ISSUES IN TRUCK SIZES AND WEIGHTS--POTENTIAL FOR CONSERVING FUEL THROUGH MODERN TRUCK SIZE AND WEIGHT REGULATIONS

This paper estimates the potential fuel savings which would result from national standards permitting the motor carrier industry to operate in every state at the current Federal truck gross weight limit of 80,000 pounds GVW, and with at least an overall length limit of 65-feet for twin-trailer combinations. Fuel savings is first estimated on a state-by-state basis. However, if 65-foot twins and vehicles having weights of 80,000 pounds are permitted to travel through all states on a nationwide basis, without having to reduce their payloads to conform to restrictive state limits, additional savings will result. If motor carriers are permitted to operate at gross vehicle weights of 80,000 pounds in the six states currently prohibiting weights above 73,280 pounds, an estimated 51 million gallons of diesel fuel will be saved in 1981. If 65-foot twin-trailer combinations are permitted to operate in the 17 states plus the District of Columbia that presently prohibit their use, 93 million gallons of diesel fuel could be saved in 1981. Overall, if both the size and weight restrictive limits were removed, more than 141 million gallons of diesel fuel could be saved. The total savings reflects an adjustment made for double counting. If vehicles weighing 80,000 pounds and 65-foot twin-trailers were premitted on a nationwide basis, 31 million gallons of fuel could be saved. Thus, the total national diesel fuel conservation impact could be 178 million gallons annually. (Author)
