Regulatory Signs
Regulatory traffic signs are intended to inform road users of selected laws or regulations required for driving on the road. Signs indicating these requirements should be designed and installed in areas along the roadway that provide adequate visibility, reflectivity, and be legible according to the federal guidelines. These types of signs can be found on the streets, parking lots, public parks, beaches or in architectural facilities prohibiting specific types of activities, either at all times or at specified times. The disregard of regulatory signs may constitute a violation. Regulatory signs must be retroreflective or illuminated to show the same shape and color, day or night, unless otherwise specified.
Some examples of Regulatory signs include:
Traffic signals, rights of way and pedestrian crosswalks
Speed limits and enforcement areas
Lane control, movement prohibition, passing and slow traffic lanes
Selective exclusion, one way and divided highways
Road features such as roundabout, closed roads, or headlight use
Weight limits and defined truck routes
Parking, standing and stopping signs
