the original of the signed road test form” and the original or a copy of the certificate (391.31(g)). Instead of a road test, 391.33(a) lets a carrier accept a valid CDL, not counting double/triple trailer or tank vehicle endorsements, issued after a road test in the type of vehicle the driver will be assigned, or a copy of a road test certificate issued within the preceding 3 years. If you accept either, keep “a legible copy of the license or certificate” in the file (391.33(b)). For a non-CDL box truck driver there is no license to accept, so the road test is real.

The medical certification. This row changed in 2025, and many printable checklists still show the old version. Under 391.43(g)(2)(ii), on or after June 23, 2025 the medical examiner completes and hands over the paper certificate when the driver “will not be operating a commercial motor vehicle that requires a commercial driver’s license or a commercial learner’s permit”. For CDL holders the proof is the CDLIS motor vehicle record from the current licensing state, which carries the medical certification status, and 391.51(b)(6)(ii) says the carrier “must meet this requirement by obtaining the CDLIS motor vehicle record”. The 15-day grace for a copy of a new certificate, and the separate National Registry note for CDL drivers, both ran “through June 22, 2025” and are gone. Our article on the DOT physical and CDL medical card covers the exam and renewal side.

What does not go in the DQ file?

Three sets of records sit next to the DQ file and are often stuffed into it. The rules keep them apart, and an auditor will look for them separately.

The driver investigation history file. The replies from previous employers about the driver’s safety performance history go into a different file under 391.53. It holds the driver’s written authorization to ask about alcohol and drug history, and every previous employer’s response or your documented good faith attempts to get one, with “the previous employer’s name and address, the date the previous employer was contacted, and the information received about the driver”. This file “must be maintained in a secure location with controlled access”, access is limited to the people making the hiring decision, and 391.53(a)(2) is blunt: “This data must only be used for the hiring decision.” The replies have to be in place within 30 days of the date employment begins (391.23(c)(1)), and for a hired driver they are kept for the employment plus three years (391.53(c)). For a driver with no DOT-regulated employment in the past three years, the file holds documentation that no investigation was possible (391.23(c)(4)).

Drug and alcohol testing records. Test results, refusals, SAP evaluations and the rest of the testing program records are kept under Part 382, and 382.401(a) says “The records shall be maintained in a secure location with controlled access.” Section 391.51(b) does not list a drug test result as a DQ file item. The coordination side of testing, meaning who books the collection and how the load gets covered, is in our piece on drug and alcohol testing and dispatch coordination.

Clearinghouse queries. Section 382.701(a) says employers “must not employ a driver subject to controlled substances and alcohol testing under this part to perform a safety-sensitive function without first conducting a pre-employment query of the Clearinghouse”. That pre-employment query has to be a full query, which needs the driver’s specific consent, and since January 6, 2023 the Clearinghouse is also how you check previous FMCSA-regulated employers for drug and alcohol violations (391.23(e)(4)). For the query records themselves, 382.701(e) says employers “must retain for 3 years a record of each query and all information received in response to each query”, and adds: “As of January 6, 2023, an employer who maintains a valid registration fulfills this requirement.” Consent for queries is kept for 3 years from the date of the last query (382.703(a)). Many carriers print the query result and drop it into the driver’s folder. That is fine for convenience, but 391.51(b) does not list it, and the record that counts is the one in your Clearinghouse account.

What has to happen before a new driver’s first load?

Some items are due before the driver moves a truck, others within 30 days of the start date. Mixing up the two lists is the usual way a carrier ends up with a driver running loads on an incomplete file. This is the order that keeps every gate closed until it should open.

1. Give the notices and take the application. Tell the applicant that previous employers will be contacted and give the written notice of review and rebuttal rights (391.21(d), 391.23(i)). Then take the signed application (391.21(a)).
2. Get consent and run the Clearinghouse full query. If the driver refuses consent for the query, 391.23(f)(2) says you “must not permit the driver to operate a commercial motor vehicle.”
3. Get a verified negative pre-employment drug test. Under 382.301(a), no employer may let the driver perform safety-sensitive functions “unless the employer has received a controlled substances test result from the MRO or C/TPA indicating a verified negative test result for that driver.” The narrow exception in 382.301(b) has three conditions, all of which you have to be able to show.
4. Verify the medical certification. Get the certificate, or for a CDL holder the CDLIS record, check the examiner against the National Registry where the rule requires it, and put the records in the file “before allowing the driver to operate a CMV” (391.23(m)(1)).
5. Road test, or accept the equivalent. Under 391.31(a) a person shall not drive a commercial motor vehicle until they have completed the road test and been issued the certificate, unless 391.33 applies.
6. Within 30 days: the motor vehicle records. One from every state that licensed the driver in the past three years, placed in the DQ file (391.23(b)).
7. Within 30 days: previous employer replies. Safety performance history from each DOT-regulated employer in the past three years, or your documented good faith efforts, placed in the investigation history file (391.23(c)(1)).

