DOT Record-Keeping Requirements for Motor Carriers

Last reviewed: July 2026

DOT record-keeping requirements do not use one universal retention period. Motor carriers must keep driver qualification, drug and alcohol, hours-of-service, maintenance, inspection, Clearinghouse, and accident records for periods ranging from several months to the duration of employment plus three years. Records may generally be electronic, but they must remain accurate, secure, retrievable, and available when requested.

Detailed maintenance records generally must be kept for one year and for six months after the vehicle leaves the carrier’s control.
Annual inspection reports are generally retained for 14 months, while roadside inspection reports are retained for 12 months.
Electronic storage is permitted when records accurately contain the required information and can be reproduced within the required timeframe.

What Are DOT Record-Keeping Requirements?

DOT record-keeping requirements are the federal rules that tell a motor carrier which compliance documents must be created, how long they must be retained, who may access them, where they may be stored, and how quickly they must be produced.

For most interstate motor carriers, the principal requirements come from several parts of the Federal Motor Carrier Safety Regulations:

49 CFR Part 390 for general records, accidents, record locations, and electronic documents.
49 CFR Part 391 for driver qualification and investigation records.
49 CFR Part 382 for FMCSA drug and alcohol program records and Clearinghouse requirements.
49 CFR Part 395 for records of duty status, ELDs, time records, and supporting documents.
49 CFR Part 396 for vehicle maintenance, inspection, repair, and inspector-qualification records.

The rules that apply to a particular carrier depend on its operation, vehicle types, driver duties, passenger or property service, hazardous-material activity, exemptions, and whether the operation is interstate or intrastate.

Federal retention periods are minimums. A State requirement, insurance policy, contract, tax rule, litigation hold, claim, accident investigation, or company policy may justify keeping a document longer.

How Long Must DOT Records Be Kept?

The correct retention period depends on the type of record and the event that starts the retention clock. The following chart covers major FMCSA record categories but should not be treated as a substitute for reviewing the regulation that applies to the carrier’s operation.

Common FMCSA record-retention periods for motor carriers
Record category	General minimum retention period	Primary authority or important note
General driver qualification file	Throughout employment and for three years afterward	49 CFR 391.51. Certain annual and medical documents may be removed three years after execution.
Driver investigation history file	Throughout employment and for three years afterward	49 CFR 391.53. Must be secured and access-controlled.
Positive drug tests, alcohol results of 0.02 or greater, refusals, SAP evaluation and referral records, program violations, calibration documentation, and required annual summaries	Five years	49 CFR 382.401
Drug and alcohol collection-process records	Two years	49 CFR 382.401, except calibration documentation assigned a different period
Negative and canceled drug-test results, MRO reversals of canceled results, and alcohol results below 0.02	One year	49 CFR 382.401
Drug and alcohol education and training records	While the person performs the regulated function and for two years afterward	49 CFR 382.401
Prior-employer drug and alcohol information obtained under 49 CFR 40.25	Three years	49 CFR 40.333
Clearinghouse query records	Three years	A valid Clearinghouse registration satisfies the federal query-record retention requirement under 49 CFR 382.701.
Clearinghouse consent	Three years from the date of the last query covered by the consent	49 CFR 382.703
Records of duty status and supporting documents	Six months from receipt	49 CFR 395.8 and 395.11
Qualifying short-haul time records	Six months	49 CFR 395.1
ELD backup records	Six months	The backup must be stored on a device separate from the original ELD data.
Vehicle inspection, repair, and maintenance records required by 49 CFR 396.3	One year and for six months after the vehicle leaves the carrier’s control	Detailed records generally apply to vehicles controlled for 30 consecutive days.
Written driver vehicle inspection report listing defects and related repair certifications	Three months	49 CFR 396.11
Annual or periodic inspection report	14 months	49 CFR 396.21
Roadside inspection report	12 months	49 CFR 396.9. Required corrections must generally be certified within 15 days.
Annual inspector qualification evidence	While the person performs annual inspections and for one year afterward	49 CFR 396.19
Brake-inspector qualification evidence	While employed in that capacity and for one year afterward	49 CFR 396.25
Accident register	Three years after the accident	49 CFR 390.15

A carrier should record both the retention period and the disposal date in its retention schedule. “Keep for three years” is not enough unless the company also knows whether that period runs from hiring, execution, receipt, inspection, accident, termination, or another event.

What Records Belong in a Driver Qualification File?

