The Federal Motor Carrier Safety Administration has amended the Federal Motor Carrier Safety Regulations 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.

FMCSA said its amended rule is in response to a petition for rulemaking from the Automobile Carriers Conference of the American Trucking Associations, 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.
