When will DOT oral fluid drug testing be operational for DOT employers?

The final rule for DOT oral fluid drug testing takes effect June 1, 2023. No labs are currently certified for oral fluid drug testing so it will take a while before we actually see DOT oral fluid drug testing actually being used. This will more than likely be later 2023 or early 2024, there is no way to predict more accurately.
