49 CFR Part 40.323 allows you, as an employer, to release information pertaining to an employee’s drug or alcohol test without the employee’s consent in certain legal proceedings. These proceedings include a lawsuit, grievance or administrative proceeding (e.g., unemployment compensation hearing) brought by, or on behalf of, an employee and resulting from a positive DOT drug or alcohol test or a refusal to test (including, but not limited to, adulterated or substituted test results).
