Controlled Substances and Alcohol BASIC

By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team

Definition

Controlled Substances and Alcohol is the CSA BASIC tracking driver-side violations of FMCSA drug and alcohol rules at roadside - primarily roadside post-accident testing failures and on-duty intoxication signs. The Drug & Alcohol Clearinghouse handles employer-side reporting separately. Violations in this BASIC carry the highest severity weights (10) because of the public-safety risk. Even a single violation can move a small carrier from clean status to alert threshold. Carriers should pair ELD/HOS compliance with a robust C/TPA-administered random-testing program and Clearinghouse-query workflow to keep this BASIC clean.
