Hiring a Truck Driver: The Qualification File, Before and After Day One

A driver may not drive a commercial motor vehicle for a carrier until he or she has completed and furnished the carrier's application for employment (391.21(a)). The form is the carrier's; the applicant completes and signs it, and 391.21(b) sets what it must ask:

• name, address, date of birth and Social Security number, and every address in the 3 years before the application (391.21(b)(2), 391.21(b)(3));
• each unexpired commercial motor vehicle operator's license or permit, with the issuing authority, number and expiry (391.21(b)(5));
• driving experience and the types of equipment driven (391.21(b)(6));
• accidents and traffic convictions other than parking in the 3 preceding years, and any license denial, suspension or revocation (391.21(b)(7) to 391.21(b)(9));
• employers in the 3 preceding years, with dates, reasons for leaving, and whether the job was under the FMCSRs and a DOT-tested safety-sensitive position (391.21(b)(10));
• for a driver applying to drive a vehicle that needs a CDL, the commercial driving employers in the 7 years before those 3, for 10 in all (391.21(b)(11));
• the signed certification that the entries are true and complete (391.21(b)(12)).

Before the application is submitted, the carrier tells the applicant that previous employers will be contacted for the safety performance history investigation, and gives written notice of the driver's rights to review, correct and rebut what they send (391.21(d), 391.23(i)(1)). The investigations work from this application, so a gap in the employment list is a gap in the investigation. The field-by-field detail is in the driver employment application guide.

The second inquiry is an investigation of the driver's safety performance history with DOT-regulated employers during the preceding 3 years (391.23(a)(2)). For each employer that had the driver operating a commercial motor vehicle in that time, it covers at least general identification and employment verification and the accidents described in 390.15(b)(1) for the 3 years before the application, and the request tells the previous employer where to send the answer (391.23(d)).

The replies, or documentation of good-faith efforts to get them, go in the driver investigation history file within 30 days of the date employment begins (391.23(c)(1)). For every previous employer the carrier keeps a written record: the employer's name and address, the date of contact or the attempts made, and what came back (391.23(c)(2)). The rule names no number of attempts; it asks for that record. Carriers should report an employer that will not respond to FMCSA through the 386.12 complaint procedure and keep a copy as part of the good-faith record (391.23(c)(3)). For a driver with no DOT-regulated employment in the 3 years, the file documents that no investigation was possible (391.23(c)(4)).

The investigation also asks each previous employer that tested the driver under 49 CFR Part 40 about drug and alcohol violations in the 3 years and any return-to-duty process (391.23(e)). Since January 6, 2023, carriers subject to 382.701(a) get that from the Drug and Alcohol Clearinghouse for FMCSA-regulated employers (391.23(e)(4)); employers in other DOT modes are asked directly (391.23(e)(4)(ii)), with the driver's written consent, and a driver who refuses that consent may not drive for the carrier (391.23(f)(1)).

The replies belong in the investigation history file, kept in a secure place with controlled access and used only for the hiring decision, not in the driver qualification file (391.53(a)). How to write the request and what previous employers owe in return are in the safety performance history guide.

No driver drives a commercial motor vehicle for the carrier until he or she has passed a road test and been issued a certificate (391.31(a)). The carrier, or a person it designates who is competent to judge the driver on the equipment the carrier will assign, gives the test, and a driver who is the motor carrier is tested by someone else (391.31(b)). It covers at least the pretrip inspection, coupling and uncoupling where combinations are used, placing the vehicle in operation, the controls and emergency equipment, driving in traffic and passing, turning, braking and slowing without the brakes, and backing and parking (391.31(c)). The examiner rates each item on a road test form and signs it (391.31(d)) and completes the certificate (391.31(e)); the qualification file keeps the original signed form and the original or a copy of the certificate (391.31(g)).

In place of the test the carrier may accept a valid CDL earned with a road test in the type of vehicle the carrier will assign, not counting double/triple trailer or tank vehicle endorsements (391.33(a)(1)), or a copy of a road test certificate issued within the preceding 3 years (391.33(a)(2)). A legible copy of what was accepted goes in the file (391.33(b)), and the carrier may still require its own test (391.33(c)). A driver with no CDL has only the certificate route, or the test. The full rules are in the road test guide.

