Commercial drivers may get their DOT physicals and drug testing is done at the same time at a walk-in clinic. As you’ll learn when you watch this video, DOT drug and alcohol testing are significantly different from non-DOT testing. DOT tests are subject to far stricter regulations. This underscores the importance of choosing a clinic that specializes in DOT medical requirements.
For example, it is not permitted to perform drug and alcohol screenings on the same individual for both DOT and non-DOT purposes at the same time. The samples used for DOT tests cannot be used for non-DOT tests. Additionally, the results of a non-DOT test cannot supersede the results of a DOT test.
