What key aspect is NOT a focus of the National Transportation Safety Board?

The National Transportation Safety Board (NTSB) primarily focuses on the investigation and analysis of transportation accidents to enhance safety measures and to determine the probable causes of these incidents. Their mission includes conducting thorough investigations that help establish facts and factors contributing to accidents, making recommendations to prevent future occurrences.

Issuing transportation regulations is outside the scope of the NTSB’s primary responsibilities. Instead, regulatory functions are typically the purview of agencies such as the Federal Aviation Administration (FAA) for aviation, or the Federal Motor Carrier Safety Administration (FMCSA) for commercial vehicle regulations. The NTSB does not create or enforce regulations; rather, it serves as an investigative body that provides safety recommendations based on its findings. By identifying what went wrong in transportation accidents, the NTSB aims to influence regulatory agencies and improve safety standards indirectly.
