During a compliance review, FMCSA investigators will ask for:
Your written drug and alcohol testing policy
Random pool documentation and draw records
Chain of custody forms for completed tests
Clearinghouse query records -- both for current drivers and anyone hired recently (this is where most carriers come up short)
Supervisor reasonable suspicion training certificates
Records of any violations, plus what Return-to-Duty steps were taken
Can't produce the paperwork? That's a finding.
It doesn't matter if you ran the program perfectly. Without documentation, FMCSA treats it as if you didn't. A lot of carriers had a program running but couldn't prove it when it counted. Records missing equals program missing.
“The most common finding we see is carriers who have a program but can't produce the records to prove it. Documentation is everything in an FMCSA audit.”
Closing the Gaps Before FMCSA Finds Them
The carriers who come through compliance reviews clean aren't necessarily bigger or better-staffed. They have systems that catch problems before an auditor does. Foley's Dash platform tracks every test, every draw, every Clearinghouse query -- and flags anything missing or overdue. The auditor shows up. The documentation is already there.
The fine isn't for having a bad program. It's for not being able to prove you had a good one.
