A complete walkthrough of the FMCSA accident register requirement under 49 CFR 390.15 — what counts as a reportable accident, exactly what has to be recorded, why auditors ask for it first, and the up-to-$15,846 penalty for not having one, even with a spotless safety record.
- Under 49 CFR 390.15(b), every motor carrier must maintain an accident register listing every DOT-reportable crash for the preceding three years, and keep it available for inspection.
- “Reportable” has a specific federal definition (49 CFR 390.5): a fatality, an injury requiring immediate medical treatment away from the scene, or disabling damage requiring a vehicle to be towed from the scene.
- The register must contain, at minimum: the date of the crash, the city or town and state nearest to where it occurred, the driver’s name, the number of injuries, the number of fatalities, and whether hazardous materials (other than fuel spilled from the vehicle’s own tank) were released — plus copies of any accident reports filed with a state, another government entity, or the carrier’s insurer.
- FMCSA does not prescribe a specific form. A spreadsheet, a binder, or a one-page template all satisfy the rule, as long as it contains the required elements and covers the full three-year window.
- Failing to prepare or maintain a record required under Parts 390 through 399 — which includes the accident register — carries a civil penalty of up to $1,584 for each day the violation continues, capped at $15,846, under FMCSA’s 2025 penalty schedule (49 CFR Part 386, Appendix B). Knowingly falsifying or destroying a required record carries its own separate maximum penalty of $15,846.
- FMCSA’s own Motor Carrier Safety Planner lists accident recordkeeping under 390.15 as a specific item examined during compliance reviews and new entrant safety audits.
A compliance review starts the same way almost every time: the auditor asks for the accident register before asking for anything else. Not the maintenance files, not the driver qualification files — the accident register. A two- or three-truck fleet that has never had a reportable crash assumes there’s nothing to produce. That assumption is wrong, and it is the single easiest finding an auditor writes up.
The accident register isn’t a crash log a fleet builds after something happens. It’s a standing federal recordkeeping requirement that exists whether or not the fleet has ever had a reportable accident — and a fleet with zero qualifying crashes still has to be able to show the register itself, even if the entries are empty.
What counts as “reportable,” and why that definition matters first
Before a fleet can build an accurate accident register, it has to know what belongs in it. 49 CFR 390.5 defines a reportable accident as an occurrence involving a commercial motor vehicle on a public road that results in at least one of three things: a fatality; a bodily injury to a person who immediately receives medical treatment away from the scene; or disabling damage to a vehicle that requires it to be towed from the scene.
That’s a narrower test than “anything involving a truck.” A cracked mirror or a parking-lot scrape that gets fixed on the spot doesn’t meet the federal definition and doesn’t have to go in the register. But a crash that sends someone to urgent care two blocks away, even with no police report and no lawsuit, does meet it — and a fleet that only logs the crashes that “felt serious” at the time is the fleet that shows up to an audit with a register missing entries it didn’t know qualified.
What the register actually has to contain
Once a crash meets the federal definition, 49 CFR 390.15(b) is specific about what has to be recorded: the date of the accident; the city or town nearest to where it happened, and the state; the driver’s name; the number of injuries; the number of fatalities; and whether hazardous materials — other than fuel spilled from the vehicle’s own tank — were released. The carrier also has to keep copies of any accident reports it filed with a state or other government entity, or with its insurer, for that crash.
There’s no FMCSA-issued form to fill out. A carrier can build the register as a spreadsheet, a binder, or a single typed page, as long as every required field is there and the register covers the full three years counting back from today. The format is flexible. The three-year completeness is not.
Why this is an auditor’s first question, not an afterthought
FMCSA’s own Motor Carrier Safety Planner — the reference material auditors themselves use — lists accident recordkeeping under 390.15 as a distinct item examined during compliance reviews and new entrant safety audits. It sits alongside driver qualification files and drug and alcohol testing records as one of the standard document requests, not a rarely-cited technicality.
