General Information
A Controlled Substances and Alcohol Testing Program is required for all motor carriers, including owner-operators, who operate vehicles which require a CDL.
The Controlled Substances and Alcohol Testing Program consists of pre-employment, random, and post-accident testing along with specialized testing required to return drivers to full duty.
Along with required testing, the motor carrier is required to have supervisors who are trained to detect if any of their drivers may be under the influence of any controlled substances or alcohol while on duty.
