There is no single DOT rule requiring every trucking record to be kept for the same number of years.
The correct retention period depends on:
- record type;
- driver status;
- vehicle status;
- event date;
- testing result;
- carrier operation;
- hazardous-material activity;
- whether the carrier still employs the driver;
- whether the carrier still controls the vehicle.
A carrier that applies one blanket rule—such as “keep everything for three years”—can delete records too early.
It can also retain sensitive records indefinitely without a reason, increasing:
- privacy exposure;
- storage confusion;
- audit retrieval time;
- litigation risk.
The practical solution is a written retention schedule that identifies:
- the regulatory source;
- the trigger date;
- the minimum retention period;
- the deletion date;
- any legal hold or extended business need;
- the person responsible for final deletion.
DOT record-retention quick-reference table
The table below summarizes common federal periods for ordinary interstate motor carriers.
Special operations can require additional records.
| Record | General minimum period | Primary rule |
|---|---|---|
| Accident register | 3 years after each qualifying accident | § 390.15 |
| Driver application | Employment plus 3 years | § 391.51 |

Start with the event that triggers retention
A retention period is meaningless without the correct starting date.
Examples:
- accident register: accident date;
- RODS: date the carrier receives the record;
- annual MVR: execution or review date;
- periodic inspection report: inspection date;
- DVIR: initial report date;
- driver application: employment and termination dates;
- maintenance file: date vehicle leaves carrier control;
- drug test: result or record date;
- hazmat training: employment and latest training cycle.
Calendar-year storage can create mistakes
Suppose a periodic inspection occurred on March 10, 2026.
A “keep through 2027” label is too vague.
The 14-month regulatory period extends through approximately May 10, 2027.
The carrier should store:
- document date;
- trigger type;
- regulatory period;
- calculated minimum deletion date.
Where DOT records must be kept
A carrier with multiple locations can maintain records at:
- principal place of business;
- regional office;
- driver work-reporting location;
- controlled electronic system.
When FMCSA requests records maintained elsewhere, they generally must be made available at:
- the principal place of business;
- or another location specified by the authorized representative
within 48 hours after the request.
Saturdays, Sundays and federal holidays are excluded from the calculation under FMCSA guidance.
Two-day production is not two-day creation
The carrier must already possess the required records.
The 48-hour period allows production from another location.
It does not allow the carrier to:
- reconstruct missing logs;
- obtain overdue MVRs;
- create a maintenance history;
- backdate inspections;
- ask a vendor to invent documents.
Electronic records are permitted
DOT and FMCSA records can generally be maintained electronically when the copies are:
- readily accessible;
- legible;
- identifiable;
- reproducible;
- protected from loss or alteration.
Electronic storage should preserve the required information rather than only a visual summary.
Practical electronic controls
Use:
- company-controlled account;
- role-based access;
- automatic backup;
- version history;
- retention labels;
- file naming;
- export testing;
- deletion approval;
- audit index.
Avoid screenshots as the only record
A screenshot can omit:
- metadata;
- signatures;
- additional pages;
- edit history;
- original data fields;
- transmission details.
Retain the original export or source document where possible.
Accident records
A motor carrier must maintain an accident register for three years after each accident that falls within the federal definition.
The register generally includes:
- date;
- city or nearest city;
- state;
- driver name;
- number of injuries;
- number of fatalities;
- whether hazardous materials other than vehicle fuel were released.
The carrier also maintains copies of accident reports required by:
- state government;
- other governmental entities;
- insurer.
Preserve more than the minimum after a serious crash
A three-year regulatory period does not determine the legal value of:
- dash-camera footage;
- ELD data;
- dispatch messages;
- maintenance records;
- driver file;
- photographs;
- claim correspondence.
When a claim or lawsuit is reasonably anticipated, stop routine destruction of relevant information.