Steps 1 to 5 are gates: the driver does not drive until each is done. Steps 6 and 7 have a 30-day clock, but run them on day one. A motor vehicle record that comes back with a disqualifying violation after two weeks of loads is a much worse problem than one that comes back before the first. If you hand drivers’ paperwork to a dispatcher as well, our list of onboarding documents your dispatcher actually needs explains which pieces belong with dispatch and which do not.

What do you have to update every year?

A DQ file is not finished at hire. Three items run on a 12-month clock and one on a medical clock. Put each date in a calendar the day the driver starts.

Recurring item	Rule	Frequency	What goes in the file
Motor vehicle record inquiry	391.25(a)	At least once every 12 months	The record from each state that licensed the driver, covering at least the preceding 12 months
Review of the driving record	391.25(b), (c)(2)	At least once every 12 months	A note with the name of the reviewer and the date of the review
Clearinghouse query	382.701(b)	At least once per year	Nothing required in the DQ file; your registration holds the query record
Medical certification	391.45	At least every 24 months; at least every 12 months for drivers certified under 391.46 (insulin-treated diabetes) or 391.44 (vision)	The new certificate or, for CDL holders, a new CDLIS motor vehicle record

Pulling the record is not the same as reviewing it. Section 391.25(b) requires you to review the record “to determine whether that driver meets minimum requirements for safe driving or is disqualified to drive a commercial motor vehicle pursuant to § 391.15”. In that review you must consider the driver’s accident record and violations, and 391.25(b)(2) says you “must give great weight to violations, such as speeding, reckless driving, and operating while under the influence of alcohol or drugs”. The proof that you did it is the note, and 391.25(c)(2) spells out what it contains: a note “including the name of the person who performed the review of the driving record required by paragraph (b) of this section and the date of such review”. A record with no note is half the job.

Older checklists also list an annual list of violations signed by the driver. That came from 391.27, and in the current text of Part 391 that section reads “[Reserved]”. The annual record pull and review above is what remains.

For the annual Clearinghouse query, a limited query is enough if the driver has consented to it, and 382.701(b)(2) lets that consent be effective for more than one year. If the limited query shows that information exists, you must run a full query within 24 hours, and until you do, the driver does not perform safety-sensitive functions (382.701(b)(3)).

How long do you keep a driver qualification file?

The default in 391.51(c) is that the file “shall be retained for as long as a driver is employed by that motor carrier and for three years thereafter.” A driver who worked for you for six years and left on 1 March 2026 has a file you keep until 1 March 2029.

Section 391.51(d) lets you thin the file while the driver is still with you. Five kinds of record “may be removed from a driver’s qualification file three years after the date of execution”. The pre-hire items are not on that list, so they stay for the full period.

Record	Retention	Rule
Employment application, pre-hire motor vehicle records, road test certificate or equivalent	Employment plus 3 years	391.51(c)
Annual motor vehicle records	May be removed 3 years after the date of execution	391.51(d)(1)
Annual review notes	May be removed 3 years after the date of execution	391.51(d)(2)
Medical examiner’s certificates, or CDLIS motor vehicle records used for medical certification	May be removed 3 years after the date of execution	391.51(d)(3)
Medical variances, SPE certificates, medical exemption letters	May be removed 3 years after the date of execution	391.51(d)(4)
National Registry verification notes	May be removed 3 years after the date of execution	391.51(d)(5)
Safety performance history from previous employers (investigation history file, hired drivers)	Employment plus 3 years	391.53(c)
Clearinghouse query records	3 years	382.701(e)
Clearinghouse query consent	3 years from the date of the last query	382.703(a)

“May be removed” is permission, not an instruction. Nothing in 391.51 requires you to take anything out early, and keeping records longer does not break the rule. The longer table of retention periods across a small fleet, including hours of service and maintenance records, is in our truck fleet management guide.

Can a DQ file be kept on paper copies or digitally?

Yes to both, with conditions. Section 390.31 says that, except as otherwise provided, “copies that are legible and accurately reflect the information required to be contained in the record or document may be maintained in lieu of originals.” Section 390.32(b) lets anyone required to keep these documents “use electronic methods to satisfy those requirements”, and 390.32(c) allows electronic signatures.

Note the “except as otherwise provided”. The road test rule asks for “the original of the signed road test form” (391.31(g)(1)), so if you go digital, make sure the original is the electronic one, signed electronically, or keep the paper. And 390.32(d) says electronic records do not satisfy the rule if they “cannot be accurately reproduced within required timeframes for reference by any party entitled to access.” A scanned file that only one person can open, on a laptop that is on the road, fails that test in an audit.

What happens in an audit if a DQ file is incomplete?

