As part of its statutory mandate, the ISAU seeks to prevent, detect and correct fraud, waste and abuse in the expenditure of public and private transportation funds. The ISAU is also responsible for examining and evaluating the adequacy and effectiveness of MassDOT’s operations, including its governance, risk-management practices and internal processes. It is the Office's practice to maintain the names of all complainants in confidence. Individuals are encouraged to report suspected fraud, waste and abuse of transportation funds by confidential email, telephone or mail.
