Book Description

Following the completion of the vehicle weights and dimensions research program in 1986, the implementation planning committee was charged with the responsibility of developing a plan to implement regulatory reform that would result in uniformity in interprovincial truck size and weights in canada. this report lays out the recommended principles and limits which were developed in the context of the following objectives: 1) to encourage the use of the most stable heavy vehicle configurations through the implementation of practical, enforceable weight and dimensions limits, 2) to balance the available capacities of the national highway transportation system by encouraging the use of the most productive vehicle configurations relative to their impact on the infrastructure, and 3) to provide the motor transport industry with the ability to serve markets across canada using safe, productive, nationally acceptable equipment. the recommendations cover all aspects of tractor/trailer size and weight limits, including wheelbase, axle spacing, fifth wheel offset, rear overhang, track width, drawbar length, tire and suspension type, and overall height, width, length and weight. this report is a revised edition of the original draft report issued in june 1986 (irrd 291089).
