On March 1, 2021, CVSA submitted comments on the Federal Motor Carrier Safety Administration’s (FMCSA) notice of proposed rulemaking (NPRM) on rear impact guard regulations. The NPRM proposes amending the Federal Motor Carrier Safety Regulations to include rear impact guards in the minimum periodic inspection standards in Appendix G, update the labeling requirements and to exclude road construction controlled horizontal discharge trailers from the rear impact guard requirements. CVSA’s comments support the inclusion of rear impact guards in Appendix G and encourage the agency to act on CVSA’s petition to remove the rear impact guard labeling requirements.
