OIG Hotline Complaint Center


The Office of Inspector General (OIG) maintains a Hotline to facilitate the reporting of allegations of fraud, waste, abuse, or mismanagement in U.S. Department of Transportation (DOT) programs or operations. You may report such allegations through the contact information listed on this page. Allegations may be reported by DOT employees, contractors, or the general public. OIG’s Hotline is open 24 hours a day, seven days a week and is operated by a third party contractor.

The OIG Hotline is obligated to expeditiously forward all safety-related complaints to DOT’s safety regulatory agencies.

Issues that should be reported:

  • Contract, Procurement, and Grant Fraud
  • Environment, Health, and Safety Violations
  • Computer Crimes
  • Product Substitution and Suspect/Counterfeit Parts
  • Bribery, Kickbacks, and Gratuities
  • False Statements and False Claims
  • Conflicts of Interest and Ethics Violations
  • Travel Fraud
  • Theft and/or Abuse of Government property
  • Other Violations of Federal Laws and Regulations

    Callers are encouraged to provide relevant and specific details of their complaints, including the identity of the person, company, or organization alleged to have engaged in wrongdoing; a description of the alleged impropriety; the DOT facility and program affected by the alleged misconduct; contract numbers; date(s) of alleged wrongdoing; how the caller is aware of the alleged impropriety; the identity of potential witnesses; and the identity and location of supporting documentation.

    Complaint processing:

    Upon receipt of a specific allegation of fraud, waste, abuse, or mismanagement, the OIG may take any one of the following actions: open an investigation or audit; refer the matter to DOT management for appropriate review and action; or refer the allegation to another Federal agency. Allegations with limited specificity or merit may be held in abeyance until further, specific details are reported.

    Callers may remain anonymous:

    Individuals who contact the Hotline, via telephone or letter, are not required to identify themselves to the Hotline operator. However, persons who report allegations are encouraged to identify themselves in the event additional questions arise as the OIG evaluates or pursues their allegations.


    The Office of Inspector General will protect the identity of complainants to the maximum extent possible by law. Confidentiality is established by Section 7(b) of the Inspector General Act of 1978, which precludes the IG from disclosing the identity of a DOT employee who reports an allegation or provides information, without the employee's consent, unless the IG determines that disclosure is unavoidable during the course of the investigation. Non-Department of Transportation employees who report allegations may specifically request confidentiality.
