What's the difference between a regular drug test and a DOT drug test?
What's the difference between a regular drug test and a DOT drug test? DOT tests almost always use urine specimens, while non-DOT drug tests may use urine, saliva, or hair based on the state's regulations. DOT testing uses a document called the Federal Drug Testing Control and Custody Form (CCF). In non-DOT testing, each state, employer, or drug testing company can develop its forms.
