Transport and infrastructure

The NAO audits the accounts of the Department for Transport, its executive agencies and some public bodies it sponsors. The NAO also examines the systems that underlie the data collection for measuring the progress of the Department against its Public Service Agreement targets.

The NAO does not examine local transport expenditure directly, as Local Authorities spend that money, and they are audited by the Audit Commission. Transport matters outside England are audited by respective Audit offices.
