49CFR FMVSS Bus emergency exits and window retention and release. S1 Scope. This standard establishes requirements for the retention of windows. This responds to your letter asking about the applicability of Federal Motor Vehicle Safety Standard (FMVSS) No. , Bus Emergency Exits and Window. Federal Motor Vehicle Safety Standard (FMVSS) No. , “Bus emergency exits and window retention and release,” applies to buses, including.

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 establish a safety standard to require automatic forward collision avoidance and mitigation systems on certain heavy vehicles. ESC systems in truck tractors and large buses are designed to reduce untripped rollovers and mitigate severe understeer or oversteer conditions that lead to loss of control by using automatic computer-controlled braking and reducing engine torque output.
This document denies a petition for rulemaking, submitted by Ms. Today’s ANPRM requests comment on NHTSA’s estimated cost and benefits of requirements for underride guards on single unit trucks, and for retroreflective material on the rear and sides of the vehicles to improve the conspicuity of the vehicles to other motorists.
Buses with a GVWR of 10, pounds or less shall provide interior release mechanisms that operate by either an upward or pull-type motion. Third, the Agency seeks comment on any additional elements of regulatory relief e.
NHTSA and FMCSA have received requests to extend the comment period for their proposal that would require vehicles with a gross vehicle weight rating of more than 11, Mid-point of the passenger compartment means any point on a vertical transverse plane bisecting the vehicle longitudinal centerline that extends between the two vertical transverse planes which define the foremost and rearmost limits of the passenger compartment.
The force applications for the mechanism s must conform to either S5.
Toyota and the Auto Alliance Alliance. Not more than newtons. NHTSA is denying this petition primarily because the requested force level reduction may set strength levels below an acceptable level for a dynamic environment. One force application shall be applied to each of the two mechanisms to release each mechanism, and another force shall be fmmvss to open the exit. The absence 27 manual driving controls, and thus of a human driver, poses potential barriers fmbss testing, compliance certification and compliance verification.
At least 40 percent of the total required area of unobstructed openings, computed in the above manner, shall be provided on each side of a bus. The effective date of this final rule is September 26, Within the high-force access regions shown in Figures fmvse and 3 for an emergency exit window.
The agency is proposing performance requirements that new large buses of these types must meet in a cmvss in which the vehicle is tipped over from an millimeter mm raised platform onto a level ground surface. Within the low force access regions shown in Figure 3B, in the case of buses whose roof exits are not offset from the plane specified in S5. The force application for the release mechanism must differ by not less than 90 degrees and not more than degrees from the direction of the initial motion to open the exit.
As of March 21,the effective date of the final rule published on December 14, 21 FRdelayed on February 6, 82 FRis further delayed until May 22, The release mechanism shall operate without the use of remote controls or tools, and notwithstanding any failure of the vehicle’s fmgss system. With the lift in the folded or stowed position, such opening is considered a side emergency exit door.
The report also explores technical, legal, security, and privacy issues related to the implementation of V2V. Each release mechanism shall operate without the use of remote controls or tools, and notwithstanding any failure of the vehicle’s power system.
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. Petitions for reconsideration of this final action must be received not later than April 12, The effective date of the final rule published on December 14, 81 FRis delayed until June 5, Summary This fmvzs denies a rulemaking petition submitted by Mr.
The comment period for the RFC was originally scheduled to end on March 5, In the case of windows with one release mechanism, the mechanism shall require two force applications to release the exit.
Separately, NHTSA plans to issue a notice of proposed rulemaking proposing to upgrade the requirements for all guards.
FMVSS & FMVSS – Reflective Solutions
NHTSA believes that V2V capability will not develop absent regulation, because there would not be any immediate safety benefits for consumers who are early cmvss of V2V. Wheelchair securement anchorage means the fvss for transferring wheelchair securement device loads to the vehicle structure. Wheelchair means a wheeled seat frame for the support and conveyance of a physically disabled person, comprising at least a frame, seat, and wheels.
The incorporation by reference of certain publications listed in the standard is approved by the Director of the Federal Register as of February 13, The petitioners request that NHTSA require underride guards on vehicles not currently required by the FMVSSs to have guards, notably, single unit trucks, and improve the standards’ requirements for all guards, including guards now required for heavy trailers and semitrailers.
Restoration of the side marker requirements will have no negative impact on safety or function and will allow motor vehicle manufacturers to avoid unnecessary modifications to their side marker lamps with no added safety or functional benefit. Effective June 14,with optional early compliance as discussed below.
The effective date of this final rule is January 16, For exits with two release mechanisms, there shall be a fmbss of three force applications to open the exit: Performance requirements would apply to side and rear windows, and to glass panels and windows on the roof to fmvsz partial and complete ejection of passengers from these windows and to ensure that emergency exits remain operable after a rollover crash.
Upward from inside the bus and, at the discretion of the manufacturer, from outside the bus. Both of those applications address intersection crashes, which are among the most deadly crashes that U. These comments will aid the Agency in setting research 2117 as well as inform its subsequent actions to lay a path for innovative vehicle designs and technologies that feature ADSs.
49 CFR 571.217 – Standard No. 217; Bus emergency exits and window retention and release.
The data available to the agency shows there is a great deal of uncertainty surrounding the actual gmvss of occupants that may have died due solely to drowning while trapped in an immersed vehicle. The focus of this notification is rules that specifically relate to passenger cars, fmmvss passenger vehicles, trucks, buses, trailers, motorcycles, and motor vehicle equipment. Petitions for reconsideration of this final rule must be received not later than January 30, You should submit comments early enough to ensure that Docket Management receives them not later than July 30, Implementation of the new standard will enable vehicle manufacturers to develop safety applications that employ V2V communications as an input, two of which are estimated to prevent hundreds of thousands of crashes and prevent over one thousand fatalities annually.
For exits with one release mechanism, the exit shall require two force applications to open the exit: Attendees should arrive early enough to enable them to go through security by 9: When the bus configuration precludes installation of an accessible rear exit, a roof exit that meets the requirements of S5.
fmbss As shown in Figure 2 or Figure 3. The focus of this notice is rules that specifically relate to passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, motorcycles, and motor vehicle equipment. 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.
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.
