How Long Do You Have to Keep DOT Records? (Retention Periods Explained)

There is no single answer to how long to keep DOT records — every record type runs on its own clock, and the only safe rule is keep longer, never shorter, because shredding a file a month too early is just as damaging in an audit as never having had it. A small carrier that tosses a driver’s qualification file the day they quit, or purges last quarter’s logs to clear space, has quietly created a gap — and to a DOT investigator, a gap reads as non-compliance, not as good housekeeping. This guide lays out the DOT record retention requirements by record type, the CFR part behind each one, and how to keep every clock running without thinking about it.

General information, not legal advice — always verify retention periods directly with FMCSA. Rules change, and your operation (interstate vs. intrastate, cargo, vehicle weight) can change what applies to you. When in doubt, keep the record.

DOT record retention periods at a glance

Here are the commonly-cited retention periods most small carriers work from. Treat these as the baseline, verify the specifics against the regulation, and when a record sits near the edge of its window, hold onto it.

Record type	Governing rule	Commonly-cited retention
Driver Qualification File (DQF)	49 CFR Part 391	Duration of employment + 3 years after separation
Drug & alcohol — positives, refusals, return-to-duty	49 CFR Part 382	Generally up to 5 years
Drug & alcohol — negative results	49 CFR Part 382	Generally about 1 year
Hours-of-Service records (RODS) + supporting docs	49 CFR Part 395	6 months
Driver Vehicle Inspection Reports (DVIRs)	49 CFR Part 396	About 3 months
Vehicle maintenance / inspection records	49 CFR Part 396	Generally while the vehicle is controlled + ~6 months after
IFTA records	IFTA Articles of Agreement	4 years
IRP records	IRP / base jurisdiction	Typically per your base jurisdiction (commonly multi-year)
Accident register	49 CFR 390.15	3 years

The rest of this guide walks each one in plain language.

Driver Qualification File: employment + 3 years

The DQF is the most-examined record in any audit, and its retention rule trips people up because it isn’t a fixed number of years — it’s tied to the driver. Under 49 CFR Part 391, you generally keep the qualification file for the entire duration of the driver’s employment, plus 3 years after they separate. That means the day a driver quits, the clock doesn’t stop — it starts a fresh three-year countdown.

A few items inside the file run on their own sub-cycle while the driver is active: the MVR and the annual review of driving record are generally kept for 3 years on a rolling basis, and you retain the most recent medical examiner’s certificate. But the headline rule for the file as a whole is duration of employment + 3 years. This is exactly where early shredding happens — a driver leaves, the folder looks “done,” and it gets cleared out months later. If an audit lands inside that three-year tail, the missing file is a finding. For the full document-by-document breakdown, see our Driver Qualification File checklist.

Drug & alcohol testing records: up to 5 years (or ~1 year)

Drug and alcohol records under 49 CFR Part 382 don’t have one retention period — they split by result. Generally:

• Positives, refusals, and return-to-duty / follow-up testing records are kept for up to 5 years. These are the records that document a violation and the driver’s path back to safety-sensitive duty, so the regulation holds them the longest.
• Negative results are generally kept for about 1 year.

Because the longer five-year clock attaches to the most consequential records, this is one where carriers most often under-retain. When you’re unsure which bucket a record falls in, default to the longer period. Clearinghouse query records (pre-employment and annual) are tracked separately and generally kept for 3 years — covered in our DQF checklist.

Hours-of-Service records (RODS): 6 months

Records of duty status and the documents that support them are kept for 6 months under 49 CFR Part 395. That includes the driver’s logs (whether from an ELD or paper, where paper is still permitted) and the supporting documents — bills of lading, dispatch records, fuel receipts, and similar paperwork that an investigator uses to verify the logs are accurate.

Six months feels short next to the multi-year files, which is exactly why it gets neglected: it’s easy to assume logs are “old news” and let them roll off, but a roadside inspection or a focused HOS audit can ask for any day inside that window. Keep the supporting documents together with the logs they back up — half a record is hard to defend.

DVIRs and maintenance records: ~3 months and beyond

Two related-but-different clocks live under 49 CFR Part 396:

• Driver Vehicle Inspection Reports (DVIRs) — the daily/post-trip inspection reports — are generally kept for about 3 months.
• Vehicle maintenance and inspection records are generally kept for as long as the vehicle is under your control, plus about 6 months after it leaves your fleet. This covers your maintenance history, the annual periodic (DOT) inspection records, and repair documentation.

The maintenance-record rule is the one that surprises owner-operators: selling or returning a truck doesn’t let you immediately discard its file. You generally carry those records roughly six months past the point you stop controlling the vehicle.

IFTA and IRP records: 4 years (and base-jurisdiction rules)

Fuel-tax and apportioned-plate records run on their own, longer cycles that have nothing to do with the FMCSA safety regulations:

• IFTA records — the mileage and fuel documentation behind your quarterly fuel-tax returns — are generally kept for 4 years from the return due date or filing date. This is one of the longest common retention windows a small carrier deals with, and an IFTA audit can reach back across all four years.
• IRP records are typically retained according to your base jurisdiction’s requirements (commonly a multi-year period covering the records that support your apportioned registration). Because IRP is administered through your base state, confirm the exact period with that jurisdiction.

