The audit letter decides whether you keep your authority.

New-entrant safety audit, compliance review, or focused audit — an FMCSA investigator reviews your records across six factor areas. Most carriers find out where they stand when the auditor shows up. X3 asks the investigator's questions first, so you already know — and fix — every gap before it counts.

FAQ

Questions carriers ask about audits.

+What does an FMCSA audit actually check?
An investigator reviews six factor areas: your drug & alcohol program, driver qualifications (CDLs, medical certs, DQ files), hours-of-service records, vehicle maintenance and inspections, your accident register, and operating authority/insurance. X3 grades you on each one, flags the acute items first, and cites the governing rule.
+How is the Audit Simulator different from a checklist?
It behaves like an investigator. You answer the questions an auditor asks, X3 pulls your live public CSA record, and you get Green/Yellow/Red on every factor plus an estimated pass probability and the priority fixes — each routed to the X3 product that owns the fix.
+I got a Notice of Investigation / warning letter. Can X3 help?
Yes. Paste it into the Defense Assistant and X3 explains what it means, the likely consequences, the deadline and your priority actions — plain English, cited to the rule. It's a draft you confirm, not legal advice; for a formal legal response we hand off to X3 Legal.
+Does X3 DOT Audit replace my other compliance tools?
No — it's the control tower. It reads signals from across your program and routes every deep fix to the product that owns it (Background for DQ files, MVR for reviews, HOS for logs, Drug & Alcohol, DataQ, Preventability, CSA and more). It never rebuilds them.
+Is this legal advice or an FMCSA service?
No. X3 DOT Audit is a compliance-preparation tool from X3 Fleet Safety LLC — not legal advice, and not affiliated with FMCSA or USDOT. FMCSA conducts the official audit and no outcome is guaranteed. Every answer is grounded in verified 49 CFR and cited to the rule; verify results against the current regulations before relying on them.
Never be surprised by an audit again.

Run your mock audit today and know exactly where you stand — and what to fix first — before FMCSA ever calls.
