This standard specifies performance requirements for the protection of vehicle occupants in crashes. The purpose of this standard is to reduce the number of deaths of vehicle occupants, and the severity of injuries, by specifying vehicle crashworthiness requirements in terms of forces and accelerations measured on anthropomorphic dummies in test crashes, and by specifying equipment requirements for active and passive restraint systems.
In addition, S9, Pressure vessels and explosive devices, applies to vessels designed to contain a pressurized fluid or gas, and to explosive devices, for use in the above types of motor vehicles as part of a system designed to provide protection to occupants in the event of a crash. General requirements. Each passenger car manufactured from January 1, , to August 31, , inclusive, shall meet the requirements of S4. A protection system that meets the requirements of S4.
The vehicle shall meet the crash protection requirements of S5. The vehicle shall - a At each designated seating position have a Type 1 seatbelt assembly or a Type 2 seatbelt assembly with a detachable upper torso portion that conforms to S7. Each passenger car manufactured on or after September 1, , and before September 1, , shall meet the requirements of S4.
The vehicle shall: a At each front outboard designated seating position meet the frontal crash protection requirements of S5. The vehicle shall - a At each designated seating position have a Type 1 seat belt assembly or Type 2 seat belt assembly with a detachable upper torso portion that conforms to S7. The belt assembly shall be either a Type 2 seat belt assembly with a nondetachable shoulder belt that conforms to Standard No. A vehicle shall not be deemed to be in noncompliance with this standard if its manufacturer establishes that it did not have reason to know in the exercise of due care that such vehicle is not in conformity with the requirement of this standard.
A vehicle shall not be deemed to be in noncompliance with this standard if its manufacturer establishes that it did not know in the exercise of due care that such vehicle is not in conformity with this standard. Type 2 seat belt assemblies installed pursuant to this provision shall comply with Standard No.
Type 2 seat belt assemblies installed in compliance with this requirement shall comply with Standard No. The means for detaching the upper torso belt may use a pushbutton action. Each passenger car manufactured on or after September 1, shall comply with the requirement of S4. Each passenger car certified to S14 shall, at each front outboard designated seating position , meet the applicable frontal crash protection requirements of S5.

The vehicle shall be equipped with a dynamic automatic suppression system for the passenger air bag system which meets the requirements specified in S Type 2 seat belt assemblies installed pursuant to this provision shall comply with Standard No. As used in this section, vehicles manufactured for operation by persons with disabilities means vehicles that incorporate a level change device e. An automatic belt that provides only pelvic restraint may not be used pursuant to S4. Each vehicle that is certified as complying with S14 shall, at each front outboard designated regulxtion positionmeet the injury criteria specified in S Additional Documents type regulations. No other restraints are used to hold the vehicle in position during the deceleration of the platform and the departure of the vehicle. Hip circumference sitting The deceleration rate is at least 20g for a minimum of 0. Type 2 seat belt assemblies installed in compliance with this requirement shall conform to Standard No.
The rule requires the vast majority of new heavy truck tractors to achieve a 30 percent reduction in stopping distance compared to currently required levels. For these heavy truck tractors approximately 99 percent of the fleet , the amended standard requires those vehicles to stop in not more than feet when loaded to their gross vehicle weight rating GVWR and tested at a speed of 60 miles per hour mph. For a small number of very heavy severe service tractors, the stopping distance requirement will be feet under these same conditions. Under the special procedures for calculating the fuel economy of those vehicles contained in AMFA, alternative and dual fueled vehicles are assigned a higher fuel economy value for CAFE purposes, which can result in manufacturers earning credits for their fleets. Since the carbon dioxide CO2 emitted from the tailpipes of new motor vehicles is the natural by-product of the combustion of fuel, the increased standards would also address climate change by reducing tailpipe emissions of CO2. Those emissions represent 97 percent of the total greenhouse gas emissions from motor vehicles.
