National Highway Traffic Safety Administration December 18, 2024 – Federal Register Recent Federal Regulation Documents

This final rule amends regulations regarding event data recorders (EDRs) to extend the EDR recording period for timed data metrics from 5 seconds of pre-crash data at a frequency of 2 Hz to 20 seconds of pre-crash data at a frequency of 10 Hz. This final rule responds to the mandate of the Fixing America's Surface Transportation Act (FAST Act) to establish the appropriate recording period in NHTSA's EDR regulation.
