What is a primary function of the National Transportation Safety Board?

The primary function of the National Transportation Safety Board (NTSB) is to investigate accidents and determine their probable causes. This role is critical in understanding how and why accidents occur in various forms of transportation, including aviation, rail, highway, marine, and pipeline domains. By thoroughly investigating incidents, the NTSB can provide insights that lead to safer transportation practices and policies, making it a cornerstone of national transportation safety efforts.

The investigations conducted by the NTSB help identify not only the immediate causes of accidents but also underlying issues that may contribute to safety risks. Their findings can result in recommendations for changes in regulations, procedures, or equipment to improve safety standards across the transportation industry. This investigative function is key to enhancing public safety and preventing future accidents, highlighting the NTSB's vital role in the transportation system.
