49 CFR Part 575

[Docket No. NHTSA-2000-6859; Notice 2]

RIN 2127-AC64


Consumer Information Regulations; Federal Motor Vehicle Safety 
Standards; Rollover Prevention

AGENCY: National Highway Traffic Safety Administration (NHTSA), DOT.

ACTION: Extension of comment period.

-----------------------------------------------------------------------

SUMMARY: This document grants a request by the Alliance of Automobile 
Manufacturers to extend, for 30 days, the comment period on the 
agency's request for comment on the proposal to include ratings for 
rollover resistance in the New Car Assessment Program.

DATES: The comment period will close on August 30, 2000.

ADDRESSES: Comments should refer to Docket No. NHTSA-2000-6859 and be 
submitted to: Docket Management, Room PL-401, 400 Seventh St, SW, 
Washington, DC 20590. Docket room hours are from 10:00 a.m. to 5:00 
p.m., Monday through Friday.

FOR FURTHER INFORMATION CONTACT: Gayle Dalrymple, Office of Crash 
Avoidance Standards 202-366-5559 or by FAX to 202-493-2739. The mailing 
address is National Highway Traffic Safety Administration, NPS-23, 400 
Seventh St, SW, Washington, DC 20590.

SUPPLEMENTARY INFORMATION: On Thursday, June 1, 2000, NHTSA published a 
request for comment on the agency's intent to include a vehicle measure 
of rollover resistance, its Static Stability Factor (SSF), as an 
addition to the New Car Assessment Program (NCAP).
    The agency believes that consumer information on the rollover risk 
of passenger cars and light multipurpose passenger vehicles and trucks, 
based on the vehicle's SSF, would reduce the number of injuries and 
fatalities from rollover crashes. This information would enable 
prospective purchasers to make informed choices about new vehicles 
based on differences in real-world rollover risk and serve as a market 
incentive to manufacturers in striving to design their vehicles with 
greater rollover resistance.
    Included in the notice was a new statistical study undertaken to 
demonstrate a relationship between SSF and rollover rate representative 
of the whole country. A relationship between rollover rate and SSF 
normalized to the national rollover rate and to a nationally 
representative set of driver and road use variables was developed as a 
basis for a comparative rating system for rollover risk in the event of 
a single-vehicle crash. We had available crash reports of 185,000 
single-vehicle crashes from six states from 1994 to 1997 in which it 
was possible to determine the make/model of the vehicles and whether 
rollover occurred in the course of a single-vehicle crash, and for 
which SSF data were also available. We also had the NASS GES data 
sampling system, with far fewer but nationally representative crash 
reports, to determine the national average rollover rate for the 
population of vehicles investigated in the state reports.
    The notice specified a comment closing date of July 31, 2000 (60 
days after date of publication). However, on July 10, 2000 we received 
a request for an extension of the comment closing date from the 
Alliance of Automobile Manufacturers (AAM). The AAM stated that it 
would need an additional 30 days to allow for replication and analysis 
of the statistical study presented in the appendix to the notice.
    NHTSA wants the public to have adequate time to analyze the 
statistical study and other facts that are the basis for our proposed 
rollover rating system. The request for an additional 30 days

[[Page 46885]]

does not seem excessive. Thus, in order to provide the AAM and other 
interested parties ample time and opportunity to analyze the study 
presented in the notice and to express their views on the proposal, 
NHTSA believes that there is good cause for the extension of the 
comment period and that such extension in consistent with the public 
interest. Accordingly, the AAM request to extend the comment period for 
an additional 30 days is granted. The comment period will now close 
August 30, 2000.

    Authority: 49 U.S.C. 322, 30111, 30115, 30117, and 30166; 
delegation of authority is at 49 CFR 1.50.

    Issued on: July 26, 2000.

Associate Administrator for Safety Performance Standards.
