What does "NTSB" stand for?

The acronym "NTSB" stands for the National Transportation Safety Board. This agency is an independent U.S. government investigative body responsible for determining the probable cause of transportation accidents, including aviation incidents. The NTSB conducts detailed investigations, issues safety recommendations, and strives to improve safety across all modes of transportation. Its findings and recommendations play a significant role in shaping transportation policy and enhancing safety protocols.

In contrast, the other options provided do not accurately reflect the mission or title of the NTSB. The National Technical Safety Bureau and the National Testing Safety Bureau are not recognized entities in the context of transportation safety. Similarly, the National Traffic Safety Board does not exist in that form, though there is a National Highway Traffic Safety Administration (NHTSA) that focuses on road safety, but it does not encompass all transportation modes like the NTSB does. Understanding the role and designation of the NTSB is crucial for anyone involved in aviation and transportation safety.
