NHTSA Event Data Recorders Rule
Current understanding
NHTSA regulates event data recorders (EDRs) in light motor vehicles under 49 CFR Part 563, specifying the data elements, capture, and survivability requirements when EDRs are voluntarily installed. A final rule updates EDR requirements, adjusting technical specifications and compliance obligations for manufacturers. Practical effect: standardizes crash-relevant data available to investigators and researchers without mandating installation.
