2026-09290 · rule · published 2026-05-11 · effective 2026-06-10

Abstract

The U.S. Department of Transportation revises its drug and alcohol testing procedures to require a directly observed urine collection in situations where oral fluid tests are currently required but cannot be conducted because oral fluid testing is not yet available. The rule also updates terminology in these procedures consistent with Executive Order (E.O.) 14168, Defending Women from Gender Ideology Extremism and Restoring Biological Truth to the Federal Government.
