DOT Record Retention Requirements: How Long to Keep Every File

Retention is the quiet half of compliance. A carrier can collect every required document and still take a finding because the file was thrown out too early — or because it was kept somewhere nobody could find it.

Retention at a glance

Always confirm the current period in the regulation that applies to your operation; retention rules differ by record type and by the authority you operate under.

Why the clock is easy to lose

Each row above starts on a different event: a hire date, a termination date, an inspection date, a vehicle's out-of-service date, a test date. A paper system tracks none of those automatically, so retention becomes an annual cleanup decision made from memory.

Two failure modes follow. Files get purged early, or nothing is ever purged and the archive becomes unsearchable — which is functionally the same problem when a request arrives with a deadline.

Electronic recordkeeping done properly

Electronic storage is permitted and, at any fleet size beyond a handful of drivers, it is the only sustainable option. What makes it defensible:

• Every document is attached to the right driver or unit, not to a folder someone named.
• Dates are stored as data — issue date, expiry date, review date — so retention and expiry can be calculated rather than remembered.
• Access is restricted, especially for medical and drug and alcohol records.
• The file can be reproduced on request in a legible form, complete with the dates.
• A backup exists that is not the same laptop as the original.

Retiring records without losing them

Do not treat retention as deletion. Treat it as archiving with a reason:

1. Set the retention window per record type when the document is filed.
2. Keep former-driver files in place until the window closes — do not move them to a "left the company" folder that no one indexes.
3. When a window does close, record what was retired and when, so the absence of a record has an explanation.

CabFiles stores every document in a private, per-company archive with the dates it needs to calculate expiry and retention, keeps former drivers' files intact, and produces a complete, indexed export when someone asks. See driver document management for how that archive works day to day.

Why retention failures look worse than they are

Most retention problems are not deliberate. A driver leaves, someone tidies the cabinet, and three years later an investigator asks for that file. The finding is recorded as missing records, which reads far worse than the reality of a well-run carrier with an untidy archive.

The fix is to separate "active" from "retained" instead of "keep" from "discard". A former driver's file should move out of the working set but stay in the archive with its retention clock attached, so nothing is deleted by judgement in a busy week.

Electronic storage, done defensibly

Electronic records are acceptable when they are accurate, retrievable on request and reproducible in a legible form. In practice that means three things: the file is stored as the document it is, the dates are recorded alongside it, and access is restricted to the people who need it. Photographs of paper are fine if they are legible in full.

Two habits matter more than the storage technology. First, never overwrite a record when it is replaced — file the new one and keep the old, so history is visible. Second, keep the trail of who changed what, which is exactly what an investigator asks when a date looks inconsistent.

A simple retention routine

Once a quarter, review who left, confirm their files moved to the archive with the retention date attached, and confirm nothing inside the retention window was removed. Ten minutes a quarter is the entire discipline.

Retention periods here are a general summary. Verify the current requirement for your operation in the applicable regulation.
