DOT Investigations

The Office of Investigations is comprised of criminal and general investigators that are responsible for conducting criminal, civil, and administrative investigations of fraud and a variety of other allegations affecting DOT, its operating administrations, programs, and grantees (grant funds). The Office of Investigation’s top priorities involve crimes with a public safety impact, procurement and grant fraud schemes that significantly impact DOT funds, consumer and workforce fraud, and employee integrity violations. Learn more about OIG's investigative priorities, the investigative process, and common fraud schemes. The Office of Investigations also manages a Hotline Complaint Center and investigates whistleblower complaints, including those referred by the U.S. Office of Special Counsel.
