A DER Mistake at 2:00 AM Can Become an Audit Finding at 2:00 PM.
Post-accident calls don't come during business hours. And when they do come, the DER is expected to act quickly and correctly.
Common DER errors that surface during audits:
• Failing to initiate testing within the required DOT timelines.
• Not properly removing an employee from safety-sensitive duties after receiving a verified positive result.
• Accepting a test result without confirming MRO verification.
• Missing Clearinghouse reporting deadlines.
• Incomplete documentation of reasonable suspicion observations.
These aren't hypothetical. They're the most frequent findings in DOT compliance reviews.
The DER role requires knowledge, process discipline, and support. That starts with proper training — and NMS offers online courses built specifically for DERs and compliance professionals.
