End Further Info End Preamble Start Supplemental Information


On July 23, 2015, NHTSA published an ANPRM (80 FR 43663) pertaining to a petition for rulemaking from Ms. Marianne Karth and the Truck Safety Coalition (petitioners) regarding possible amendments to the Federal motor vehicle safety standards (FMVSSs) relating to rear impact (underride) guards (FMVSS Nos. 223 and 224). The petitioners requested that NHTSA require underride guards on vehicles not currently required by the FMVSSs to have guards, notably, single unit trucks, and improve the standards' performance requirements for all guards. The ANPRM requested 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.[1] NHTSA provided a 60-day comment period for the ANPRM, which closed September 21, 2015.

Reopening of Comment Period

NHTSA is reopening the comment period for the ANPRM for 30 days.[2] NHTSA believes that a 30 day period is sufficient and balances the interests of encouraging public participation in the rulemaking process with the desire to not unnecessarily delay key decisions by NHTSA about the rulemaking and attainment of the potential societal benefits associated with a final rule.

Accordingly, the public comment closing dates for DOT Docket No. NHTSA-2015-0070 (RIN 2127-AL57) is reopened for 30 days as indicated in the DATES section of this document. NHTSA notes that the 30 day period is in addition to the time that has passed since the original September 21 comment closing date until today. Thus, all in all, more than 30 days has been provided. It is further noted that the agency will consider late comments to the extent possible.

2.  The National Ready Mixed Concrete Association (NRMCA) submitted a comment to the docket requesting a “90-day extension” of the comment period for the ANPRM. The request did not meet NHTSA's requirements for timely submissions of petitions for extension of the time to submit comments (see 49 CFR 553.19). The agency's reopening of the comment period does not result from NRMCA's untimely petition. NHTSA also notes that NRMCA's requested 90 day period is excessively long. NRMCA did not explain why 90 additional days, on top of the 60 days originally provided, are needed to respond to the ANPRM.
