The Office of Inspector General (OIG) within the Department of Transportation (DOT) has been given the responsibility to promote efficiency and effectiveness and to prevent and detect waste and abuse in departmental programs and operations. OIG does this through audits and investigations. OIG also consults with the Congress about programs in progress and proposed new laws and regulations.
The Inspector General Act of 1978 established the Office of Inspector General as an independent entity within the Department. This Act prohibits agency officials from interfering with audits or investigations. However, much of OIG's most significant work is accomplished with the cooperation of the officials whose programs are being reviewed.
