Quick Summary

A truck driver qualification file, also called a driver qualification file or DQ file, is a collection of records a motor carrier generally must maintain to document that a commercial driver meets federal qualification requirements.

A DQ file can include the driver’s employment application, motor vehicle records, road-test documentation, annual driving-record reviews, and required medical qualification records.

After a truck accident, these records may help determine whether the trucking company properly screened, qualified, and monitored the driver before allowing that person to operate a commercial vehicle.

However, a DQ file is generally not a public record. An accident victim may request it directly, but the trucking company may not voluntarily provide the complete file. It is commonly obtained through formal discovery after a lawsuit is filed.

What Is a Truck Driver Qualification File?

A driver qualification file is a regulatory record maintained by a motor carrier for each driver it employs.

Under 49 C.F.R. § 391.51, a motor carrier must maintain a qualification file for each driver. The regulation also permits the carrier to combine the DQ file with the driver’s personnel file.

The file is more than ordinary hiring paperwork. It is intended to document whether the carrier obtained and reviewed the records necessary to determine whether the driver was qualified to operate a commercial motor vehicle.

After a serious truck crash, the file may help answer questions such as:

Was the driver properly licensed?
Did the carrier obtain the driver’s motor vehicle record?
Did the driver complete a required road test?
Did the company review the driver’s record annually?
Was the driver medically qualified?
Did the carrier overlook suspensions, restrictions, or serious violations?
Did required documents expire before the crash?

These questions can become important when investigating whether the carrier negligently hired, retained, assigned, or supervised the driver.

What Does a Truck Driver Qualification File Contain?

The exact contents can depend on the driver’s licensing status, the type of operation, and whether an accepted exception or equivalent document applies.

A DQ file generally contains the following records.

1. The Driver’s Employment Application

The file must generally include the driver’s completed employment application.

A commercial-driver application may contain information about:

Previous employers
Commercial driving experience
Licenses held
Traffic convictions
License suspensions
Prior crashes
Types of trucks or trailers previously operated

The application may be compared with motor vehicle records and other employment information.

Potential warning signs can include:

Omitted trucking employers
Inconsistent employment dates
Undisclosed license suspensions
Missing crash information
Experience that does not match the assigned vehicle
Materially false or incomplete answers

An inaccurate application does not automatically establish that the carrier caused a later accident. It may, however, raise questions about whether the company adequately investigated the driver before hiring or assigning that person.

2. The Initial Motor Vehicle Record

A motor carrier generally must obtain a motor vehicle record from each applicable driver-licensing authority covering the driver’s prior three-year driving history.

The record obtained through that initial inquiry must be placed in the driver qualification file.

Depending on the available information, a motor vehicle record may identify:

License status
Commercial driver’s license status
Endorsements and restrictions
Traffic convictions
Suspensions or revocations
Certain serious driving violations
Medical-certification status for applicable CDL holders

This record may help establish what information was available to the carrier when the driver’s employment began.

A single old violation does not necessarily make a driver unqualified. The type, frequency, timing, and seriousness of the driver’s history must be evaluated in context.

3. Road-Test Documentation or an Accepted Equivalent

A motor carrier generally must confirm that the driver can safely operate the type of commercial vehicle assigned to that driver.

The DQ file may contain:

A certificate showing completion of a road test
A copy of a license or certificate accepted as an equivalent
Other documentation permitted under an applicable federal provision

Under 49 C.F.R. § 391.31, a road test may evaluate skills such as:

Pre-trip inspection
Coupling and uncoupling equipment, when applicable
Placing the vehicle in operation
Use of controls and emergency equipment
Operating in traffic
Turning
Braking and slowing
Backing and parking

Road-test documents may be particularly relevant when a crash involves improper backing, poor braking, a wide turn, loss of control, or an unsafe lane change.

A signed road-test certificate does not necessarily prove that the driver received adequate training. Investigators may still examine who administered the test, the vehicle used, the skills evaluated, and whether the test reflected the driver’s actual assignment.

4. Annual Motor Vehicle Records

A carrier generally must obtain updated motor vehicle records for its drivers at least once during each 12-month period.

These records may reveal problems that developed after the driver was hired, such as:

New traffic convictions
License suspensions
Restrictions or disqualifications
Serious commercial-driving violations
Changes in medical-certification status
A pattern of unsafe driving

The annual records can help determine whether the company remained informed about the driver’s qualifications.

5. Notes Documenting the Annual Driving-Record Review

Obtaining an updated driving record is only part of the requirement. The motor carrier must also review the record and document that review.

