The stability and control characteristics of heavy-duty truck combinations used in Canada were determined as an aid for the development of new regulations on the weights and dimensions of vehicles in interprovincial trucking. The results serve to classify the contrasting dynamic performance qualities of some 22 vehicle configurations, distinguished by number and placement of axles, number of trailers, and type of hitching mechanisms. Novel measures of performance were developed for characterizing (1) the dynamic stability of roll-coupled trailer combinations and the offtracking overshoot in a rapid path-change maneuver, and (2) the potential for low-speed jackknife while towing a trailer with multiple-wide-spread axles around a tight turn. Generalized performance evaluation techniques are outlined for future use in examining prospective new vehicle combinations.
