Section 458.10 - Application

(a) Warning signs are used to warn the highway user of physical or operating conditions on or adjacent to the roadway. Warning signs call for caution on the part of the motorist, pedestrian or snowmobile operator, and generally require a reduction in driving speed for safety.

(b) The use of warning signs should be held to a minimum consistent with the requirements for safety. Unnecessary signs detract from their effectiveness and cause disrespect for all warning signs.
