About this data

Every offense that triggers mandatory disqualification of a commercial driver's license (CDL) holder under 49 CFR 383.51, with the disqualification period for each combination of offense, vehicle type (CMV, non-CMV, hazmat), and occurrence count (first, second, third). Covers four federal tables: major offenses (DUI, leaving scene, felony — 1 year to lifetime), serious traffic violations (speeding 15+ mph, reckless driving, improper lane change — 60 to 120 days), railroad-highway grade crossing violations (60 days to 1 year), and violating out-of-service orders (180 days to 5 years). Answers 'my driver got a DUI in their personal car — is their CDL at risk?' with the exact period and the regulatory citation.

Where this came from

Every record above links the page it was taken from and quotes the sentence that states it. These are the 1 source this dataset was assembled from.

ecfr.govhttps://www.ecfr.gov/current/title-49/subtitle-B/chapter-III/subchapter-B/part-383/subpart-D/section-383.51

Machine-readable

data.jsonThe whole dataset — every record with its source URL and source quote.
Open Knowledge Format bundleOne JSON object per line — every record's frontmatter and quoted span exactly as it is held here, in one fetch.
data.csvThe same records as one flat table, for a spreadsheet or a dataframe. The last four columns are the source URL, the quoted sentence it was read from, the date we last checked it, and which columns are our reading rather than the page's words.
How this is made and checkedWhat "verified against source" does and does not mean.

From your own code

Same records, same quotes, without scraping the page: refsource is on PyPI and npm. Each value comes back carrying the URL it was read from and the sentence on that page that states it — .source and .quote sit on the value itself rather than in a side channel, so the checking step is available instead of skipped.

npx -y refsource lookup cdl-disqualification-offenses-and-periods offense_id=T1-bac-04-cmv-first

Set your AI assistant up to use this

Two files and no account. Put this in .mcp.json at the root of your project — Claude Code, Cursor, Windsurf, VS Code and Codex all read that file — and your assistant can look this dataset up instead of recalling it. The server is remote, keyless and read-only.

{
  "mcpServers": {
    "referencesource": {
      "type": "http",
      "url": "https://referencesource.org/mcp"
    }
  }
}

Add to Cursor · or, on the command line: claude mcp add --transport http referencesource https://referencesource.org/mcp --scope project

Then one line in the project's CLAUDE.md or AGENTS.md, so the assistant knows when to reach for it:

When a question needs "FMCSA commercial driver disqualification offenses and periods", call the referencesource MCP server at https://referencesource.org/mcp (tool `search_records`, dataset_slug `cdl-disqualification-offenses-and-periods`) instead of answering from memory — every record it returns carries its source URL and a verbatim quote from that page.

What each tool does, and the servers built over single registers: Connect your AI assistant.
