For AI assistants

The free tools, from inside ChatGPT or Claude.

Three of our free calculators are available to AI assistants through the Model Context Protocol (MCP). Ask your assistant about your new-entrant audit or your random testing pool, and it can run the same math as the tools on this site, with the regulation cited beside every number.

Tools

  • 49 U.S.C. §31144(g) · 49 CFR §385.307

    new_entrant_audit_timeline

    From the month a USDOT number went active: when the new-entrant safety audit window closes, when the 18-month monitoring period ends, and how many months are left in each. Property carriers; passenger carriers are on a 120-day audit clock this does not cover.

  • 49 CFR §385.321(b)

    list_audit_readiness_questions

    The questions behind the audit readiness check, each with its CFR cite, what the auditor asks to see, and whether it is on the §385.321(b) automatic-failure table.

  • 49 CFR Parts 382, 383, 387, 390, 391, 395, 396

    score_audit_readiness

    Scores the answers and returns the gaps to close first, the other gaps, and a next step for each. A flagged item is a priority, not a predicted audit outcome.

  • 49 CFR §382.305(b), (j)(2)

    random_testing_minimums

    From the average number of driver positions: the minimum random drug tests (50%) and alcohol tests (10%) for the year at FMCSA's 2026 rates, rounded up. In a consortium pool the rate applies to the consortium's larger pool.

All four are read-only: they compute from what you pass in and change nothing.

Try asking

  • My USDOT number went active in March 2026. When will my new entrant safety audit happen, and how long am I a new entrant?
  • Walk me through the new entrant audit readiness questions, then tell me what to fix first.
  • I have 4 CDL drivers all year. How many random drug and alcohol tests does FMCSA require?

Your data

The server needs no account and cannot see any Roadworthy HQ workspace. It receives only the inputs a calculator needs (a month, your readiness answers, or a driver count), uses them to compute the answer, and does not store them. Each call is counted anonymously by tool name. Please leave personal details out of your requests. Details are in section 13 of the Privacy Policy.

Not legal advice. Roadworthy HQ is a record-keeping aid; the regulations, your FMCSA notices, and your registration paperwork control. Questions: support@roadworthyhq.com.
