Advisory Speeds
Advisory speeds are the desirable speeds for curves, intersections, or other locations where design standards or physical conditions of the roadway restrict safe operating speeds to values less than the maximum legal speeds or posted regulatory speed limit. Figure 2-1 illustrates the use and application of warning signs with advisory speeds. For additional information on determining advisory speeds, see
