Regulatory Signs

Regulatory signs are used to inform motorists prohibited actions, such as illegal turns, speed limits, and truck information.  Except for the Suggested Speed sign, all regulatory signs are black, and red text on a white circle.  Supplement plaques may be used in conjunction with regulatory signs.  Regulatory signs are grouped into five categories.  To go to a category click one of the following links.