Accident retention file
- Accident register entry
- Police and government reports
- Insurer reports and correspondence
- Photographs and video
- ELD and telematics data
- Driver qualification file snapshot
- Maintenance and inspection records
- Bill of lading and dispatch records
- Post-accident testing analysis
- Legal hold documented where appropriate
Driver qualification records
The driver qualification file is generally retained throughout employment and for three years after employment ends.
However, some recurring documents can be removed three years after execution or issuance.
Employment plus three years
Common records retained for employment plus three years include:
- driver application;
- road-test certificate or accepted equivalent;
- prior-employer safety-performance investigation history.
Three years from execution or issuance
Common recurring records include:
- annual MVR;
- annual-review note;
- medical qualification evidence;
- required CDLIS MVR;
- medical examiner verification note;
- certain current variance evidence.
The carrier should preserve enough current information to prove qualification throughout employment.
Separate investigation-history file
Prior-employer investigation records contain restricted information.
Maintain:
- driver authorization;
- requests;
- responses;
- correction requests;
- rebuttals;
- contact notes
in a controlled file for employment plus three years.
Termination date matters
Record the exact date employment or the driving relationship ended.
Do not start post-employment retention from:
- final payroll processing date;
- last settlement date;
- date the file was closed;
- date the truck was returned
unless that is also the actual employment termination date.
| Record group | Recommended retention trigger |
|---|---|
| Application and road test | Driver termination date plus 3 years |
| Prior-employer investigation | Driver termination date plus 3 years |
| Annual MVR and review | Execution date plus 3 years |
| Medical evidence | Issuance or execution date plus 3 years |
| Current license and qualification status | Maintain current evidence while driver remains active |
Drug and alcohol testing records
Part 382 uses several retention periods.
These records must be stored in a secure location with controlled access.
Five-year records
Maintain for at least five years:
- alcohol results of 0.02 or greater;
- verified positive controlled-substance results;
- test refusals;
- driver evaluations and referrals;
- calibration documentation;
- records related to program administration and violations;
- required annual summaries.
Two-year records
Maintain records related to the collection process for at least two years, except where a different period applies.
Examples can include:
- collection documents;
- random-selection records;
- reasonable-suspicion testing decisions;
- post-accident testing decisions;
- specimen-related medical explanations.
One-year records
Maintain for at least one year:
- negative controlled-substance results;
- cancelled controlled-substance tests;
- qualifying MRO reversals;
- alcohol results below 0.02.
Training records
Education and training records are generally retained while the person performs the function requiring the training and for two years afterward.
This can involve:
- supervisor reasonable-suspicion training;
- breath alcohol technician training;
- driver education materials and signed receipts.
C/TPA does not remove carrier responsibility
The carrier should retain or be able to obtain:
- testing agreements;
- random-pool evidence;
- test records;
- annual summaries;
- collection documentation;
- policy;
- responsible-official information.
Do not let the C/TPA’s contract end before exporting required records.
Clearinghouse records
The Clearinghouse maintains a history of employer full and limited queries.
The carrier can retain separate copies, but the system history can satisfy part of the recordkeeping requirement.
The employer must retain written consent for limited queries for three years.
The consent does not have to be stored in the DQ file, but it must be available when requested.
Keep evidence of the full compliance process
Maintain:
- limited-query consent;
- full-query electronic consent status;
- query date;
- driver identity;
- result;
- action taken;
- C/TPA involvement.
The annual query requirement is separate from the three-year consent retention period.
Hours-of-service records
The carrier must retain records of duty status and required supporting documents for at least six months from the date of receipt.
The six-month period covers:
- ELD records;
- paper logs where permitted;
- qualifying time records;
- supporting documents.
Supporting documents
Examples include:
- bills of lading;
- dispatch records;
- fuel receipts;
- toll records;
- expense receipts;
- electronic communications;
- payroll or settlement records.
The supporting-document rules determine which documents are required and how they are submitted.
Separate ELD backup
The carrier must retain a backup copy of ELD records for six months on a device separate from the original storage system.
The backup requirement matters when:
- provider account is cancelled;
- vendor suffers an outage;
- data is corrupted;
- subscription changes;
- driver account is deactivated.
