Change the first Guidance of MUTCD Section 5C.09, Vehicular Traffic and Nonvehicular Signs (W11 Series and W8-6), to become an Option and amend to read:

Vehicular Traffic signs (see Figure 5C-2) may be used to alert road users to frequent unexpected entries into the roadway by trucks, bicyclists, farm vehicles, fire trucks, and other vehicles. Such signs may be used only at locations where the road user's sight distance is restricted or the activity would be unexpected.
