These rules are modifications to existing drug and alcohol driver testing procedures. Many drivers are unaware of the rules and their implications. Not only are mandatory drug and alcohol testing a requirement for every employed CDL driver, but there are extensive new paperwork and record keeping requirements and new mandatory drug and alcohol education programs. In a short article we can't describe everything contained in a 323-page set of rules, but we will give you enough information so that you can explain the basics of the act and its implications for you.
Driver means any person who operates a commercial motor vehicle.
Note that only drivers are subject to the act. Understand that the moment anyone gets behind the wheel of a vehicle that can be driven only by someone who possesses a valid CDL, that driver and employer come under the act whether properly licensed or not. These rules preempt all state alcohol and substance abuse driving laws. No on-duty use of drugs or alcohol permitted. No alcohol consumption within four hours of performing a safety sensitive function or within eight hours following an automobile accident.
