TL;DR — Key Takeaways
- 49 CFR 390.15 requires every motor carrier to maintain an accident register for qualifying crashes.
- A DOT-recordable accident involves a fatality, injury requiring immediate medical treatment away from the scene, or a disabled vehicle needing tow-away.
- Records must be retained for a minimum of three years from the accident date.
- Missing or incomplete accident registers can trigger penalties up to $1,584 per day for recordkeeping violations, capped at $15,846.
- Falsifying accident register entries carries a separate penalty of up to $15,846 per violation.
- Auditors cross-reference your accident register against FMCSA crash databases, insurance claims, and driver logs during a compliance review.
- A written accident register policy and a standardized intake form are the two fastest ways to close compliance gaps before an audit.
What Is the DOT Accident Register and Who Must Keep One?
The DOT accident register is a written log that every FMCSA-regulated motor carrier must maintain under 49 CFR 390.15. It applies to any carrier operating commercial motor vehicles (CMVs) in interstate commerce, regardless of fleet size — including owner-operators with a single truck. The register documents specific details about qualifying crashes so that FMCSA investigators and state auditors can assess a carrier's safety history and identify patterns.
There is no fleet-size exemption. If you hold operating authority or a USDOT number and operate CMVs, you are required to maintain this register. Intrastate carriers operating under state DOT authority should verify whether their state adopts the federal standard, but most do.
What Qualifies as a DOT-Recordable Accident Under 49 CFR 390.15?
A DOT-recordable accident under 49 CFR 390.15(b) is any accident involving a CMV on a public road that results in one or more of three triggering conditions: a fatality of any person, a bodily injury to any person who receives immediate medical treatment away from the scene, or disabling damage to any vehicle requiring tow-away from the scene.
| Triggering Condition | Example | Recordable? |
|---|---|---|
| Fatality — any person | Driver or pedestrian dies at or after the scene | Yes |
| Injury requiring immediate off-scene medical treatment | Passenger taken by ambulance to ER | Yes |
| Disabling damage — tow-away required | Truck cannot be driven; tow truck called | Yes |
| Minor fender-bender, vehicle driven away | Bumper scratch, no injuries, no tow | No |
| On-premises incident (private lot, not public road) | Backing into dock inside a private warehouse | No (federal; check state rules) |
Note: An accident does not have to involve another vehicle. A single-vehicle crash that kills or injures the driver and requires a tow qualifies. The definition is broader than many fleet managers assume.
What Exactly Must Be Recorded in the Accident Register?
For each qualifying accident, 49 CFR 390.15(b)(1) specifies the minimum data fields that must appear in the register. Omitting even one field creates an incomplete record that auditors will flag.
- Date of the accident
- City or town and state where the accident occurred (or closest city/town)
- Driver's name
- Number of injuries
- Number of fatalities
- Whether hazardous materials were released (yes or no)
In addition to these six mandatory fields, FMCSA strongly recommends — and auditors practically expect — that carriers also attach or reference copies of any accident reports, citations issued, insurance claim numbers, post-accident drug and alcohol test results, and driver statements. These supporting documents are not required by the minimum register rule but are routinely requested during compliance reviews and Compliance Safety Accountability (CSA) investigations.
How Long Must Small Trucking Fleets Keep DOT Accident Records?
Under 49 CFR 390.15(b)(2), the accident register and all accident-related documents must be retained for a minimum of three years from the date of each accident. There is no provision to purge records earlier, even if a claim is settled or the driver no longer works for the carrier.
| Record Type | Minimum Retention Period | CFR Citation |
|---|---|---|
| Accident register (the log itself) | 3 years from accident date | 49 CFR 390.15(b)(2) |
| Driver qualification files | 3 years after driver leaves | 49 CFR 391.51 |
| Hours of service records (paper/ELD) | 6 months | 49 CFR 395.8(k) |
| Drug & alcohol test results (positive) | 5 years | 49 CFR 382.401 |
| Post-accident drug/alcohol test records | 5 years (positive); 1 year (negative) | 49 CFR 382.401 |
Store records in a format that is legible, organized, and retrievable within the timeframe auditors specify — typically within 48 hours of a request during a roadside investigation, or at the start of a comprehensive review.
What Is New in 2026 for DOT Accident Register Compliance?
The core rule under 49 CFR 390.15 has not changed for 2026, but three developments make compliance more urgent for small fleets this year.
- Increased civil penalty inflation adjustments: FMCSA adjusts civil penalties annually for inflation under the Federal Civil Penalties Inflation Adjustment Act. For 2026, general recordkeeping violations carry penalties up to $1,584 per day, with a maximum of $15,846. Falsification of records carries up to $15,846. Operating after an out-of-service order rises to $23,048.
- Enhanced CSA data matching: FMCSA's expanded crash data integration means auditors now cross-reference state police crash reports automatically against carrier accident registers. Gaps are flagged before an investigator even contacts you.
