49 CFR Part 563 Event Data Recorders -- Final Rule; response to petitions for reconsideration

NOTE: In Table III of this document, the accuracy specification for the "Frontal air bag deployment, time to deploy/first stage, driver" should read +/- 2 ms. We have determined that the missing number is a typographical error that is not present in the originally signed notice. A correction notice to fix this error will soon be published in the Federal Register.
