IV.  Submission of Comments


    How do I prepare and submit comments?

    Your comments must be written and in English. To ensure that your comments are filed correctly in the Docket, please include the docket number of this document in your comments.

    Your comments must not be more than 15 pages long. (49 CFR 553.21)  NHTSA established this limit to encourage you to write your primary comments in a concise fashion. However, you may attach necessary additional documents to your comments. There is no limit on the length of the attachments.

    Please submit two copies of your comments, including the attachments, to Docket Management at the address given above under ADDRESSES. You may also submit your comments to the docket electronically by logging onto the Docket Management System (DMS) website at http://dms.dot.go. Click on "Help & Information" or "Help/Info" to obtain instructions for filing your comments electronically. Please note, if you are submitting comments electronically as a PDF (Adobe) file, we ask that the documents submitted be scanned using Optical Character Recognition (OCR) process, thus allowing the agency to search and copy certain portions of your submissions. [17]  

    How can I be sure that my comments were received?

    If you wish Docket Management to notify you upon its receipt of your comments, enclose a self-addressed, stamped postcard in the envelope containing your comments. Upon receiving your comments, Docket Management will return the postcard by mail.

    How do I submit confidential business information?

    If you wish to submit any information under a claim of confidentiality, you should submit three copies of your complete submission, including the information you claim to be confidential business information, to the Chief Counsel, NHTSA, at the address given above under FOR FURTHER INFORMATION CONTACT. In addition, you should submit two copies, from which you have deleted the claimed confidential business information, to Docket Management at the address given above under ADDRESSES. When you send a comment containing information claimed to be confidential business information, you should include a cover letter setting forth the information specified in NHTSA’s confidential business information regulation (49 CFR Part 512).

    Will the agency consider late comments?

    NHTSA will consider all comments that Docket Management receives before the close of business on the comment closing date indicated above under DATES. To the extent possible, the agency will also consider comments that Docket Management receives after that date. If Docket Management receives a comment too late for the agency to consider it in developing a final rule (assuming that one is issued), the agency will consider that comment as an informal suggestion for future rulemaking action.

    How can I read the comments submitted by other people?

    You may read the comments received by Docket Management at the address given above under ADDRESSES. The hours of the Docket are indicated above in the same location.

    You may also see the comments on the Internet. To read the comments on the Internet, take the following steps:

    1. Go to the Docket Management System (DMS) Web page of the Department of Transportation (http://dms.dot.gov).

    2. On that page, click on "search."

    3. On the next page ( http://dms.dot.gov/search), type in the four-digit docket number shown at the beginning of this document. Example:  If the docket number were "NHTSA-1998-1234," you would type "1234." After typing the docket number, click on "search."

    4. On the next page, which contains docket summary information for the docket you selected, click on the desired comments. You may download the comments. Although the comments are imaged documents, instead of word processing documents, the "pdf" versions of the documents are word searchable.

    Please note that even after the comment closing date, NHTSA will continue to file relevant information in the Docket as it becomes available. Further, some people may submit late comments. Accordingly, the agency recommends that you periodically check the Docket for new material.

    Anyone is able to search the electronic form of all comments received into any of our dockets by the name of the individual submitting the comment (or signing the comment, if submitted on behalf of an association, business, labor union, etc.). You may review DOT's complete Privacy Act Statement in the Federal Register published on April 11, 2000 (Volume 65, Number 70; Pages 19477-78) or you may visit http://dms.dot.gov.

    § 563.1 Scope.

    This part specifies uniform, national requirements for vehicles equipped with event data recorders (EDRs) concerning the collection, storage and retrievability of onboard motor vehicle crash event data. It also specifies requirements for vehicle manufacturers to make publicly available information that would enable crash investigators and researchers to retrieve data from EDRs.

    The purpose of this part is to help ensure that EDRs record, in a readily usable manner, the data necessary for effective crash investigations, analysis of the performance of safety equipment, e.g., advanced restraint systems, and automatic crash notification systems. These data will help provide a better understanding of the circumstances in which crashes and injuries occur and will lead to the designing of safer vehicles.

    § 563.3 Application

    This part applies to passenger cars, multipurpose passenger vehicles, trucks, and buses with a GVWR of 3,855 kg (8500 pounds) or less and an unloaded vehicle weight of 2,495 kg (5500 pounds) or less, except for walk-in van-type trucks or vehicles designed to be sold exclusively to the U.S. Postal Service, that are equipped with an event data recorder (EDR) and to manufacturers of these vehicles.

    § 563.11  Information in owner’s manual.

    The owner’s manual must contain the following statement:  "This vehicle is equipped with an event data recorder. In the event of a crash, this device records data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less.
