3. AASHTO on Selecting a Design Vehicle AASHTO specifies 10 class of vehicles The representative design vehicle in each class is larger than and has a larger turning radius than more vehicles in that class For a specific facility the largest design vehicle likely to use the facility with considerable frequency must be taken into account in designing features such as radii at intersections
