DOT Drug Testing Consortium vs. TPA: Which Does Your Fleet Need? (2026)

Quick Answer

Yes. Every driver who operates a commercial motor vehicle (CMV) requiring a CDL in interstate commerce must be included in a DOT random drug and alcohol testing pool under 49 CFR Part 382. This applies to part-time drivers, seasonal drivers, and drivers classified as independent contractors if the carrier has actual control or right to control their driving duties.
