Federal Motor Vehicle Safety Standards; Occupant Crash Protection; Anthropomorphic Test Devices; Instrumented Lower Legs for 50th Percentile Male and 5th Percentile Female Hybrid III Dummies
On February 3, 2004, NHTSA published a notice in the Federal Register requesting comments on whether to propose adding a high speed frontal offset crash test to Federal Motor Vehicle Safety Standard (FMVSS) No. 208, ``Occupant crash protection.'' The notice informed the public about recent testing the agency conducted to assess the benefits and/or disbenefits of such an approach. Based on our analysis of those comments, and other information gathered by the agency, we have decided to withdraw the rulemaking proceeding to amend FMVSS No. 208 to include a high speed frontal offset crash test requirement. Additional research and data analyses are needed to make an informed decision on rulemaking in this area. Additionally, we have decided to withdraw the related rulemaking proceeding to amend part 572 to include lower leg instrumentation until further testing necessary for federalization is completed.
Federal Motor Vehicle Safety Standards; Roof Crush Resistance
As part of a comprehensive plan for reducing the serious risk of rollover crashes and the risk of death and serious injury in those crashes, this document proposes to upgrade the agency's safety standard on roof crush resistance in several ways. First, we are proposing to extend the application of the standard to vehicles with a Gross Vehicle Weight Rating (GVWR) of 4,536 kilograms (10,000 pounds) or less. Second, we are proposing to increase the applied force to 2.5 times each vehicle's unloaded weight, and to eliminate an existing limit on the force applied to passenger cars. Third, we are proposing to replace the current limit on the amount of roof crush with a new requirement for maintenance of enough headroom to accommodate a mid-size adult male occupant. Because the impacts of this rulemaking would affect and be affected by other aspects of the comprehensive effort to reduce rollover-related injuries and fatalities, we are also seeking comments on some of those other aspects.
Notice of Technical Workshop and Demonstration-Wednesday, September 21, 2005
This notice announces that NHTSA will hold a compliance test program workshop to discuss and demonstrate the Office of Vehicle Safety Compliance (OVSC) Laboratory Test Procedure (TP) for the agency's safety standard for tire pressure monitoring systems (TPMS). Vehicle manufacturers, tier-one TPMS suppliers, TPMS component manufacturers, and other interested persons with technical knowledge of TPMS who wish to participate in the workshop are asked to pre-register and are invited to submit related technical issues for discussion at the meeting.
