This Marine Safety Advisory is to ensure mariners, marine employers, and sponsoring organizations are informed of recent changes to the Department of Transportation Drug Testing requirements. As the U.S. Coast Guard requires a DOT drug test, this MSA seeks to broadly communicate important changes effecting mariners, marine employers, and sponsoring organizations.