Driver’s seven-day possession rule
The carrier’s six-month retention rule is different from the driver’s requirement to have the previous seven consecutive days available while on duty.
Do not confuse the two.
Six months may be insufficient for other purposes
Longer storage can be sensible when logs relate to:
- accident;
- wage claim;
- detention dispute;
- insurance investigation;
- tax issue;
- pending enforcement.
HOS retention controls
- RODS retained for at least 6 months
- Supporting documents retained for at least 6 months
- Separate ELD backup retained for 6 months
- Driver accounts preserved after deactivation
- Exports tested regularly
- Unidentified driving retained and resolved
- Paper-log exceptions documented
- Short-haul time records retained
- Accident-related logs placed on legal hold
Vehicle maintenance and inspection records
Vehicle records use several different periods.
Section 396.3 maintenance file
For a vehicle controlled for 30 consecutive days or more, the carrier generally retains the required vehicle maintenance record:
- for one year where the vehicle is housed or maintained;
- and for six months after the vehicle leaves carrier control.
The file includes:
- identification;
- maintenance schedule;
- due dates;
- inspections;
- repairs;
- maintenance history.
DVIRs
Applicable driver vehicle inspection reports, repair certifications and driver-review certifications are generally retained for three months from the report date.
For ordinary property carriers, a written no-defect post-trip DVIR is generally not federally required.
Retain a report when the rule requires one.
Roadside inspection reports
The carrier generally retains the roadside inspection report for 12 months.
It should also preserve:
- repair evidence;
- certification;
- return submission;
- out-of-service resolution.
Periodic inspection reports
The periodic inspection report is generally retained for 14 months from the inspection date.
Evidence of the most recent inspection must also be available on the vehicle.
Inspector qualifications
Evidence of periodic inspector and brake inspector qualification is generally retained while the person performs the function and for one year afterward.
| Vehicle document | Retention |
|---|---|
| Vehicle maintenance file | 1 year while controlled, plus 6 months after control ends |
| Applicable DVIR | 3 months |
| Roadside inspection report | 12 months |
| Periodic inspection report | 14 months |
| Inspector qualification | Function period plus 1 year |
Hazardous-material records
Hazmat operations add separate recordkeeping requirements.
Training records
A hazmat employer must retain the current training record for each hazmat employee:
- while the individual is employed as a hazmat employee;
- and for 90 days afterward.
Because recurrent training is generally required every three years, the retained current training record includes the relevant preceding training cycle.
The record includes:
- employee name;
- most recent completion date;
- training materials;
- trainer name and address;
- certification of training and testing.
Shipping papers
Hazardous-material shipping papers are generally retained for two years.
For hazardous waste, the retention period is generally three years after the material is accepted by the initial carrier.
Special operations can have additional:
- registration;
- security-plan;
- incident-reporting;
- cargo-tank;
- package;
- emergency-response
retention duties.
Records that do not share one simple DOT period
Some business documents remain important even when they do not fit one universal FMCSA safety-retention period.
Examples include:
- insurance policies and endorsements;
- BMC filing confirmations;
- BOC-3 records;
- UCR receipts;
- IRP and IFTA records;
- Form 2290 and Schedule 1;
- bills of lading;
- broker contracts;
- freight invoices;
- cargo claims;
- payroll;
- tax returns.
These can be governed by:
- another federal agency;
- state law;
- tax law;
- contract;
- insurance policy;
- claim limitation;
- litigation need.
A DOT retention schedule should therefore be one section of a broader company records schedule.
How to build a retention schedule
A small carrier can manage retention in a spreadsheet or compliance system.
