Notice of Proposed Rulemaking.
FMCSA proposes to amend its Hazardous Materials Safety Permits regulations to incorporate by reference the updated Commercial Vehicle Safety Alliance (CVSA) handbook. The Out-of-Service Criteria provide uniform enforcement tolerances for roadside inspections to enforcement personnel nationwide, including FMCSA's State partners. Currently, the regulations reference the April 1, 2016, edition of the handbook. Through this notice, FMCSA proposes to incorporate by reference the April 1, 2018, edition.
