The Guardian Medal was awarded to senior government officials who, through visionary leadership, redirected the focus and resources of their organization, or major entities within their organization, and whose efforts had a profound impact in their field, the Federal Government, or on the public in providing for the protection and security of the United States and its citizens.

To justify this decoration, nominations must have demonstrated exceptional performance of duty while in a position of great responsibility, clearly above that normally expected, which has contributed materially to the betterment of the United States.

The Secretary of Transportation presented this award to those persons in national level positions of great responsibility.

The front face of the medal depicts, from the waist up, a colonial minuteman holding a flag.

This also has a raised rim, which reads, "For service to the U.S. Department of Transportation in guarding the interests of the American public".
