If you run under your own authority, FMCSA Accident Register Requirements matter anytime a crash may cross the federal recordkeeping line. The big point: this is usually a keep-it-on-file rule, not a submit-every-crash-to-FMCSA rule. Knowing the difference helps owner-operators and small fleets avoid bad assumptions after an accident.
FMCSA Accident Register Requirements: Quick Answers#
FMCSA requires motor carriers to keep an accident register for qualifying crashes under 49 CFR 390.15. A motor carrier is the business responsible for operating the truck, even if it’s a one-truck owner-operator. This is a recordkeeping duty, not a routine form you automatically send to FMCSA after every accident.
Who needs an accident register#
If you’re operating as a motor carrier and a qualifying crash happens, you need an accident register entry. The rule applies to accidents involving a commercial motor vehicle (CMV), which is a vehicle used in commerce that meets the federal definition in 49 CFR Part 390.
The three-part DOT-recordable accident test#
A crash belongs in the register if a CMV was operating on a highway and the accident caused at least one of three outcomes: a fatality, immediate medical treatment away from the scene, or disabling damage requiring a vehicle to be transported away. Don’t use fault, how bad it looked, or whether insurance paid the claim as your test.
The three-year retention rule#
The accident register must be kept for three years after the date of each accident. That means you should be able to pull the entry and the required related reports during that retention period.
What Qualifies as a DOT-Recordable Accident?#
A DOT-recordable accident under 49 CFR 390.5 is a crash involving a CMV on a highway that results in a fatality, immediate medical treatment away from the scene, or disabling damage requiring a vehicle to be transported away. The rule is about the facts of the event, not who caused it.
Under the definition in 49 CFR Part 390 on eCFR, start with the vehicle and location. A CMV must be involved, and the crash must happen on a highway. If it’s not a CMV event on a highway, it doesn’t meet this federal accident-register definition.
A commercial motor vehicle must be involved#
A CMV is defined in the federal safety regulations, and whether your truck fits that definition matters before you even get to injuries or damage. For most owner-operators, that threshold is easy because the truck is plainly operating in commerce.
The crash must occur on a highway#
The highway piece matters because not every yard incident, private-lot scrape, or shop mishap falls into the same bucket. You may still need to document those events internally, but they aren’t automatically FMCSA accident-register entries.
Fatality, off-scene medical treatment, or disabling damage#
A fatality counts regardless of fault. If a person dies as a result of the crash, the accident qualifies.
An injury counts when it requires immediate medical treatment away from the scene. On-scene first aid by itself does not meet that part of the definition.
Disabling damage means damage that keeps a vehicle from leaving under its own power in its usual manner and requires transport away from the scene. Towing or other transport away is a strong signal here. Minor cosmetic damage, a bumper scrape, or a drivable vehicle by itself usually does not meet the disabling-damage threshold.
This is where drivers get tripped up. A claim can be expensive and still not be a DOT-recordable accident, while a no-fault crash can still belong in the register.
If you’re sorting through a close call and don’t want to guess wrong,
What Must an FMCSA Accident Register Include?#
An FMCSA accident register must include the accident date, the city or town nearest the scene, the driver’s name, the number of injuries, the number of fatalities, and whether hazardous materials other than fuel from the vehicle’s own tank were released. The carrier must also keep copies of required accident reports from government entities or insurers.
Under 49 CFR Part 390 on eCFR, those required fields are the core of the register. Don’t replace them with a stack of photos or an insurance claim number and assume you’re covered.
Required details for every qualifying accident#
For each qualifying crash, capture these details in one consistent register:
- Accident date
- City or town nearest the accident scene
- Driver name
- Number of injuries
- Number of fatalities
- Whether hazardous materials, other than fuel from the vehicle fuel tank, were released
State and local accident reports#
The carrier must also maintain copies of all accident reports required by state or other governmental entities or insurers. That means your register entry is only part of the file. If a state crash report exists, or your insurer requires accident documentation, keep those records tied to the same event.
