Is oral the most reliable?!

The U.S. Department of Transportation (DOT) is taking direct final action to revise DOT's drug testing procedures rule, which became effective on June 1, 2023, to provide temporary qualification requirements for mock oral fluid monitors, provide for consistent privacy requirements by identifying which individuals may be present during an oral fluid collection, and clarify how collectors are to specify that a sufficient volume of oral fluid was collected.

This final rule is effective on August 5, 2024, without further notice unless DOT receives adverse comment by July 22, 2024. If DOT receives adverse comment on any of the provisions in this direct final rule, it will publish a timely withdrawal in the Federal Register informing the public that the provisions of the rule on which adverse comment were received will not take effect.