- SMS Prioritization for small fleets: FMCSA's Safety Measurement System (SMS) now surfaces small carriers with fewer than 10 power units for targeted interventions when their Crash Indicator BASIC score exceeds the threshold. Incomplete registers directly inflate that score.
What Do FMCSA Auditors Actually Look For in Your Accident Register?
During a compliance review, auditors pull your accident register first and compare it against independent data sources. Discrepancies — not just missing records — are the most common audit failure point for small fleets.
- Completeness check: All six mandatory fields populated for every entry.
- Crash database cross-reference: Auditors compare your register against MCMIS (Motor Carrier Management Information System) crash data and state DOT reports. An accident in MCMIS that is absent from your register is an immediate violation.
- Post-accident testing linkage: They verify that qualifying accidents triggered the required post-accident drug and alcohol testing under 49 CFR 382.303 and that test records are on file.
- Supporting document availability: Police reports, insurance claims, and driver statements should be attached or cross-referenced by file number.
- Timeliness of entry: While the rule does not specify a maximum time to enter an accident, auditors look for patterns suggesting retroactive entry or reconstruction, which can escalate to a falsification finding.
Small fleet owners managing HR and compliance manually are disproportionately exposed to these gaps. Purpose-built tools built for trucking HR — like those offered at HRForge's trucking HR platform — allow carriers to log incidents, attach documents, and trigger automated post-accident checklists the moment an event is reported.

What Happens If You Fail to Maintain a Proper Accident Register?
Non-compliance with 49 CFR 390.15 is not a technical footnote — it carries direct financial and operational consequences. Auditors can issue violations that directly affect your CSA score, your safety rating, and your ability to operate.
- Civil penalties: Recordkeeping violations up to $1,584 per day, maximum $15,846 per violation.
- Falsification: Up to $15,846 per falsified entry — this can apply if an auditor determines records were reconstructed after the fact without basis.
- Conditional or unsatisfactory safety rating: Patterns of incomplete records contribute to a conditional or unsatisfactory safety rating, which can cause shippers, brokers, and insurers to drop you.
- Increased scrutiny: One failed audit often triggers follow-up compliance reviews within 12 months.
For small fleets operating on thin margins, a single compliance review resulting in a conditional safety rating can cost far more than the penalty itself through lost freight contracts and insurance premium increases. Proactive recordkeeping is the lowest-cost risk mitigation available. HRForge helps small trucking fleets automate DOT recordkeeping, including accident register management, so nothing falls through the cracks between dispatch and dispatch.
Frequently Asked Questions
Does the DOT accident register requirement apply to fleets with fewer than five trucks?
Yes. 49 CFR 390.15 applies to all FMCSA-regulated motor carriers regardless of fleet size. There is no small-fleet exemption. Owner-operators with a single CMV who hold operating authority must maintain a compliant accident register. The only vehicles potentially excluded are those that never meet the CMV definition under 49 CFR 390.5, such as vehicles under 10,001 lbs not transporting HazMat or passengers for hire.
What is the difference between a DOT-recordable accident and an OSHA-recordable incident?
A DOT-recordable accident under 49 CFR 390.15 applies to CMV crashes on public roads and focuses on fatalities, off-scene injuries, and tow-aways. An OSHA-recordable incident under 29 CFR 1904 covers workplace injuries and illnesses regardless of vehicle involvement, with different thresholds such as days away from work, restricted duty, or medical treatment beyond first aid. Many trucking accidents trigger both obligations, and carriers must maintain separate records for each.
Can I keep the accident register electronically?
Yes. FMCSA does not mandate paper records for the accident register. Electronic records are acceptable as long as they are secure, tamper-evident, contain all required fields, and can be produced in a readable format within the timeframe an investigator requests — generally within 48 hours for a roadside investigation or immediately upon arrival for a comprehensive review. Back up electronic records regularly and ensure they are not editable without an audit trail.
What triggers the post-accident drug and alcohol testing requirement?
Under 49 CFR 382.303, post-accident drug testing is required when a driver receives a citation following an accident involving a fatality, or when a citation is issued and there was a bodily injury with immediate off-scene medical treatment, or a vehicle required tow-away. Alcohol testing must occur within 8 hours of the accident; drug testing within 32 hours. If testing is not completed within those windows, the reason must be documented.
How do auditors find accidents that are not in my register?
FMCSA auditors cross-reference your accident register against the Motor Carrier Management Information System (MCMIS), which is populated by state police crash reports, roadside inspection data, and insurance reporting. If a crash appears in MCMIS but not in your register, auditors treat it as a missing required record — potentially a falsification issue if they believe the omission was intentional. This is the most common source of accident register violations for small fleets.
Does a crash in a private parking lot count as a DOT-recordable accident?
Generally no under 49 CFR 390.15, because the federal definition requires the accident to occur on a public road or highway. However, state DOT regulations and insurance requirements may treat private-property accidents differently. Some states that have adopted federal regulations with modifications may apply broader definitions. Always check your state's specific CMV regulations and consult your insurance carrier, as a private-lot crash may still trigger workers' compensation and OSHA recordkeeping obligations.
