Which acronym stands for the agency responsible for security in US transportation?

• A. FAA
• B. NTSB
• C. DHS
• D. TSA

Answer: (D)

Transportation security in the U.S. is handled by the Transportation Security Administration, or TSA. TSA focuses on screening passengers and baggage and implementing security procedures at airports and other transportation hubs, making it the agency tasked with day-to-day security in travel. It operates under the Department of Homeland Security, which oversees national security, but the specific responsibility for transportation security is carried out by TSA. The FAA governs safety and regulation of air travel (airspace and aircraft operations), while the NTSB investigates accidents and issues safety recommendations. So, TSA is the agency dedicated to transportation security.