A motor carrier must maintain a driver qualification file for each driver it employs when Part 391 applies. The file documents how the carrier determined that the driver met the applicable qualification requirements.

Common driver qualification file contents

The driver’s completed employment application.
The initial motor vehicle record obtained from each applicable licensing authority.
The road-test certificate or accepted equivalent documentation.
Annual motor vehicle records.
Notes documenting annual reviews of the driver’s driving record.
Required medical-certification or CDLIS medical-status records.
Applicable medical variances or exemptions.
A Skill Performance Evaluation certificate when applicable.
Required notes verifying the medical examiner’s National Registry listing where applicable.

The general driver qualification file may be combined with the driver’s personnel file. However, combining the files does not remove privacy, access-control, or document-production obligations.

TeamCME’s complete DOT driver qualification file checklist provides a more detailed hiring and annual-review workflow.

What belongs in the driver investigation history file?

The safety-performance history obtained from previous employers must be maintained in a separate secure file or access-controlled record area. Access should be limited to people involved in the hiring decision or controlling access to the information, with limited insurer access as permitted by the rule.

The file generally includes:

The driver’s written authorization for the required investigation.
Responses received from prior employers.
Documentation of good-faith efforts when a prior employer does not respond.
The prior employer’s name and address.
The date of contact.
The safety-performance information received.

For a hired driver, this information is retained throughout employment and for three years afterward.

Current medical-certification record note

National Registry II electronically transmits CDL and CLP medical-certification information to State Driver Licensing Agencies. However, a temporary FMCSA exemption currently permits interstate CDL holders, CLP holders, and motor carriers to rely on a paper Medical Examiner’s Certificate for up to 60 days after issuance.

The exemption is effective from April 11 through October 11, 2026. Because this is temporary, carriers should review the current FMCSA National Registry II Learning Center before relying on the paper certificate after that date.

How Long Must DOT Drug and Alcohol Records Be Kept?

FMCSA drug and alcohol testing records must be stored securely with controlled access. The retention period depends on the result, process, or administrative purpose of the record.

Records generally retained for five years

Alcohol-test results showing a concentration of 0.02 or greater.
Verified positive controlled-substance test results.
Documentation of refusals to take a required test.
Driver evaluation and referral records.
Substance Abuse Professional evaluation and compliance records.
Calibration documentation.
Records related to administration of the program, including driver violations.
Required annual calendar-year summaries.

Records generally retained for two years

Documents related to random-selection processes.
Collection logbooks when used.
Documents supporting reasonable-suspicion testing decisions.
Documents supporting post-accident testing decisions.
Collection-process records not assigned another retention period.
Medical documentation concerning an inability to provide sufficient breath, urine, or oral fluid.

Records generally retained for one year

Negative controlled-substance test results.
Canceled controlled-substance test results.
Medical Review Officer reversals of canceled results.
Alcohol-test results below 0.02.

Training records

Training and education records for breath alcohol technicians, screening test technicians, supervisors, and drivers must generally be retained while the individual performs the function requiring that training and for two years afterward.

Clearinghouse records

Employers must retain Clearinghouse query records for three years. A valid Clearinghouse registration satisfies the federal query-record requirement because the system retains the query history.

Consent used for a Clearinghouse query must be kept for three years from the date of the last query covered by that consent. A limited-query consent may cover more than one query when properly written, but the retention period runs from the last query conducted under it.

Motor carriers can review TeamCME’s complete employer guide to DOT drug and alcohol testing requirements.

Do these records have to be separate from personnel files?

The regulation requires a secure location with controlled access. It does not require one specific cabinet, folder color, or software structure.

As a practical privacy safeguard, carriers should restrict access by role and separate sensitive drug, alcohol, medical, and investigation records from routine personnel documents. A compliance system should make it difficult for an unauthorized dispatcher, supervisor, or office employee to view protected information.

How Long Must ELD and Hours-of-Service Records Be Kept?

Motor carriers generally must retain records of duty status and required supporting documents for six months from the date the carrier receives them.

Records of duty status

Depending on the operation, a record of duty status may be created through:

An electronic logging device.
An automatic onboard recording device where still legally permitted.
A paper log when a regulatory exception or ELD malfunction procedure applies.
A qualifying time-record system for a short-haul exception.

Qualifying short-haul time records must also generally be retained for six months.

Supporting documents

Supporting documents can include records generated in the normal course of business that help verify a driver’s on-duty-not-driving time. Depending on the operation, examples may include:

Bills of lading, itineraries, schedules, or equivalent documents.
Dispatch records and trip records.
Expense receipts.
Electronic mobile communication records.
Payroll records and settlement statements.

