Parts and Accessories Necessary for Safe Operation; Inspection, Repair, and Maintenance; General Amendments

Summary: FMCSA amends the Federal Motor Carrier Safety Regulations (FMCSRs) in response to several petitions for rulemaking from the Commercial Vehicle Safety Alliance (CVSA) and the American Trucking Associations (ATA), and two safety recommendations from the National Transportation Safety Board (NTSB). Specifically, the Agency adds a definition of ``major tread groove'' and an illustration to indicate the location of tread wear indicators or wear bars on a tire signifying a major tread groove; revises the rear license plate lamp requirement to eliminate the requirement for an operable rear license plate lamp on vehicles when there is no rear license plate present; amends the regulations regarding tires to prohibit the operation of a vehicle with speed-restricted tires at speeds that exceed the rated limit of the tire; provides specific requirements regarding when violations or defects noted on an inspection report must be corrected; amends two appendixes to the FMCSRs to include provisions for the inspection of antilock braking systems (ABS) and automatic brake adjusters, speed- restricted tires, and motorcoach passenger seat mounting anchorages; amends the periodic inspection rules to eliminate the option for a motor carrier to satisfy the annual inspection requirement through a violation-free roadside inspection; and amends the inspector qualification requirements as a result of the amendments to the periodic inspection rules. In addition, the Agency eliminates introductory regulatory text from an appendix to the FMCSRs because the discussion of the differences between the North American Standard Inspection out-of-service criteria and FMCSA's periodic inspection criteria is unnecessary.
