DHS Does Not Adequately Manage or Have Enforcement Authority Over Its Components' Vehicle Fleet Operations

In fiscal year 2012, Federal agency fleets consisted of more than 650,000 motor vehicles around the world. The Department of Homeland Security (DHS) had the second largest civilian motor vehicle fleet in the Federal Government, owning or leasing about 56,000 vehicles, with reported annual operating costs of about $534 million. Our audit objective was to determine whether, for fiscal year 2012, DHS met requirements to right-size its motor vehicle fleet composition, eliminate underused vehicles, and acquire vehicles that reduce petroleum use and greenhouse gas emissions.