Drivers generally must submit completed records of duty status and supporting documents to the carrier within 13 days. The carrier must retain the applicable records for six months.

ELD backup requirements

A carrier must retain a six-month backup copy of ELD records on a device separate from the device storing the original records. The storage method should also protect driver privacy and allow the records to be produced in the required format.

An exported spreadsheet or PDF that loses required ELD event data, annotations, edits, certifications, or original-event history may not be an adequate substitute for the required ELD record.

What Are the DOT Maintenance File Requirements?

Motor carriers generally must maintain detailed records for each vehicle they control for 30 consecutive days. The records show the vehicle’s identity, maintenance schedule, inspections, repairs, and other required safety work.

Required maintenance record information

Company vehicle number when one is assigned.
Make, serial number, and model year.
The name of the person furnishing the vehicle when the carrier does not own it.
A method showing the nature and due date of inspection and maintenance work.
The date and nature of inspections, repairs, and maintenance performed.
Required test records for bus emergency exits and related equipment when applicable.

These records generally must be kept where the vehicle is housed or maintained for one year and for six months after the vehicle leaves the carrier’s control.

What does “controlled for 30 consecutive days” mean?

The 30-day rule identifies when the detailed record requirement applies to a vehicle under the carrier’s control. It does not mean that the carrier keeps the records for only 30 days.

Leased and non-owned vehicles may still require maintenance records when the carrier controls them for the applicable period. The file should identify the person or entity furnishing the vehicle.

How Long Must DOT Inspection Records Be Kept?

Inspection records do not all share the same retention period. Annual inspections, driver vehicle inspection reports, roadside inspections, and inspector-qualification records must be tracked separately.

Common DOT inspection records and retention periods
Inspection record	Retention period	Important requirement
Written driver vehicle inspection report listing a defect	Three months	Keep the report, repair certification, and driver-review certification where applicable.
Annual or periodic inspection report	14 months	Keep the report where the vehicle is housed or maintained and make it available on demand.
Roadside inspection report	12 months	Certify correction of violations within 15 days and return the form to the issuing agency when requested.
Annual inspector qualification evidence	During the person’s inspection role and one year afterward	Document the training or experience establishing qualification.
Brake-inspector qualification evidence	During employment in that capacity and one year afterward	Maintain evidence at the principal place of business or the inspector’s work location.

Are no-defect post-trip reports required?

Property-carrying drivers generally do not have to prepare a written driver vehicle inspection report when no defect or deficiency was discovered or reported. When a written report lists a defect, the carrier must address defects that could affect safe operation and retain the required documentation.

Passenger, intermodal-equipment, single-vehicle, and other operations may be subject to different provisions or exceptions. Carriers should apply the subsection that matches their operation rather than using a generic DVIR policy for every fleet.

How Long Must a Motor Carrier Keep an Accident Register?

A motor carrier must generally retain its accident register for three years after the date of each qualifying accident.

The register must contain at least:

The date of the accident.
The city or town and State where it occurred, or the nearest location.
The driver’s name.
The number of fatalities.
The number of injuries.
Whether hazardous materials other than fuel spilled from the vehicle were released.

The carrier should also preserve copies of accident reports required by a State, another government entity, or an insurer when those reports are required under the applicable rule.

A carrier should suspend routine destruction when an accident, claim, subpoena, investigation, enforcement matter, or lawsuit creates a legal-hold obligation. A federal minimum retention period is not permission to destroy relevant evidence during a pending matter.

Can DOT Records Be Stored Electronically?

Yes. FMCSA generally permits electronic records and signatures when the electronic document accurately reflects the required information, can be retained, and can be reproduced within the required timeframe.

An acceptable electronic record system should:

Preserve all required information.
Keep records for the full retention period.
Allow authorized users to retrieve records promptly.
Protect confidential information through access controls.
Preserve signatures, certifications, dates, and required attachments.
Prevent undocumented overwriting or deletion.
Produce legible copies for an auditor or enforcement official.
Maintain backups and disaster-recovery procedures.

A scanned file is not compliant merely because it exists. An unreadable scan, broken link, inaccessible former-employee account, expired vendor portal, or database export that omits required fields can leave the carrier unable to produce the required record.

How quickly must records be produced?

When records are kept at a regional office or driver work-reporting location, FMCSA may require them to be produced at the carrier’s principal place of business or another specified location within 48 hours after a request. Saturdays, Sundays, and federal holidays are excluded when calculating that period.

