As of May 02, 2023, The Department of Transportation (DOT) came down to its final rule amending the DOT's regulated industry drug testing program. The DOt's drug testing program will now include an oral test. With this change, there are a few things you need to know. Such as when the final rule will be effective and who can implement the DOT-regulated oral test.
This DOT Final Rule Oral Testing will begin to take effect on June 1, 2023. Even though it will take effect on June 1, 2023, it does not mean any drug testing facilities will begin to take oral examinations for DOT. In accordance with the DOT the Department of Health and Human Services (HHS) must certify two laboratories. One laboratory must be the primary and the second will serve for split specimen laboratory testing. If you need To check if your laboratory is HHS certified you may do so through this link: https://www.transportation.gov/odapc/labs. If your lab does not appear on the list you will need to find a location with a lab that is certified in order to get the DOT oral test.
