This final rule is effective on November 9, The agency proposed these changes and, after a review of the comments received, has determined that these two revisions are appropriate and will not result in any degradation of motor vehicle safety. Fmvsx effective date of this final rule is November 29, Global Automakers petitioned the agency for reconsideration, seeking to correct what it believes is an error in formula for determining the number of designated seating positions in longer seating positions.


The potential effectiveness of such a tool to successfully aid an occupant’s safe exit from an immersed vehicle is also not known. ANSI is also involved in setting standards for alternative vehicle technology in particular.

The impactor and impact speed would simulate the loading from an average size unrestrained adult male impacting a window on the opposite side of a large bus in a rollover. This final rule increases harmonization with existing requirements in European regulations. Today’s proposal would facilitate the introduction of new technologies including hydrogen fuel cell vehicles and 48 volt mild hybrid technologies, and responds not only to GTR No.

This document reopens the comment period for a notice of proposed rulemaking NPRM published January 28, There are standards, regulations and guidelines for vehicle design and manufacture from a variety of government and industry sources.

Based on the agencies’ review of the available data, limiting the speed of these heavy vehicles would reduce the severity of crashes involving these vehicles and reduce the resulting fatalities and injuries.

His petition includes two requests: Without a mandate to require and standardize V2V communications, the agency believes that manufacturers will not be able to move forward in an efficient way and that a critical mass of equipped vehicles would take many years to develop, if ever.

Performance requirements would apply to side and rear windows, and to glass panels and windows on the roof to mitigate partial and complete ejection of passengers from these windows and to ensure that emergency exits remain operable after a rollover crash.

Hofferberth on April 1, This document is the result of the agency’s assessment of other actions that could be taken to increase further the percentage of motorcyclists who wear helmets that comply with the helmet standard.

ADS testing and development are already underway in several areas of the United States. For several years, NHTSA has researched forward collision avoidance and mitigation technology on heavy vehicles, including forward collision warning and automatic emergency braking systems. You should submit your comments to ensure that Docket Management receives them not later than July 20, NHTSA is still evaluating the Petitioners’ request to improve side guards and front override guards and will issue a separate decision on those aspects of the petition at a later date.

When the vehicle is impacted from the rear by a barrier moving at any speed up to and including 30 mph, with test dummies as specified in part of this chapter at each front outboard designated seating positionunder the applicable conditions of S7, the fuel pressure drop shall not exceed the limits of S5.

We also request comments on ways to make these regulations easier to read and understand. Thompson has not identified a safety need to justify making changes he requested, and Mr.