The annual-review note may help answer:

Did the carrier identify new violations?
Did the company evaluate whether the driver remained qualified?
Was retraining or discipline considered?
Did the company continue assigning the driver after repeated safety problems?
Was the annual review completed on time?
Does the note appear to reflect an actual review?

A signed form alone may not establish that a meaningful evaluation occurred. Other company records may show whether the carrier took action in response to a driver’s changing safety history.

6. Medical Qualification Documentation

Commercial drivers operating under applicable federal rules must meet physical qualification requirements.

Depending on the driver, the DQ file may contain:

A medical examiner’s certificate
A legible copy of that certificate
A CDLIS motor vehicle record showing medical-certification status
Documentation of a medical variance
A Skill Performance Evaluation certificate
A qualifying federal medical exemption
A required note verifying the medical examiner’s National Registry listing

These records may show whether the driver held valid medical certification on the date of the crash.

A DQ file does not ordinarily contain the driver’s entire medical history. Detailed medical records, treatment information, or medication history may require a separate factual basis and formal legal process. Privacy protections, redactions, and court-imposed limitations may apply.

7. Applicable Variances or Exemptions

Some commercial drivers may operate under a medical variance, Skill Performance Evaluation certificate, or federal exemption.

The relevant documentation can help determine:

Whether the authorization was current
Whether it applied to the driver’s condition
Whether the driver complied with its limitations
Whether the carrier verified the document
Whether the assigned vehicle or operation was permitted

Operating under a valid variance does not mean that the driver was unsafe. The issue is whether the driver and carrier complied with the applicable terms.

Are Prior-Employer Investigations Part of the DQ File?

Generally, no.

This is an important distinction.

Under 49 C.F.R. § 391.23, a prospective motor carrier generally must investigate a driver’s safety-performance history with Department of Transportation-regulated employers from the preceding three years.

However, the responses to those investigations are generally placed in a separate driver investigation history file, not the standard driver qualification file.

That separate file can include information about:

Prior DOT-regulated employment

Accidents involving the driver

Safety-performance history

Documented attempts to contact former employers

Certain drug and alcohol testing history

Driver correction or rebuttal statements

The driver investigation history file is subject to specific confidentiality and access rules.

Because the files are separate, a truck accident investigation should not ask only for the “DQ file.” The request may also need to identify the driver investigation history file and other related employment records.

How Is a DQ File Different From Other Trucking Records?

A commercial driver’s records may be divided among several files, departments, and electronic systems.

Record	What it generally addresses
Driver qualification file	Whether the driver met applicable qualification requirements
Driver investigation history file	Prior-employer safety-performance investigations
Personnel file	Broader employment, attendance, pay, complaints, discipline, and performance information
Training file	Initial, recurrent, remedial, and vehicle-specific training
Drug and alcohol records	Testing, Clearinghouse, return-to-duty, and follow-up compliance
ELD records	Driving time, on-duty time, rest periods, and hours-of-service compliance
Electronic control module data	Potential speed, braking, throttle, and vehicle-event information
Maintenance file	Inspections, repairs, defects, and service history
Dispatch records	Assignments, routes, delivery expectations, and communications

A request limited to the folder labeled “DQ file” may therefore miss important evidence stored elsewhere.

How Long Must a Trucking Company Keep a DQ File?

A motor carrier generally must retain the driver qualification file for as long as the driver is employed and for three years after the employment relationship ends.

However, certain documents may be removed three years after the date they were created. These may include:

Annual motor vehicle records
Annual-review notes
Medical examiner’s certificates
CDLIS records obtained for medical-certification purposes
Medical variances
Skill Performance Evaluation certificates
Medical-exemption documents
Certain National Registry verification notes

This record-specific rule makes timing important.

A company may routinely update, archive, or remove older documents under its retention system. Other evidence, such as video, telematics, ELD data, or internal communications, may have shorter practical retention periods.

A prompt preservation notice can place the carrier on notice that relevant evidence should not be destroyed, altered, overwritten, or discarded.

Why Does a DQ File Matter After a Truck Accident?

The police report may explain what happened at the scene. A DQ file may help explain why the driver was operating the truck in the first place.

It May Reveal Negligent Hiring

Negligent hiring may become an issue when a carrier fails to use reasonable care in selecting a commercial driver.

Relevant concerns may include:

Failure to obtain a required driving record
Ignored license restrictions
Repeated serious violations
Material inconsistencies in the application
Inadequate road testing
Assignment to equipment beyond the driver’s demonstrated experience

The prior conduct must have a meaningful connection to the hiring decision and the issues presented by the crash. Not every mistake or old violation proves negligent hiring.

