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 enforcement personnel nationwide, including FMCSA's State partners, with uniform enforcement tolerances for roadside inspections. Currently, the regulations reference the April 1, 2018, edition of the handbook. Through this document, FMCSA proposes to incorporate by reference the April 1, 2019, edition.
