The National Transportation Safety Board (NTSB) is an independent U.S. government agency responsible for investigating transportation accidents. This includes incidents involving airplanes, trains, ships, and highways. The NTSB's primary goal is to improve safety by determining the causes of accidents and making recommendations to prevent future occurrences. Established in 1967, the NTSB conducts thorough investigations and issues reports that often lead to changes in laws and regulations. The agency also provides assistance to victims and their families after major accidents. By focusing on safety improvements, the NTSB plays a crucial role in enhancing the overall safety of the nation's transportation systems.
