Abstract
The Federal Motor Carrier Safety Administration (FMCSA) amends the Federal Motor Carrier Safety Regulations (FMCSRs) to eliminate 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 (ATA), which stated 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.