Documents worth preserving beyond the register#
Supporting documents aren’t the same thing as the required register entry, but they’re still worth preserving. Common examples include driver statements, scene photos, dispatch messages, vehicle inspection information, maintenance records, insurance claim documents, and repair invoices.
Those records help with claims, litigation, safety reviews, and internal investigation. They do not replace the required fields under 49 CFR 390.15.
A practical setup is one controlled location for every accident file, whether that’s a spreadsheet, PDF log, or fleet-management system. Use a simple naming format so you can find the file fast later, especially if FMCSA, an insurer, or an attorney asks for records months after the crash.
| Record item | Required by 49 CFR 390.15 | Why it matters |
|---|---|---|
| Accident date | Yes | Core register field |
| Nearest city or town | Yes | Core register field |
| Driver name | Yes | Core register field |
| Number of injuries | Yes | Core register field |
| Number of fatalities | Yes | Core register field |
| Hazmat release status | Yes | Core register field |
| State crash report copy | Yes, if required | Supports compliance file |
| Insurer accident report | Yes, if required | Supports claim handling |
| Photos, statements, repairs | No, but useful | Supports claims and review |
Does a Motor Carrier Have to Report Every Accident to FMCSA?#
No, a motor carrier does not routinely submit every qualifying accident directly to FMCSA just because it belongs in the accident register. Under 49 CFR 390.15, the basic federal duty is to maintain the register and keep required reports on file.
This is where people mix up recordkeeping with reporting. Keeping an accident register is one compliance duty. Submitting notices to law enforcement, state agencies, insurers, or hazmat authorities can be separate duties with different triggers.
Keeping a register versus submitting a report#
A register entry stays in your records unless some other rule or investigation requires production. It is not the same thing as logging into an FMCSA portal and filing every crash there.
Separate reporting and notification duties#
An accident can still trigger other obligations, including state crash-report rules, insurer notice, hazardous-materials incident reporting, and post-accident testing questions. Those duties do not all use the same definition or timing.
Why insurance and state reporting still matter#
Your crash can also show up in safety-related systems used for oversight and carrier research, but that doesn’t make the register test and the safety-data question interchangeable. You can verify carrier-related safety information through FMCSA’s SAFER system, but your own duty under 49 CFR 390.15 is still to maintain accurate records.
Check the state where the crash happened, your cargo, and your operating setup before assuming there’s one universal DOT reporting path.
How Long Must Company Accident Registers Be Kept?#
Motor carriers must keep accident-register records for three years after the date of each accident. The retention clock runs from the accident date, not from the date the claim closes or the truck returns to service.
During that three-year period, you should be able to retrieve the required register entry and the required related accident reports without digging through old phones, glove boxes, or text threads. For a one-truck operation, that usually means one clean digital folder plus a backed-up master log.
The three-year FMCSA retention period#
The federal rule is straightforward on the register itself: keep it for three years after each accident date. If you have multiple accidents, each entry follows its own timeline.
When the retention clock starts#
Start counting from the actual date of the accident. Don’t wait until repairs finish, the insurer pays, or the lawsuit risk feels lower.
Why related records may have different retention periods#
Other records may follow different retention rules. That can include drug-and-alcohol testing records, maintenance records, insurance files, state-required reports, or litigation holds. Don’t set one blanket purge date for every crash-related document without checking what rule applies to that category.
How to Handle a Qualifying Accident: A Practical Owner-Operator Workflow#
After a qualifying accident, handle people and safety first, then build the compliance file while the facts are still fresh. A good workflow helps you separate the required FMCSA register entry from insurance, state, hazmat, and testing steps that may follow.
At the scene: protect people and preserve basic facts#
Get emergency help if needed, follow law-enforcement instructions, notify dispatch or the carrier if that applies to your setup, and notify your insurer according to the policy. Then capture the facts you’ll need later: date, nearest city or town, driver name, injuries, fatalities, towing or disabling damage, and any hazardous-material release.
If you can do it safely, preserve photos, witness information, vehicle positions, and visible damage. Don’t overwrite originals or edit key files in ways that make later review harder.
