EDITORIAL STANDARDS
Every number on this site was opened at its source.
These guides tell carriers what federal rules require of them. A wrong threshold here becomes a wrong hiring policy there, so we publish the process, not just the promise.
What a guide passes through before it is published
Three stages. The second one is adversarial on purpose.
- 01Drafted against a briefThe brief names the CFR sections the guide will touch, the reader’s exact moment, and the questions our other site already answers so we do not repeat them.
- 02Checked by a second passA separate reviewer rebuilds the list of every number, date, threshold and section from the text itself, then opens each primary source. It is instructed to refute, not to confirm.
- 03Corrected, then publishedFindings are applied. A figure that cannot be opened at a federal source comes out of the text — it is never quietly replaced with an estimate.
The rule that decides everything else: if it cannot be opened at ecfr.gov, fmcsa.dot.gov or ftc.gov, the number does not ship. Describing the rule without the figure beats printing a figure we could not verify.
The trail, not the claim
Anyone can say their content is accurate. This is a sample of the record behind it — every figure with the section it came from, checkable in one click.
| WHAT THE GUIDE STATES | SOURCE | OPENED |
|---|---|---|
| Two serious violations in three years disqualify a driver for 60 days; three for 120. | 49 CFR 383.51 | ecfr.gov |
| The application covers three years of all employment, plus seven more years of CMV work only. | 49 CFR 391.21 | ecfr.gov |
| The driver’s own self-reporting duty was removed, effective July 22, 2026. | 91 FR 37047 | govinfo.gov |
| The revised SMS methodology is approved, but no launch date has been published. | Docket FMCSA-2022-0066 | govinfo.gov |
What we will not do
Commitments are easy to write. These are the four we can be held to.
- Invent an authorNo fabricated expert byline, no credentials nobody holds. If a named person reviews a guide, that is a real person you can look up.
- Rule on our own productWhether peer review data is a consumer report under the FCRA is a lawyer’s call, not a publisher’s. We tell you to ask yours.
- Print a figure we could not openIf the source will not load, the number comes out and the rule gets described in words instead.
- Tell you to skip a required checkEverything here sits alongside PSP, DAC, MVR and the Clearinghouse. Never instead of them.
Who publishes this
CDLScancdlscan.comCDLScan runs a peer-sourced database of carrier-reported driver reviews. These guides exist because the questions our users ask before they search a driver are the same questions nobody had answered plainly.
That gives us an interest, and it is better stated than hidden: we would like you to try the product. It is why the product is named in these guides, and why we hold it to the same rule as everything else — it sits alongside the checks the law requires, never in place of them.
Guides are researched and drafted against a brief, checked by a second independent pass against primary sources, corrected, and published under the CDLScan editorial team.