It May Reveal Negligent Retention

A driver may appear qualified when hired but develop safety problems later.

Annual driving records and reviews may show that the company learned about:

New violations
License problems
Repeated preventable crashes
Out-of-service events
Medical-certification issues
A pattern of unsafe conduct

Investigators can then determine whether the company appropriately retrained, disciplined, reassigned, suspended, or removed the driver from service.

It May Reveal Inadequate Monitoring

A carrier may collect the required documents without meaningfully acting on them.

Potential warning signs include:

Late annual reviews
Identical or formulaic review notes
No response to repeated violations
Expired documents
Missing signatures
Records created after the crash
Conflicting dates
Incomplete qualification information

A missing or incomplete document does not automatically prove negligence. It may nevertheless justify further investigation into the carrier’s compliance and safety practices.

Is a Driver Qualification File Public?

Generally, no.

A DQ file is maintained by the motor carrier. It is not ordinarily available through a public FMCSA search portal.

An accident victim may ask the carrier or its insurer to produce the file. The company may:

Refuse the informal request
Provide only selected records
Redact personal information
Assert privacy or confidentiality objections
Argue that some materials are irrelevant
Require formal litigation discovery

Federal recordkeeping regulations permit government regulators and authorized representatives to inspect required records. They do not ordinarily give every member of the public an unrestricted right to obtain a commercial driver’s complete file.

Can an Accident Victim Get a DQ File?

An accident victim can request the file, but a written request alone may not require the carrier to produce it.

The most reliable process usually involves:

Identifying the correct carrier and related companies.
Sending a prompt evidence-preservation notice.
Requesting voluntary production.
Filing a lawsuit when appropriate.
Serving formal requests for production.
Using subpoenas for relevant records held by nonparties.
Asking the court to resolve valid discovery disputes when necessary.

How Do You Get a Truck Driver Qualification File?

Step 1: Identify the Correct Motor Carrier

Begin by determining which legal entity employed or controlled the driver.

Useful evidence may include:

The Louisiana crash report
The USDOT number displayed on the truck
Photographs from the accident scene
Names printed on the cab and trailer
Vehicle-registration records
Insurance correspondence
Shipping documents
Bills of lading
Driver statements

The company name printed on the truck may be a trade name rather than the carrier’s complete legal name. The tractor, trailer, driver, and cargo may also be connected to different businesses.

Step 2: Send a Preservation Notice

A preservation notice should identify the collision, the vehicles, the driver, and the categories of evidence that must be retained.

Depending on the case, it may identify:

The complete DQ file
The driver investigation history file
Personnel and disciplinary records
Training and evaluation records
Motor vehicle records
Road-test documents
Medical qualification records
ELD data
GPS and telematics data
Dash-camera video
Dispatch communications
Inspection and maintenance records
Post-crash testing records
Internal crash investigations

A preservation notice is not a subpoena or court order. It does not automatically force the carrier to provide the evidence.

Its purpose is to put the carrier on notice that relevant information should be preserved. Whether later evidence loss supports sanctions or another court remedy depends on the facts, the applicable preservation duty, and the governing procedural rules.

Step 3: Request Voluntary Production

An injured person or attorney may submit a written request to the carrier or insurer before filing suit.

The request should identify:

The driver
The carrier
The crash date and location
The truck and trailer
The police-report number
Each requested category of records

A precise request is generally better than asking only for “the driver’s file.”

Step 4: Use Formal Discovery

After a lawsuit is filed, the carrier can be served with formal requests for production.

The request may separately identify:

DQ-file documents
Driver investigation history records
Training materials
Disciplinary records
Internal safety records
Electronic evidence
Maintenance and inspection files

The trucking company may raise objections concerning scope, relevance, privacy, medical information, confidentiality, or burden.

The parties may resolve those issues through tailored requests, redactions, confidentiality agreements, or a protective order. A court may decide unresolved disputes.

Step 5: Subpoena Relevant Third Parties

Some documents may be held by entities other than the defendant carrier.

Possible record custodians include:

Previous employers
Staffing agencies
Driver-training schools
Licensing authorities
Medical examiners
Background-screening companies
Testing administrators
Telematics vendors

A subpoena, authorization, or court order may be necessary, depending on the record and the entity holding it.

Can You Get the File From FMCSA?

Usually, FMCSA is not the source of a carrier’s complete driver qualification file.

FMCSA establishes and enforces federal motor-carrier safety rules. The carrier generally remains the custodian of the DQ file.

Public FMCSA resources may still help identify:

The carrier’s legal name
Its USDOT number
Operating status
Inspection information
Out-of-service data
Available crash or enforcement information

Those records can provide useful investigative leads, but they do not replace the carrier’s complete DQ file.

