Procedures for Transportation Workplace Drug and Alcohol Testing Programs
The Department of Transportation is amending certain provisions of its drug and alcohol testing procedures to change instructions to laboratories and medical review officers with respect to adulterated, substituted, and diluted specimen results. This change is intended to avoid inconsistency with new requirements established by the U.S. Department of Health and Human Services that went into effect on November 1, 2004.
