In 1988 the American Association of State Highway and Transportation Officials (AASHTO) asked the Transportation Research Board (TRB) to evaluate a proposal for a new approach to regulating the sizes and weights of trucks using U.S. roads. Truck operators would gain productivity through higher allowable gross weights, but would add enough extra axles to their vehicles to reduce the load carried by each one. This approach to size and weight regulation was advocated in an address to the December 1984 AASHTO Annual Meeting by former Federal Highway Administrator Francis C. Turner, and has come to be known as the Turner Proposal. This article describes the original proposal, defines the prototype Turner trucks that the committee evaluated, and finally lists some questions about the equipment that the committee asked industry to answer.