Create one row for each record category.
| Field | Purpose |
|---|---|
| Record category | Identifies the type of document |
| Regulatory citation | Shows the legal source |
| Trigger date | Determines when the period begins |
| Minimum period | States the regulatory floor |
| Calculated deletion date | Prevents early destruction |
| Legal hold | Blocks deletion when a claim or investigation exists |
| Storage location | Allows rapid retrieval |
| Record owner | Assigns responsibility |
| Deletion approval | Creates controlled destruction evidence |
How to organize compliance records
The carrier does not need a complicated filing system. The objective is to separate each type of record so that it can be found quickly during an audit, claim or roadside investigation.
| Record category | What belongs there |
|---|---|
| Company and registration | USDOT, operating authority, BOC-3, UCR and company records |
| Insurance | Policies, endorsements, certificates and federal filings |
| Drivers | Qualification files, MVRs, medical records and investigation history |
| Drug and alcohol | Testing-program, C/TPA and restricted testing records |
| Hours of service | ELD exports, paper logs, time records and supporting documents |
| Vehicles | Maintenance, annual inspections, repairs and vehicle identification |
| Roadside inspections | Inspection reports, repair evidence and returned certifications |
| Accidents | Accident register, reports, photographs and insurer correspondence |
| Hazardous materials | Training, shipping papers and hazmat-specific records |
| Legal holds | Records that must not be deleted because of a claim or investigation |
Use consistent file names
A practical format is:
Date + driver or vehicle + document type
Examples:
2026-08_DRIVER-JONES_ELD-EXPORT.csv2026-08_DRIVER-JONES_SUPPORTING-DOCUMENTS.pdf2026-09-04_UNIT-101_BRAKE-REPAIR.pdf2026-09-18_UNIT-101_ROADSIDE-INSPECTION.pdf2026-10-02_DRIVER-JONES_ANNUAL-MVR.pdf
The exact folder names are not regulated. What matters is that the records are secure, complete and easy to retrieve.
Legal holds and extended retention
A legal hold suspends ordinary deletion when records may be relevant to:
- accident;
- lawsuit;
- demand letter;
- insurer investigation;
- cargo claim;
- employment dispute;
- government investigation;
- audit;
- subpoena.
The hold should identify
- matter;
- affected drivers;
- affected vehicles;
- date range;
- record categories;
- person issuing the hold;
- release date.
Preserve vendor data immediately
When an event occurs, export data before normal deletion from:
- ELD;
- dash camera;
- telematics;
- email;
- dispatch system;
- mobile devices;
- maintenance portal.
A six-month regulatory minimum does not protect data already deleted by a vendor after 30 or 90 days.
Common retention mistakes
Mistake 1: Applying three years to every record
Some records require only months, while others require five years or employment plus three years.
Mistake 2: Calculating from the wrong date
Use the regulatory trigger, not the upload date.
Mistake 3: Letting a vendor delete required data
Export records before service limits expire.
Mistake 4: No separate ELD backup
The original cloud portal and required backup are different.
Mistake 5: Storing confidential testing records in an open folder
Use controlled access.
Mistake 6: Deleting driver files three years after hiring
The post-employment period generally begins after employment ends.
Mistake 7: Deleting accident records during a claim
Apply a legal hold.
Mistake 8: Keeping only summaries
Retain the underlying records and required data.
Mistake 9: No destruction log
Document what was deleted, when and under which schedule.
Mistake 10: Confusing federal minimums with state requirements
Check the operating and licensing states.

Implementation process
How to implement a DOT retention program
- 01 Inventory every record category
List driver, testing, HOS, vehicle, accident, hazmat and company records.
- 02 Assign the governing rule
Identify the federal citation and any state, tax or contractual requirement.
- 03 Define the trigger date
Use receipt, execution, inspection, accident, termination or control-end dates correctly.
- 04 Calculate the minimum deletion date
Use a system rather than relying on folder age.
- 05 Create controlled storage
Separate confidential files and maintain company-controlled backups.
- 06 Test record production
Confirm the company can retrieve and export requested records promptly.
- 07 Create a legal-hold process
Suspend deletion after accidents, claims, investigations and disputes.
- 08 Review before destruction
Require approval and confirm no longer period applies.
- 09 Document deletion
Maintain a destruction log without preserving the deleted confidential content.
