Mock Audits

How a Mock Audit Saves You From a Real One

Every FMCSA compliance review I've seen up close β€” and I've been in a lot of rooms β€” has the same shape: an investigator with a checklist, a stack of files on a folding table, and a series of "can you show me…" questions. The good ones are professional, fair, and methodical. The bad ones are looking for the gap.

A mock audit gives you the same experience without the consequences. Here's what we actually do.

Files we review

The exact same ones an FMCSA Safety Investigator would pull:

  • Every Driver Qualification file β€” application, releases, MVRs, medical card with National Registry verification, road test, annual driver review, certificate of violations
  • Every Clearinghouse query β€” pre-employment full, annual limited, since-hire
  • Drug & alcohol records β€” random pool documentation, every test result, chain-of-custody, MRO verifications
  • Hours of Service records for the past 6 months, plus supporting documents (BOLs, fuel receipts, payroll, toll records)
  • Vehicle file β€” annual periodic inspections, DVIRs, maintenance program documentation
  • Accident register and Preventable/Non-Preventable determinations
  • Roadside inspection history and DataQ challenges
  • Written safety policies β€” drug & alcohol, cell phone, discipline, harassment

What we look for

The gaps that auditors hit hardest:

  1. DQ files missing the SPHR response β€” most-cited finding by a wide margin
  2. Missing annual limited Clearinghouse queries β€” second-most-cited
  3. HOS supporting documents that don't match the logs β€” fuel timestamps in wrong location, missing BOLs
  4. Missing MEC + missing National Registry verification β€” common after MEC re-certifications
  5. Vehicle files without the annual inspection β€” especially on owner-operator trailers
  6. Accident register entries without preventability determinations

What you get

A written findings report with each gap prioritized by audit severity. A corrective action plan for each one. And β€” if you're a Patron client β€” we fix the gaps for you and ship you the audit-ready files.

If we're being honest: the carriers who run an annual mock audit basically never have findings on a real audit. The investigator opens the file, sees the SPHR response from every prior employer, sees the annual queries on schedule, sees the road test certificates, and closes the file. That's the whole point.

The mock audit is the cheapest insurance policy in compliance. Schedule one before you need one.