FMCSA scores audits against a list of “acute” and “critical” regulations in Appendix B to Part 385. Critical regulations are those where “noncompliance relates to management and/or operational controls.” Several DQ file items are on that list by name:

Regulation	Violation as listed in Appendix B to Part 385	Class
391.51(a)	Failing to maintain driver qualification file on each driver employed	Critical
391.51(b)(2)	Failing to maintain inquiries into driver’s driving record in driver’s qualification file	Critical
391.51(b)(6)	Failing to maintain medical examiner’s certificate in driver’s qualification file	Critical
391.45(a)	Using a driver not medically examined and certified	Critical
391.45(b)	Using a driver not medically examined and certified during the preceding 24 months	Critical
391.11(b)(4)	Using a physically unqualified driver	Acute
391.15(a)	Using a disqualified driver	Acute

For a new carrier the stakes are concrete. In the new entrant safety audit under Appendix A to Part 385, each instance of noncompliance with a critical regulation scores 1 point and each acute one scores 1.5. Parts 382, 383 and 391 together make up Factor 2, the driver factor, and “if the combined violations of acute and/or critical regulations for each factor is equal to three or more points, the carrier is determined not to have basic safety management controls for that individual factor.” On top of the points, 385.321(b) lists 16 violations that fail a new entrant audit on their own, and two of them come straight from Part 391: “Knowingly using a disqualified driver” (391.15(a)) and “Knowingly using a physically unqualified driver” (391.11(b)(4)). Each is marked “Single occurrence.”

The arithmetic is unkind to small carriers. A one-truck operation with no DQ file on itself and an expired medical certificate in the file it does have can reach three points in the driver factor from the DQ file alone. What triggers audits and how carriers come through them is in our guide to DOT audits in 2026, and the new entrant version is explained in what a safety audit is in trucking.

Which gaps should you check for before an auditor does?

Open each driver’s file and run these checks. Each one maps to a rule above, and each is a place where a file can look complete and still fail.

• Motor vehicle records from every state. Compare the license history on the application with the records in the file. One record for a driver who held licenses in two states in the past three years is a gap.
• Dates against the start date. The pre-hire record and the previous employer replies are each due within 30 days of the date employment began. Check the dates on the documents, not the date you filed them.
• A review note for every annual record. Each annual record needs a note with a reviewer’s name and a date beside it.
• A current medical certification. Check the expiration date on the certificate or the CDLIS record today, not the day you filed it. For CDL drivers hired or recertified since June 23, 2025, look for the CDLIS record, not just a paper card.
• The road test certificate is signed. Or, if you accepted a CDL as the equivalent, a legible copy of that license is in the file.
• The application is complete. Three years of addresses and employers, for CDL drivers a further seven years of employers they drove a commercial motor vehicle for, and the signed certification at the end.
• Your own file, if you drive. Owner-operators with their own authority skip this one more than any other.
• Former drivers. Files for drivers who left in the past three years are still due. Make sure they were not thrown out with the termination paperwork.

Where does a compliance service fit into this?

None of the items above is hard on its own. What breaks files is the calendar: a 30-day clock on every new hire, a 12-month clock on every driver, a medical clock that differs from driver to driver, and a three-year tail on everyone who leaves. With two or three drivers that is already a dozen dates a year, and nobody is paid to watch them.

That calendar is what our safety and DOT compliance service takes over. The service covers “Creation and management of driver qualification files (driving/employment history, certificates, annual updates)”, and we track, update and audit the files and send reminders for renewals and deadlines. The next step is simple: tell us how many drivers you run and when each one started, including yourself if you drive, and we set up the files and the dates. You can reach us through the contact page.

Frequently asked questions

Does an owner-operator need a driver qualification file?

Yes, if they drive under their own authority. Under 49 CFR 391.1(b), a person who is both the motor carrier and its driver must follow both sets of Part 391 rules. A leased-on owner-operator is covered by the carrier they haul for, which keeps the file.

How long do you keep a driver qualification file?

For as long as the driver is employed and three years after, under 49 CFR 391.51(c). Annual motor vehicle records, review notes, medical certificates, variances and National Registry notes may be removed three years after the date they were executed, under 391.51(d).

Does a drug test result go in the DQ file?

No. 49 CFR 391.51(b) does not list it. Drug and alcohol testing records are kept under 49 CFR 382.401 in a secure location with controlled access, and previous employer drug and alcohol history goes in the separate driver investigation history file under 391.53.

How often does a DQ file need to be updated?

At least every 12 months: a new motor vehicle record from each licensing state and a review note with the reviewer’s name and date, under 49 CFR 391.25. The medical certification is renewed at least every 24 months, or every 12 months for some drivers under 391.45.

Can a driver qualification file be digital?

Yes. 49 CFR 390.32 allows electronic records and electronic signatures, as long as the records accurately reflect the required information and can be reproduced within the required timeframes for anyone entitled to access them. Section 390.31 allows legible copies in place of originals unless a rule says otherwise.
