Which agency is responsible for transportation security in the United States?

• A. Transportation Security Administration
• B. Aviation Security Authority
• C. Travel Safety Administration
• D. National Security Agency

Answer: (A)

Transportation Security Administration is responsible for transportation security in the United States. After 9/11, this agency was created within the Department of Homeland Security to coordinate and enforce security across the nation’s transportation system, including passenger and baggage screening at airports and security procedures for other modes of transit. The other options do not fit because they are either non-existent in relation to U.S. transportation security (Aviation Security Authority, Travel Safety Administration) or have a different focus (National Security Agency handles signals intelligence and cyber security, not general transport security).
