How Long to Keep BOLs and Rate Cons (FMCSA Recordkeeping Rules)

Most small fleets either keep everything forever in a shoebox or delete things the moment a load is paid — both are the wrong instinct. The actual federal minimum, set by 49 CFR Part 379, is more specific and shorter than most owner-operators assume for day-to-day shipping paperwork. Here’s what the rule actually says, and why the smart number is usually longer than the legal minimum.

The FMCSA minimum for BOLs and freight bills: one year

Under Appendix A to 49 CFR Part 379 (the “Schedule of Records and Periods of Retention”), bills of lading, shipper’s instructions, waybills, freight bills, and other core day-to-day shipping documents fall under “Purchases and Stores Records” — and the federal minimum retention period there is just one year. That surprises a lot of fleets who assume it’s three, and it’s worth knowing precisely because the real-world reasons to keep records longer have nothing to do with this specific rule.

Other retention periods that apply to trucking records

The one-year rule is the floor for basic shipping paperwork, not the whole picture. A few other retention periods under the same Part 379 schedule and related FMCSA regulations apply depending on the record:

Hours-of-service supporting documents(fuel receipts, toll receipts, scale tickets, and anything else used to verify on-duty/not-driving time) — six months, under 49 CFR §395.11.

Weight ticketsand related records — three years.

Import/export records, including bonded freight and diversion or reconsignment records — two years.

Insurance and claims recordstied to a specific freight loss, damage, or injury claim — three years, longer than the general one-year insurance record rule.

If you work with a broker, know that the broker themselves is required to keep their own transaction records — including the rate confirmation and details of the brokered transaction — for three years under 49 CFR §371.3. That’s useful context in a dispute: even if your own copy has aged past the one-year minimum, the broker’s copy usually hasn’t.

Why the smart number is longer than the legal minimum

The one-year FMCSA floor for BOLs and freight bills is a compliance minimum, not a business recommendation. Two practical reasons push most fleets toward keeping records for at least three years: the IRS generally expects supporting documentation for at least three years from when a return was filed, and contract disputes — a broker disputing a rate, a shipper disputing a shortage — typically fall under state statutes of limitations that run considerably longer than one year, commonly four to six years for a written contract depending on the state. A record that legally satisfies FMCSA but is already gone when a broker disputes a charge eight months later, or an accountant asks for it during a 18-month-old return, doesn’t actually protect you.

What an audit or compliance review actually asks for

A DOT compliance review or new-entrant audit typically pulls hours-of-service records and supporting documents first — the shortest retention window of anything discussed here, so it’s the one most likely to already be gone if you’re only keeping the bare minimum. Beyond HOS, reviewers commonly ask for driver qualification files, vehicle maintenance records, and drug and alcohol testing records (retained one to five years depending on the specific record, under 49 CFR §40.333) — not usually BOLs themselves, which come up more in payment disputes than safety audits.

Digital records are legally acceptable

Nothing in Part 379 requires paper. Digital copies satisfy the retention requirement as long as they’re reasonably accessible and reproducible on request — a scanned BOL or a stored PDF rate confirmation counts the same as the original, provided you can actually pull it up when asked. The risk isn’t digital vs. paper, it’s whether the record is findable at all six months or three years later.

Quick reference: what to keep, how long

BOLs, rate confirmations, freight bills, shipper’s instructions: 1 year FMCSA minimum, 3+ years recommended in practice. HOS supporting documents (fuel/toll receipts, scale tickets): 6 months. Weight tickets: 3 years. Import/export and bonded freight records: 2 years. Freight loss/damage/injury claim records: 3 years. Drug and alcohol testing records: 1–5 years depending on record type.

The one-sentence version

The FMCSA floor for everyday shipping paperwork is one year, but three-plus years is the number that actually protects you against a late payment dispute or an IRS question — keep records digital, organized by load, and easy to pull up on request rather than technically compliant and impossible to find.
