218 49 CFR Part 571. Motorcycle Helmets

A notice of proposed rulemaking (NPRM) amending FMVSS No. 218 was published on May 21, 2015 (80 FR 29458). The NPRM set forth an interpretation of the definition of “motor vehicle equipment” in the United States Code, as amended by the Moving Ahead for Progress in the 21st Century (MAP–21) Act, and requested comments on two proposed changes to the motorcycle helmet safety standard, FMVSS No. 218. NHTSA proposed to add a definition of “motorcycle helmet” and modify the existing performance requirements of the standard by adding a set of dimensional and compression requirements. These requirements and the associated test procedures would identify those helmets whose physical characteristics indicate that they likely cannot meet the existing performance requirements of the standard. Third, NTHSA proposed an optional alternative compliance process for manufacturers whose helmets do not comply with the proposed dimensional and compression requirements, but do comply with the performance requirements and all other aspects of FMVSS No. 218 . If this proposal is adopted, NHTSA will publish a list of helmets that have complied with the alternative compliance process and can therefore be certified by their manufacturers. The NPRM was the result of the agency’s assessment of other actions that could be taken to further increase the percentage of motorcyclists who wear helmets that comply with the helmet standard.

Preliminary Economic Assessment
Nissan North America, Inc. Petition for Exemption from Two-Fleet Rule Affecting Compliance with Passenger Automobile Fuel Economy Standards

Nissan filed a petition requesting exemption from the two fleet rule for the 2006-2010 model years. The two fleet rule, which is contained in the CAFE statute, requires that a manufacturer divide its passenger automobiles into two fleets, a domestically-manufactured fleet and a non-domestically manufactured fleet, and ensure that each fleet separately meets the CAFE standards for passenger automobiles. The CAFE statute requires NHTSA to grant such a petition unless it finds that doing so would result in reduced employment in the U.S. related to motor vehicle manufacturing. NHTSA’s analysis does not support a finding that granting the petition would reduce automotive manufacturing employment in the United States. Accordingly, in this notice, NHTSA is granting Nissan’s petition.

Preliminary Regulatory Impact Analysis
111 NPRM to Require a Rear Detection System for Single-Unit Trucks

The agency estimates that approximately 79 fatalities per year (13 on-road and 66 off-road) and 148 injuries per year are attributable to straight trucks backing up. The agency believes that requiring a rear detection system will reduce the number of fatalities, injuries, and property damage crashes by giving truck operators the ability to detect objects behind the truck. In this analysis, we examine two possible counter-measures: a cross-view mirror system and a camera system.

Preliminary Regulatory Evaluation
49 CFR Parts 571, 585, 586, 589, 590, 596, 597 Occupant Crash Protection

This document adopts NHTSA’s proposal to require all designated seating positions in rear seats, other than side-facing seats, be equipped with Type 2 integral lap/shoulder safety belts. Side-facing seats may be equipped with either a Type 1 lap belt or a Type 2 belt. This final rule responds to a Congressional mandate that the agency begin to phase-in requirements for lap/shoulder belts for all rear seating positions, wherever practicable, not later than September 1, 2005.

Final rule
208 49 CFR Part 552, 571, 585, 595 Occupant Crash Protection

The agency is proposing to upgrade the agency's occupant protection standard to require advanced air bags.
