Controlled Substances & Alcohol Violations
Drug & alcohol testing program, Clearinghouse queries, post-accident testing.
What this BASIC means
The Controlled Substances BASIC tracks 49 CFR Part 382 compliance: pre-employment drug test, random testing rate (50% annually for drugs, 10% for alcohol), post-accident testing, reasonable-suspicion testing, return-to-duty testing, and FMCSA Drug & Alcohol Clearinghouse queries. The Clearinghouse went live January 2020 — pre-employment query is now mandatory for every CDL holder. CSA threshold is 65th percentile (50th for hazmat). Drug/alcohol-related crashes are rare but catastrophic, so any violation here triggers serious FMCSA attention.

Top violations in this BASIC
382.305 (no random testing program) is the most-cited Controlled Substances violation, severity 10/10 and immediately ramps CSA scores. Other common: 382.701 (pre-employment Clearinghouse query missing, severity 6), 382.303 (post-accident testing not performed, severity 10), 382.213 (driving under controlled substance, OOS + lifetime CDL disqualification).
How to lower your Controlled Substances & Alcohol BASIC
Use a DOT-registered consortium/TPA for testing (DISA, eScreen, Quest Diagnostics' DOT program). The required testing categories: pre-employment (mandatory), random (50% drug, 10% alcohol annually), post-accident (after fatal crash, citation+injury crash, or citation+disabling crash), reasonable suspicion (supervisor observed), and return-to-duty (after positive test or refusal). Query the Clearinghouse pre-hire AND annually for existing drivers (since 2020). Document everything — DataQs reversals require paperwork.
