Petitions for reconsideration of this final rule must be received not later than August 7, The initial compliance date is September 1,with full phase in by September 1, A bus equipped with emergency exit windows shall have an even number of such windows, not counting the push-out rear window required by S5.

This standard establishes requirements for the retention of windows other than windshields in busesand establishes operating forces, opening dimensions, and markings for bus emergency exits.

This final rule is effective on November 9, Public comments are welcome at this meeting, but all should be oral, and any supporting presentations or materials should be submitted to the docket for consideration.

Optional early compliance is permitted.

The agency requests comments on this alternative strategy and other potential enhancements to the current body block test procedure. After a careful technical review of the petition and the issues raised by the petitioner, the agency has decided to grant the petition because there is sufficient evidence to indicate that a larger lane width is needed for testing of long wheelbase truck tractors.

NHTSA is planning on issuing two separate notices—an advanced notice of proposed rulemaking pertaining to rear impact guards and other safety strategies for single unit trucks, and a notice of proposed rulemaking focusing on rear impact guards on trailers and semitrailers.

FMVSS & FMVSS – Reflective Solutions

As of March 21,the effective date of the final rule published on December 14, 81 FRdelayed on February 6, 82 FRis further delayed until May 22, School buses shall meet the requirements of S5. Attendees should arrive early enough to enable them to go through security by 9: Continued high levels of motorcycle related fatalities, the ongoing use of novelty helmets by motorcyclists and the poor performance of these helmets in tests and crashes have prompted the agency to clarify the status of such helmets under federal law to ensure that all relevant legal requirements are readily enforceable.


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. The purpose of this standard is to minimize the likelihood of occupants being thrown from the bus and to provide a means of readily accessible emergency egress.

FMVSS 131 & FMVSS 217

The compliance date is September 1,with full phase in by September 1, Third, the Agency seeks comment on any additional elements of regulatory relief e. His petition includes two requests: Marianne Karth and the Truck Safety Coalition Petitioners requesting that the agency improve the safety of rear impact underride guards on trailers and single unit trucks.

2217 believe there is widespread conformance of vehicles to the proposed requirements. By mandating V2V technology in all new vehicles, but not requiring specific safety applications, it is NHTSA’s belief that such capability will in turn facilitate market-driven development and introduction of a variety of safety applications, as well as mobility and environment-related applications that can potentially save drivers both vmvss and fuel.

Petitions for reconsideration of this final rule must be fmvsw by December 27, For exits with one release mechanism, the exit shall require two force applications to open the exit: The comment period for the RFC was originally scheduled to end on March 5, The effective date of the final rule published on December 14, 81 FRis delayed until September 5, Initial compliance is required, in accordance with the phase-in schedule, on September 1, You should submit comments early enough to ensure that Docket Management receives them not later than July 30, For emergency exit doors, the designation shall be located at the top of, or directly above, the emergency exit door on both the inside and outside surfaces of the bus.

The documents referenced in gmvss notification will be available in the docket as of April 16, NHTSA seeks comment on the research report, and solicits additional information, data, and analysis that will aid the agency in developing an effective proposal to require new light vehicles to be V2V-capable.


For several years, NHTSA has researched forward collision avoidance and mitigation technology on heavy vehicles, including forward collision warning mfvss automatic emergency braking systems.

Fmss for reconsideration of this final rule must be received not later than November 13, In the case of windows with one release mechanism, the mechanism shall require two force applications to release the fmvs. The Agency also seeks comments from road users, including vehicle drivers and passengers, cyclists and pedestrians. However, in determining the total unobstructed openings provided by a busno emergency exit, regardless of its area, shall be credited with more than 3, square centimeters of the total area requirement.

Wheelchair securement anchorage means the provision for transferring wheelchair securement device loads to the vehicle structure. School buses shall not be equipped with horizontally-sliding emergency exit windows.

In the case of a bus equipped with three side emergency door exits pursuant to Table cmvss, the third shall be located on the left side of the bus. Summary This document grants the petition for rulemaking submitted by the Truck Safety Coalition, the Center for Auto Safety, Advocates for Highway and Auto Safety, and Road Safe America on February 19,to fmvs a safety standard to require automatic forward collision avoidance and fmvsw systems on certain heavy vehicles.

The absence of manual driving controls, and thus of a human driver, poses potential barriers to testing, compliance certification and compliance verification. Earlier, NHTSA published an advanced notice of proposed rulemaking requesting comment on strategies pertaining to underride protection afforded by single unit trucks.

The data available to the agency shows there is a great deal of uncertainty surrounding the actual number of occupants that may have died due solely to ffmvss while trapped in an immersed vehicle. For exits with two release mechanisms, there shall be a total of three force applications to open the exit: Therefore, the agency grants the Petitioners’ request to initiate rulemaking on rear impact guards.

The effective date of this final rule is January 16, The effective date of this rule is August 24,