Within the first business day: determine whether the register applies#
Once the immediate situation is under control, ask the register question using the federal test. Was a CMV involved on a highway, and did the event involve a fatality, immediate medical treatment away from the scene, or disabling damage requiring transport away?
If yes, create the register entry and request or obtain required state or local accident reports when they become available. Build one incident file and keep the register field data easy to find.
After the file is created: track follow-up obligations#
Now check the other rule sets that may apply. Post-accident drug and alcohol testing is testing required after certain crashes under separate federal rules, not automatically after every registerable accident. Under 49 CFR Part 382 on eCFR, especially 49 CFR 382.303, testing uses its own accident and citation triggers.
If cargo or a release is involved, review applicable hazmat procedures too. Not every spill follows the same reporting path under the Hazardous Materials Regulations.
If you’re not sure which records matter for compliance versus claims,
What Does Not Belong in the FMCSA Accident Register?#
Not every roadside event, property-damage claim, or safety issue belongs in the FMCSA accident register. If the federal definition in 49 CFR Part 390 isn’t met, the incident may still matter, but not as a 390.15 register entry.
Minor property damage with no disabling damage#
A minor scrape where both vehicles stay operable and leave under their own power usually does not meet the disabling-damage part of the rule. Expensive cosmetic damage alone is not the test.
On-scene first aid without qualifying medical treatment#
If the only injury response is on-scene first aid, that alone does not meet the off-scene medical-treatment trigger. What matters is immediate medical treatment away from the accident scene.
Internal safety incidents that still deserve documentation#
Near misses, load-shift concerns, yard bumps, or customer-property incidents may still need an insurer report, customer notice, maintenance follow-up, or an internal company record. If you’re on the fence, document the uncertainty and verify it. Don’t leave an event out just because a driver’s first impression was, “It wasn’t that serious.”
Accident Register FAQ#
What are the requirements for reporting an accident to FMCSA?#
For most carriers, 49 CFR 390.15 requires keeping an accident register for qualifying crashes rather than routinely submitting every accident to FMCSA. A qualifying event is a CMV accident on a highway involving a fatality, immediate medical treatment away from the scene, or disabling damage requiring transport away. Separate duties may still apply, including state crash reporting, insurer notice, hazmat incident reporting, and post-accident testing review. Treat those as separate compliance questions, not automatic extensions of the register rule.
What is a DOT accident register?#
A DOT accident register is a motor carrier’s required record of qualifying CMV accidents under 49 CFR 390.15. It includes the accident date, nearest city or town, driver name, number of injuries, number of fatalities, and whether hazardous materials other than fuel from the vehicle’s own tank were released. The carrier must also keep copies of applicable accident reports required by government entities or insurers. Think of it as a controlled compliance log, not just a loose pile of claim paperwork.
How long are company accident registers kept on file?#
Company accident registers must be kept for three years after the date of each accident. That means each qualifying crash entry has its own three-year retention timeline. During that period, the carrier should be able to retrieve the register entry and the required related reports. Keep in mind that supporting records may have longer or different retention requirements depending on the document type, including drug-and-alcohol testing records, maintenance files, insurance files, state rules, or pending litigation.
What qualifies as a DOT recordable accident?#
A DOT-recordable accident uses a three-part test from 49 CFR 390.5. First, a commercial motor vehicle must be involved. Second, the crash must occur on a highway. Third, it must result in at least one of these outcomes: a fatality, immediate medical treatment away from the scene, or disabling damage requiring a vehicle to be transported away. Fault does not control the answer, and neither does your assumption about how serious the crash felt at the time.
Do non-DOT incidents still need to be documented?#
Yes, many non-DOT incidents still deserve documentation even if they do not belong in the FMCSA accident register. A minor scrape, yard impact, customer-property event, or maintenance-related roadside issue may still matter for insurance, company safety review, repair tracking, or state requirements. The smart move is to keep organized records alongside your insurance and claim documentation, then verify any close-call compliance questions before you purge or ignore the file.
