In another test, position one end of the container so that the fire source is centered 0. This standard specifies requirements for the integrity of compressed natural gas CNGmotor vehicle fuel containers. Position thermocouples so that they are equally spaced over the length of the fire source or length of the container, whichever is shorter.
Initial compliance is required, in accordance with the phase-in schedule, on September 1, This final rule is effective October 24, The performance requirements would ensure that these vehicles provide a sufficient level of survival space to restrained occupants in rollover crashes. This final rule becomes effective September 5, Use a uniform fire source that is 1. 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 establish a safety standard to require automatic forward collision avoidance and mitigation systems on certain heavy vehicles.
It will now end on December 10, In all cases, the Agency’s goal fmvs be to ensure the maintenance of currently required levels of safety performance.

A review of incidents involving natural gas commercial vehicles has also been completed based on data from the Master List of Natural Gas Vehicles Incidents maintained by the Department of Energy and from the National Fire Incident Reporting System.
Motor carriers operating such vehicles in interstate commerce would be required to maintain the speed limiting devices for the service life of the vehicle. The comment period for the RFC was originally scheduled to end on March 5, We believe there is widespread conformance of vehicles to the proposed requirements.

The statutory changes went into effect on October 1,retroactively, and require that FMCSA make conforming changes to its regulations to ensure they are current and consistent with the statutory requirements.
Thompson has not identified a safety need to justify making f,vss he requested, and Mr. ArcelorMittal requests this exemption to allow its employee-drivers to work up to 16 hours per day and be allowed to return to work with less than the mandatory 10 consecutive hours off duty.
NHTSA is denying this petition primarily because the requested force level reduction may set strength levels below an acceptable level for a fmfss environment. The agency believes that requiring V2V communication capability in new light vehicles would facilitate the development and introduction of a number of advanced vehicle safety applications.
Optional early compliance is permitted. The focus of this notice is rules that specifically relate to passenger cars, multipurpose passenger vehicles, trucks, buses, trailers, motorcycles, and motor vehicle equipment.
49 CFR 571.304 – Standard No. 304; Compressed natural gas fuel container integrity.
NHTSA and FMCSA have received requests to extend the comment period for their proposal that would require vehicles with a gross vehicle weight rating tmvss more than fmvds, 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, A single CNG fuel container is not subjected to more than one bonfire test.
