Truck operations have a pronounced effect on the design of highways. Various characteristics of trucks are reflected in the standards used today for planning, designing, and operating highways. In determining geometry, the type, size, weight, gradability, acceleration, deceleration, and turning features of trucks all play an important part. These are accounted for by a classification of design vehicles that are represented by the largest trucks and their most imposing characteristics of operation. In the design process, one class of vehicles is selected for a particular type of highway or set of conditions. The application of standards, which reflect design vehicle performance, generally produces appropriate results. There are a few areas in which operational aspects of trucks may be further considered. Also, the more recent introduction of "extra" large trucks not yet included in national geometric highway standards for certain conditions should be addressed. The features and adequacy of present standards are reviewed and areas in which reinforcement or inclusion of additional standards or concerns is needed are highlighted.
