The Rest of the Departments Practice Test

Transportation safety investigations are led by the National Transportation Safety Board. The NTSB investigates civil transportation accidents across air, highway, rail, marine, and pipeline modes, determines probable causes, and issues safety recommendations to prevent future incidents. This focus on investigating accidents and improving safety distinguishes it from other agencies: the FDIC oversees banking and deposit insurance, FEMA handles emergency management and disaster response, and the Department of Homeland Security concentrates on national security and protective functions. So the NTSB is the agency most closely associated with transportation safety investigations.
