Parts and Accessories Necessary for Safe Operation; Saddle-Mount Braking Requirements

Notice of proposed rulemaking; request for comments.
The Federal Motor Carrier Safety Administration (FMCSA) proposes to amend the Federal Motor Carrier Safety Regulations (FMCSRs) by eliminating the requirement for operational brakes on the last saddle-mounted truck or tractor in a triple saddle-mount combination, except when a full mount is present. This is in response to a petition for rulemaking from the Automobile Carriers Conference (ACC) of the American Trucking Associations. Currently, the FMCSRs require operational brakes on any wheel of a saddle-mounted vehicle that is in contact with the roadway. ACC contends that this requirement degrades the braking performance of these combinations because the lightly loaded axle of the last vehicle tends to lock up under heavy braking, and submitted test results supporting this position.