Accident register: 3 years

Under 49 CFR 390.15, you maintain an accident register and keep it — along with the supporting accident reports and documentation — for 3 years after the date of each accident. Even a carrier with a clean record needs the register itself; “we’ve had no accidents” is something you should be able to show, not just say.

Why early shredding is a trap

Notice the pattern: almost every rule above is “keep for X” or “duration plus X” — never “you may discard immediately.” That design is deliberate. A DOT audit, a new-entrant safety audit, or a focused investigation can ask for any record that falls inside its retention window, and the window often extends well past the day a driver leaves or a truck is sold.

The failure mode is rarely a bad operator. It’s a good operator who cleans up too aggressively: the folder looked finished, the quarter looked closed, the truck was gone. But to an investigator, a missing record inside the window doesn’t read as tidy — it reads as non-compliant, and it can convert a routine review into citations. The asymmetry is the whole point: keeping a record a year too long costs you nothing; shredding it a month too early can cost you the audit. When a date sits near the edge, keep longer, never shorter. For more on where carriers get tangled, see the most confusing parts of FMCSA compliance.

Make retention automatic instead of a memory game

The reason records get tossed too early — or lost entirely — is almost never the rule itself. It’s the storage. Records scattered across a shoebox, a filing cabinet, three email threads, and a spreadsheet have no retention clock attached to them. Nobody knows which file is still inside its window and which one is safe to clear, so things get purged by guess — or never get found again when an investigator asks.

That’s the problem Fleetive is built to remove. Our document management keeps every record — DQF documents, drug-and-alcohol results, logs and supporting docs, DVIRs and maintenance history, IFTA paperwork, accident reports — organized and tied to the specific driver or unit it belongs to, in structured, audit-ready folders. Nothing lives in a shoebox or a stale spreadsheet, so nothing gets purged early by accident, and an audit becomes an export instead of a scramble.

On top of storage, our compliance & safety tools watch the active credentials that drive your retention obligations — CDLs, medical cards, MVR reviews, annual inspections — and flag them before they lapse, so a current document never quietly becomes a missing one. Storage that keeps records and tracking that watches the dates is the combination that turns retention from a thing you have to remember into a thing the system handles. It’s the same backbone behind our DOT audit preparation use case and the full DOT compliance guide.

Frequently asked questions

How long do I keep a driver qualification file? Generally for the duration of the driver’s employment plus 3 years after they separate, under 49 CFR Part 391. The three-year tail starts when the driver leaves — so don’t discard the file just because someone is no longer with you. Some items inside the file (the MVR and annual review) run on their own rolling 3-year cycle while the driver is active. Verify specifics with FMCSA.

How long to keep drug and alcohol test records? It depends on the result. Records of positives, refusals, and return-to-duty / follow-up testing are generally kept up to 5 years, while negative results are generally kept about 1 year, under 49 CFR Part 382. When you’re unsure which applies, keep the record for the longer period.

How long to keep IFTA records? Generally 4 years from the tax-return due date or filing date, per the IFTA agreement. It’s one of the longest common windows a small carrier maintains, and an IFTA audit can reach back across the full four years. IRP records are typically kept per your base jurisdiction’s rules — confirm the exact period with your base state.

How long to keep DVIRs and maintenance records? DVIRs (driver vehicle inspection reports) are generally kept for about 3 months. Vehicle maintenance and inspection records are generally kept while the vehicle is under your control plus about 6 months after it leaves your fleet, under 49 CFR Part 396 — so selling a truck doesn’t let you discard its file right away.

How long do I keep Hours-of-Service logs? Records of duty status (RODS) and their supporting documents — bills of lading, dispatch and fuel records — are generally kept for 6 months under 49 CFR Part 395. Keep the supporting paperwork together with the logs it backs up.

How long do I keep an accident register? Generally 3 years from the date of each accident, including supporting accident reports, under 49 CFR 390.15. Maintain the register even if you’ve had no accidents.

Can I keep DOT records digitally? Yes. DOT records can generally be maintained electronically as long as they’re complete, legible, and producible on request during an audit or inspection. Digital storage is actually easier to keep compliant, because the right system attaches each record to the driver or unit it belongs to and keeps it audit-ready — which is exactly what Fleetive’s document management does. Verify any format-specific requirements with FMCSA.

Keep every clock running — automatically

The retention rules don’t change much; what changes is whether anything is keeping track of which record is still inside its window. Stored in a shoebox or a spreadsheet, files get purged too early or lost entirely — and a gap inside the window reads as non-compliance. Stored in a system, every record stays organized, tied to its driver or unit, and audit-ready, while the active credentials behind those records get watched so nothing lapses unnoticed.
