		The National Transportation Safety Board, an independent federal agency, has the authority to promote motor vehicle safety, determine the probable cause of motor vehicle-related crashes, and make safety recommendations aimed at preventing crashes. Over the years, NTSB has made recommendations to NHTSA, the federal agency that sets and enforces vehicle safety standards and works to reduce traffic deaths and injuries. Below is a list of open recommendations. Please note, NTSB recommendations often involve rulemaking activities, which can be multi-phase and multi-year efforts.