What Should You Look for in a DQ File?

A proper review involves more than checking whether forms are present.

Was the record created before the crash?

A document created after the accident may not establish what the carrier knew beforehand.

Are the dates consistent?

Check for expired certificates, late annual reviews, unusual signatures, unexplained gaps, and records that appear to have been completed out of sequence.

Does the application match independent records?

Compare the driver’s application with licensing records, employment information, prior crash history, and other available evidence.

Did the company act on warning signs?

Determine whether violations or qualification problems resulted in meaningful review, discipline, retraining, reassignment, or removal from service.

Was the driver qualified for the actual assignment?

A driver may hold a valid CDL but lack adequate experience with a particular vehicle configuration, trailer, load, route, or operating condition.

Are other records stored separately?

Qualification, training, personnel, safety, dispatch, and electronic records may be located in different systems or held by different companies.

What Happens if the DQ File Is Missing or Incomplete?

A missing document may indicate a recordkeeping problem, but it does not automatically establish liability.

The investigation should determine:

Whether the document was required
Whether it ever existed
Who was responsible for maintaining it
Whether it was removed under a lawful retention policy
Whether the carrier had already received notice to preserve it
Whether it was destroyed after a preservation duty arose
Whether the information is available from another source
Whether the missing information relates to the cause of the crash

The legal significance of lost evidence depends on the facts, the applicable law, and the court’s findings.

Does a Missing DQ Record Automatically Prove a Truck Accident Claim?

No.

A regulatory violation or missing record may be relevant evidence, but a claimant generally must still establish the elements required under applicable law.

That analysis may include whether:

The carrier failed to comply with a duty.
The driver was unqualified or inadequately monitored.
The failure contributed to the crash.
The crash caused injuries and compensable losses.

For example, a late annual review may show weak compliance. Investigators must still determine whether a timely review would have revealed information connected to the accident.

How Is This Different From Other FMCSA Violations?

A DQ-file investigation focuses on the driver’s qualifications and the motor carrier’s screening and review process.

Our guide to common FMCSA violations that can cause truck accidents addresses broader safety issues, such as:

Hours-of-service violations
Distracted driving
Speeding
Unsafe lane changes
Inspection failures
Brake and tire defects
Cargo-securement problems
Drug and alcohol violations
Commercial-license violations

How Our Legal Team Reviews Driver Qualification Evidence

In a truck accident investigation, qualification records should rarely be reviewed in isolation.

Our legal team may compare the DQ file with:

Licensing records
Driver investigation history records
Training materials
Disciplinary records
Dispatch assignments
Prior crash information
ELD and telematics data
Inspection and maintenance files
Witness statements
Physical and electronic crash evidence

Comparing these sources can help determine what the carrier knew, when it learned it, and whether the company responded appropriately.

Frequently Asked Questions

What does DQ stand for in trucking?

DQ stands for driver qualification. A DQ file is the carrier’s collection of required records documenting a commercial driver’s qualifications.

Does every truck driver have a DQ file?

The requirement depends on whether the driver and carrier are subject to the applicable federal qualification rules. Exceptions and special provisions may apply.

Who maintains the DQ file?

The motor carrier that employs the driver generally maintains it.

Is a DQ file the same as a personnel file?

No. A DQ file focuses on federal qualification requirements. A personnel file may include pay, attendance, evaluations, complaints, discipline, and other employment information. A carrier may combine the two files.

Is the prior-employer investigation kept in the DQ file?

Generally, no. Prior-employer safety-performance investigation responses are typically placed in a separate driver investigation history file.

Can I request a DQ file without an attorney?

Yes. You can send a written request and preservation notice. However, the trucking company may not voluntarily provide the complete file, and an informal letter does not compel production.

Will a preservation letter give me access to the file?

No. A preservation letter asks the carrier to retain the evidence. It does not automatically require the company to produce it.

Can the trucking company redact documents?

Potentially. Personal identifiers, medical information, confidential records, and unrelated information may be redacted or produced under a protective order.

How soon should the file be preserved?

As soon as reasonably possible after a serious truck accident. Some records may be removed under retention schedules, while electronic evidence can be overwritten or lost.

Can the DQ file prove negligent hiring?

It may provide evidence relevant to negligent hiring, retention, supervision, or qualification. Whether it proves a claim depends on the complete facts and applicable law.

Is a DQ file the only evidence needed?

No. A thorough investigation may also require ELD data, dash-camera video, telematics, dispatch records, training files, maintenance records, inspection documents, and other evidence.
