What does 'NTSB' stand for?

The correct response is based on the official designation of the organization that investigates civil transportation accidents and promotes safety in the transportation sector. 'NTSB' stands for the National Transportation Safety Board. This independent federal agency is responsible for determining the probable cause of transportation accidents, including aviation incidents, and making recommendations to improve safety across all modes of transportation.

This name emphasizes both the breadth of the agency's focus on transportation safety across various sectors and its role in the investigative and regulatory processes. Understanding the functions and responsibilities of the NTSB is crucial for those involved in aviation and transportation, as it highlights the importance of safety protocols and compliance with federal regulations.