That’s the part small fleets consistently misjudge. A fleet with a clean safety record for three years reasonably assumes the accident register is irrelevant to them. It isn’t. The requirement to maintain the register exists independent of whether the fleet has had a single reportable crash — a fleet with zero qualifying accidents in the window still needs to be able to produce the register showing that, in the format the rule requires, not just assert it verbally to an auditor.
The cost of not having one
Recordkeeping violations under Parts 390 through 399 — the range that includes 390.15 — carry a civil penalty of up to $1,584 for each day the violation continues, capped at $15,846 per violation, under FMCSA’s 2025 penalty schedule at 49 CFR Part 386, Appendix B. A separate provision in the same appendix sets a maximum penalty of $15,846 for knowingly falsifying, destroying, mutilating, or altering a required record — a much more serious finding than simply not having built the register yet.
For a two- or three-truck operation, a finding like this doesn’t just cost the civil penalty. It becomes part of the carrier’s compliance history on file with FMCSA, and it’s the kind of finding that turns a routine audit into a longer one, because an auditor who finds one missing required record starts looking harder at the rest of the file.
What most small fleets get wrong
The first mistake is assuming “no accidents” means “nothing to produce.” The register itself is the required record — an empty register, properly maintained and dated, is the correct answer for a clean safety history. A fleet with no register at all, even with a spotless driving record, still has a recordkeeping gap.
The second mistake is logging incidents by gut feeling instead of the federal definition in 49 CFR 390.5. A crash that didn’t result in a tow, an injury requiring off-scene treatment, or a fatality doesn’t have to be in the register — but a fleet that has never checked the definition against its own incident history can’t confidently say which of its past events do or don’t qualify.
The third mistake is treating this as paperwork that can be reconstructed after the fact. The register has to cover three years on a rolling basis. A fleet that starts one the week before an audit is scrambling for two-plus years of records it may not be able to fully rebuild from memory, insurance claims, and old dispatch notes.
As the Responsible Fleet team has told small operators reviewing their files ahead of an audit: the accident register is one of the cheapest compliance items to get right, because it doesn’t require training, equipment, or a policy change — it requires a spreadsheet that someone actually keeps current.
Frequently asked questions
Does a fleet with zero accidents in the past three years still need an accident register?
Yes. The requirement under 49 CFR 390.15(b) is to maintain the register itself, not just to log crashes when they happen. A properly dated register showing no reportable accidents is the correct document to produce for a clean safety history — having no register at all is still a recordkeeping violation.
What crashes actually have to go in the register?
Only those meeting the federal definition of a reportable accident under 49 CFR 390.5: a fatality, an injury requiring immediate medical treatment away from the scene, or disabling damage requiring the vehicle to be towed from the scene. Minor incidents that don’t meet one of those three conditions don’t have to be listed.
What information does the register have to include for each qualifying crash?
Under 49 CFR 390.15(b), the date, the nearest city or town and state, the driver’s name, the number of injuries, the number of fatalities, and whether hazardous materials other than the vehicle’s own fuel were released — plus copies of any accident reports filed with a state, another government entity, or the carrier’s insurer.
Is there an official FMCSA form for the accident register?
No. FMCSA does not prescribe a specific form. A spreadsheet, binder, or template is acceptable as long as it includes every required element and covers the full three-year window.
What’s the penalty for not maintaining one?
Recordkeeping violations covering Parts 390 through 399, which includes 390.15, carry a civil penalty of up to $1,584 per day the violation continues, capped at $15,846, under FMCSA’s 2025 penalty schedule (49 CFR Part 386, Appendix B). Knowingly falsifying a required record carries a separate maximum penalty of $15,846.
The bottom line
The accident register is one of the shortest sections in the Federal Motor Carrier Safety Regulations, and one of the most consistently missing documents in small-fleet files — usually not because an operator is ignoring the rule, but because a clean safety record makes the requirement feel irrelevant. It isn’t. The register itself is what the rule requires, and producing it is the difference between a five-minute audit item and a finding that gets written up.
As the Responsible Fleet team puts it: the fleets that get flagged for this one aren’t the ones with a bad safety record. They’re the ones with a good safety record and no piece of paper to prove it.
