In an effort to determine the most appropriate legal limits for road vehicles, all the consequences of varying such limits were considered so that an optimum balance could be achieved between the advantages to the community from changing limits and the full cost to the community of providing for these limits. This report presents a review of the existing situation, the evaluation systems prcedures and results, and the recommendations arising from the extensive consideration of the problem. A large number of alternatives which comprised changes to particular limits or combinations of changes to various limits were evaluated and assessed. The potential benefits to be gained through reduced vehicle operating costs, from the use of heavier, longer or higher vehicles were compared with the costs incurred through more rapid deterioration of road pavements and bridges. Consideration was also given to the importance of safety of all road users and environmental factors. Dimension limits (relating to the overall size of vehicles and particular internal dimensions) and mass limits (relating to tire loading, axle loading, axle group and gross vehcile or combination mass) are given.
