The National Highway Traffic Safety Administration (NHTSA) is proposing to amend regulation for Event Data Recorders (EDR’s). This would extend the recording period for timed data metrics from 5 seconds of pre-crash data at a frequency of 2Hz to 20s of pre-crash data at a frequency of 10Hz. The Notice of Proposed Rulemaking (NPRM) appeared in the June 22, 2022 Federal Register (F.R. Vol. 87 No. 119; 49 CFR Part 563; Docket No. NHTSA-2022-0021).

This regulation applies to the following vehicles manufactured after the compliance date, if they are equipped with an event data recorder:

  • Passenger cars
  • Multipurpose passenger vehicles
  • Trucks and buses with a gross vehicles weight rating (GVWR) of 3,855kg (8,500lb) or less and an unloaded vehicle weight of 2,495kg (5,500 lb) or less, except for walk-in-van-type trucks or vehicles designed to be sold exclusively to the U.S postal service.

This also applies to manufacturers of those vehicles however, vehicles manufactured before September 1 2013, in two or more stages or are altered (within the meaning of 49 CFR 567.7) after being previously certified to the Federal Motor Vehicle Safety Standards (FMVSSs) in accordance with part 567, need not meet the requirements of this part.