A driver must be medically certified as physically qualified before operating a commercial motor vehicle (391.41(a)(1)(i)). What the carrier files depends on the license:

• A driver who needs no CDL: the carrier obtains the original or a copy of the medical examiner's certificate, verifies that the examiner was on the National Registry on the date of issue, and places both in the file before the driver operates (391.23(m)(1)).
• A CDL driver: the carrier uses the CDLIS record from the current licensing State to verify and document the self-certified type of operation and, for an interstate driver, a valid certificate and any required variance, before the driver operates (391.23(m)(2)). That record is the file document (391.51(b)(6)(ii)).

The paper medical card exemption that let carriers rely on a copy for 60 days ended October 11, 2026 for drivers licensed outside Alaska. What that changed is on the paper medical card waiver page.

Part 382 applies to drivers subject to the CDL requirements of Part 383, and to their employers (382.103(a)). For those drivers the carrier may not let a new driver perform any safety-sensitive function until it has received a verified negative controlled substances result from the medical review officer or the consortium or third-party administrator (382.301(a)). Safety-sensitive functions begin with time waiting to be dispatched and include inspecting equipment and loading, not only driving (382.107).

The test may be skipped only when all three hold: the driver took part in a Part 382 testing program within the previous 30 days; while in it, was tested within the past 6 months or was in the random program for the previous 12 months; and no prior employer the carrier knows of has a record of a violation in the previous 6 months (382.301(b)). A carrier that uses the exception obtains and keeps the program's details, including the date of the driver's last test (382.301(c)). Pre-employment alcohol testing is optional, and a carrier that does it tests every new safety-sensitive employee the same way, after a contingent offer (382.301(d)).

A carrier whose only driver is its owner meets both the employer and the driver requirements, and keeps the owner in a random testing pool of two or more covered employees (382.103(b)).

Before a driver subject to Part 382 performs a safety-sensitive function, the carrier runs a pre-employment query of the Drug and Alcohol Clearinghouse, and it must be a full query (382.701(a)(1), 382.701(a)(2)). The carrier needs the driver's written or electronic consent before it queries, and keeps that consent for 3 years from the last query (382.703(a)); the full query also needs the driver's specific consent, given electronically in the Clearinghouse (382.703(b), 382.703(d)). A driver who will not consent may not perform a safety-sensitive function (382.703(c)).

If the query shows a violation, the driver may not perform safety-sensitive functions until the Clearinghouse shows the return-to-duty process complete, with follow-up testing done or taken on by the new employer (382.701(d)). The carrier keeps a record of each query and its result for 3 years, and a carrier with a valid Clearinghouse registration meets that through the Clearinghouse (382.701(e)).

A hire produces records for three different files. Mixing them is its own finding.

The qualification file stays for as long as the driver is employed and 3 years after (391.51(c)), and so do the safety performance histories for a driver who is hired (391.53(c)). The whole 391.51 list, with the annual items that come later, is in the driver qualification file checklist.

Section 391.23 runs two 30-day clocks, and they start on different days. The carrier's clock starts on the date the driver's employment begins (391.23(c)(1)). The previous employer's clock starts when it receives the request: it has 30 days to respond, and it must respond even when it has no safety history to report (391.23(g)(1)).

Take a driver whose employment begins Monday, October 19, 2026. The carrier's 30 days end Wednesday, November 18. The carrier mails its request on October 28, and the previous employer receives it Friday, October 30. That employer's 30 days end Sunday, November 29, eleven days after the carrier's. The previous employer can answer on time and still answer too late for the carrier's file.

The rule's answer is the good-faith record. By November 18 the investigation history file holds the replies or documentation of the carrier's good-faith efforts: who was contacted, at what address, when, and what came back (391.23(c)(1), 391.23(c)(2)). A reply that lands on November 25 goes in the same file when it arrives. The fix for the next hire is to send the requests when the application comes in, before the start date: 391.53 covers a new or prospective driver, and the applicant has already been told previous employers will be contacted (391.21(d)).

The other checks run on no 30-day clock at all. The verified negative drug test and the full Clearinghouse query come before the first safety-sensitive function, and the application, the road test and the medical certification come before the first trip. A driver can start inside the 30-day window for 391.23; a driver cannot start before those.