Some regulations contain their own production rules. For example, Part 382 drug and alcohol records must be available at the principal place of business within two business days after an authorized FMCSA request.

How Should a Motor Carrier Organize DOT Records?

A reliable recordkeeping system assigns an owner, retention period, access level, and disposal date to every record category.

Identify which regulations apply.Document the carrier’s interstate or intrastate status, vehicle classes, passenger or property operations, CDL drivers, hazardous-material activity, exemptions, and leased equipment.
Create a record inventory.List every required record, the department that creates it, its legal authority, retention trigger, minimum period, storage location, and responsible employee.
Separate records by function.Use distinct categories for driver qualification, investigation history, drug and alcohol testing, Clearinghouse records, hours of service, maintenance, inspections, accidents, and training.
Apply role-based access.Limit sensitive drug, alcohol, medical, and investigation records to personnel with a legitimate compliance need.
Use standardized names and indexes.Include the driver or vehicle identifier, document type, relevant date, and expiration or destruction date.
Set expiration alerts.Automate reminders for annual MVRs, medical-status checks, annual inspections, training renewals, expiring variances, and other recurring obligations.
Preserve the original data.Do not replace an original ELD event, testing document, or signed certification with a summary that omits required information.
Test record retrieval.Run a mock request and confirm that staff can produce a complete driver, vehicle, or testing file within the applicable timeframe.
Use a documented destruction process.Destroy records only after the minimum period has expired and after checking for active claims, legal holds, audits, agency requests, and longer non-FMCSA obligations.
Review the schedule when rules change.Assign a compliance owner to review eCFR changes, FMCSA notices, temporary exemptions, and State requirements.

Who Should Be Responsible for Each Record Category?

Suggested ownership of motor-carrier compliance records
Record category	Typical internal owner	Control to verify
Driver qualification files	Safety, compliance, or qualified HR personnel	Hiring documents, annual reviews, medical status, variances, and expiration alerts
Driver investigation history	Restricted hiring or compliance staff	Controlled access and documented prior-employer inquiries
Drug and alcohol testing	Designated employer representative	Privacy, retention category, reporting, and return-to-duty documentation
Clearinghouse queries	Employer or designated C/TPA	Pre-employment and annual queries, consent, and prohibited-status controls
Hours of service and ELD records	Safety, dispatch, or logs department	Driver submissions, edits, annotations, certifications, supporting records, and backup
Maintenance and inspection	Fleet maintenance manager	Vehicle identity, schedules, repairs, inspection reports, and inspector qualifications
Accident register	Safety, claims, or risk management	Register completeness, report preservation, and legal holds

Assigning a vendor, C/TPA, maintenance shop, ELD provider, or records company does not automatically eliminate the motor carrier’s responsibility to ensure that required records exist and can be produced.

DOT Record-Keeping Checklist Before an FMCSA Audit

Confirm that every regulated driver has a complete qualification file.
Confirm that annual MVRs and annual review notes are current.
Verify current medical-certification status and applicable variances.
Restrict access to driver investigation, drug, alcohol, and medical records.
Confirm pre-employment and annual Clearinghouse queries.
Match Clearinghouse consents to the queries they support.
Confirm random-selection, reasonable-suspicion, post-accident, and testing records are complete.
Check that drug and alcohol records are assigned to the correct retention category.
Review six months of logs, time records, and supporting documents.
Verify that the ELD backup is maintained separately from the original data.
Confirm maintenance files for every vehicle controlled for 30 consecutive days.
Check annual inspection reports and expiration dates.
Retain roadside inspection reports for 12 months and verify correction certifications.
Verify annual and brake-inspector qualification records.
Review the three-year accident register.
Test whether records can be retrieved and produced within the applicable deadline.
Confirm that no records subject to an audit, claim, or legal hold are scheduled for destruction.

Common DOT Record-Keeping Mistakes

Using one retention period for an entire department

Drug and alcohol, inspection, qualification, and maintenance files contain documents with different retention periods. A department-wide “keep everything for three years” rule can cause both premature destruction and unnecessary retention.

Counting from the wrong date

Some periods begin on the execution date, others on receipt, inspection, accident, last query, termination, or the date a person stops performing a regulated function.

Treating 30 days as the maintenance retention period

The 30-consecutive-day provision generally triggers the detailed vehicle-record requirement. The required maintenance records are kept much longer.

Keeping every driver document in one unrestricted personnel file

General driver qualification records may be combined with personnel records, but investigation, drug, alcohol, medical, and other sensitive records require appropriate access restrictions.

