The Subcommittee met, pursuant to notice, at 10 a.m. in room SR–253, Russell Senate Office Building, Hon. Mark Pryor, Chair- man of the Subcommittee, presiding. OPENING STATEMENT OF HON. MARK PRYOR, U.S. SENATOR FROM ARKANSAS Senator PRYOR. Let’s go ahead and call the meeting to order. I’d like to welcome everyone here today, especially Senator Coburn. We’re going to let him go first. But, let me just give, if I may, give a brief opening statement. I know that Senator Coburn has other commitments he has to get to. Today we’re going to talk about automobile safety, and we’ll focus on the NHTSA rulemaking on vehicle roof strength standards to protect automobile passengers in the event of rollover accidents. The hearing will look at the biomechanics and what actually oc- curs in a rollover, the relationship between the vehicle roof strength and the occupant injury risk, the history and efficacy of the National Highway Traffic Safety Administration’s roof strength standard in improving vehicle safety, and a review of the January 30, 2008, Supplemental Notice of Proposed Rulemaking. The agen- cy’s deadline for issuing the final rule is July 1 of this year—which is just in—what, I guess 4 weeks from now or less—with a legally permissible extension, if necessary. Just in terms of background, this agency has the responsibility of trying to make our vehicles safer, and thousands of Americans are killed and injured each year in motor vehicle accidents. The agency reported that—42,642 highway-related fatalities and 2,575,000 injuries in 2006. Of the 42,000 fatalities, about 10,000— a little more than 10,000 were killed by rollover crashes, and 2,007 people sustained injuries due to rollover crashes. The majority of rollovers occur when a driver loses control of the vehicle, causing the vehicle to begin sliding sideways. Typically, something triggers the vehicle to begin rolling. The trigger could be a tripping object, such as a curb or a guardrail, or even soft and uneven ground at the side of the roadway, like the shoulder. An- other trigger for rollover could be an attempt by the driver to make (1) VerDate Nov 24 2008 11:24 Aug 23, 2012 Jkt 000000 PO 00000 Frm 00005 Fmt 6633 Sfmt 6633 S:\GPO\DOCS\75609.TXT JACKIE 2 an overly aggressive turn of the vehicle, either at a high velocity or at a tight turning radius. ‘‘Roof crush’’ describes the vehicle’s roof as it is deformed during a rollover crash. When the vehicle’s structural integrity is reduced, window glass can break and the doors can open, which can further weaken the roof structure. According to some analysts, a collapsing roof can compromise all the vehicle’s safety features, including its seatbelts, window glazing, side-curtain airbags, and door retention. Partial or complete ejection of the occupants can result. And when a vehicle roof buckles inwards, occupants’ heads are exposed to the risk of head and neck injuries. On September 1, 1973, NHTSA issued its first roof crush stand- ard that took effect for passenger cars. The standard currently ap- plies to passenger cars and multipurpose passenger vehicles, trucks, and buses with a gross weight rating of 6,000 pounds or less. Federal Motor Vehicle Safety Standard 216 establishes a min- imum roof strength standard for these vehicles. The purpose of the standard is to reduce deaths and injuries due to the crushing of the roof into