Assuming a vendor will preserve records indefinitely

Contracts with ELD providers, C/TPAs, laboratories, clinics, and maintenance vendors should explain data ownership, exports, retention, access after termination, and audit support.

Deleting original ELD data after creating a summary

A summary may omit edits, original events, annotations, certifications, location information, and other required elements. Preserve the required original and backup data.

Retaining only inspection stickers

A decal may show that an inspection occurred, but the responsible party may still need the inspection report or the ability to obtain it on demand.

Missing the roadside inspection response deadline

Roadside defects must be addressed, and the carrier generally has 15 days to certify the corrections and return the report when the issuing agency requests it.

Automatically destroying records when the minimum period ends

Pause destruction when records are relevant to litigation, a claim, an accident, an investigation, a subpoena, an agency request, or another legal obligation.

What Should a Motor Carrier Do Next?

Compare the company’s retention chart with the current eCFR.
Correct any policy that treats the 30-day vehicle-control rule as a retention period.
Separate sensitive investigation and testing records through access controls.
Add Clearinghouse query and consent records to the retention schedule.
Confirm that ELD backups are stored separately from the original data.
Audit annual, roadside, and defect inspection records as separate categories.
Add the accident register to the central compliance index.
Test a 48-hour record-production exercise.
Assign an owner to monitor temporary NRII requirements through October 11, 2026.
Document a legal-hold and secure-destruction process.

Frequently Asked Questions

How long does the DOT require records to be kept?

There is no single DOT retention period. Common periods range from three months for certain written vehicle inspection reports to the duration of a driver’s employment plus three years for general qualification files. The applicable regulation and the event that starts the retention period must be identified for each record.

What records must be in a DOT driver qualification file?

A driver qualification file generally includes the employment application, initial and annual motor vehicle records, road-test documentation or an accepted equivalent, annual review notes, required medical-certification information, applicable variances, and National Registry verification records where required.

How long do motor carriers have to keep DOT inspection records?

Written driver vehicle inspection reports listing defects are generally kept for three months, annual inspection reports for 14 months, and roadside inspection reports for 12 months. Annual and brake-inspector qualification evidence is kept while the person performs that work and for one year afterward.

Can DOT records be stored electronically?

Yes. Electronic records and signatures are generally permitted when the documents accurately contain the required information, remain available for the full retention period, and can be accurately reproduced within the required timeframe for an authorized party.

Must DOT drug and alcohol records be separate from personnel files?

Part 382 requires secure storage with controlled access but does not prescribe one physical filing arrangement. Separating sensitive testing records through restricted folders or role-based electronic permissions is a strong privacy and compliance practice.

What is a DOT records check?

The phrase can refer to several different reviews, including an employer’s motor vehicle record inquiry, an FMCSA Drug and Alcohol Clearinghouse query, a Pre-Employment Screening Program report, a driver qualification file audit, or an FMCSA review of carrier records. The requester should identify which record system and legal authority apply.

Do DOT violations go on a driver’s record?

There is no single universal DOT record. Convictions and licensing actions may appear on a State motor vehicle record, FMCSA-reportable crashes and roadside inspections may appear in a PSP report, carrier inspection and crash data may affect FMCSA safety systems, and drug or alcohol program violations are recorded in the Clearinghouse.

How long must ELD logs and supporting documents be kept?

Motor carriers generally must retain records of duty status, required supporting documents, and qualifying short-haul time records for six months. A six-month backup of ELD records must be stored on a device separate from the original data.

Must drivers submit supporting documents to the carrier within 13 days?

Yes, drivers subject to the applicable record-of-duty-status rule generally must submit completed records of duty status and supporting documents to the motor carrier within 13 days. The carrier then retains the required records for at least six months.

Do owner-operators have DOT record-keeping requirements?

Yes. An owner-operator may have both driver and motor-carrier or employer responsibilities. The exact records depend on the operation, vehicle, authority, testing arrangement, exemptions, and whether a consortium or third-party administrator performs specific drug and alcohol program functions.

Educational and Regulatory Disclaimer

This resource provides general educational information about federal motor-carrier recordkeeping. It does not replace the current Federal Motor Carrier Safety Regulations, State requirements, agency interpretations, contractual obligations, insurance requirements, tax rules, or individualized legal advice. Requirements vary by operation and may change. Motor carriers should verify the current rule and consult a qualified compliance or legal professional when applying a retention period to a specific record.
