(No Parking, Parking Restrictions, Posted Speed Limits, No Right on Red, Drug Free Zones)

Traffic signs can be either regulatory, warning, or guide signs. Regulatory signs, such as STOP, YIELD, or turn restrictions require certain driver actions and can be enforced. Warning signs can provide helpful information, especially to motorists and pedestrians who are unfamiliar with the area. Guide signs provide direction or location information. Examples of signs that may help pedestrians include warning signs for motorists, warning signs for pedestrians, pedestrian push button signs, NO TURN ON RED signs, and guide signs. Advance pedestrian warning signs should be used where pedestrian crossings may not be expected by motorists, especially if there is a high number of motorists who are unfamiliar with the area. A new, brighter fluorescent yellow/green (FYG) color is allowed for use in pedestrian, bicycle, and school warning signs. All signs should be periodically checked to make sure that they are in good condition, free from graffiti, reflective at night, and continue to serve a purpose.

Parking Restrictions

No Parking signs are installed on a street to increase mobility and safety when roads are narrow, used extensively by emergency vehicles, or the curb lane is used as a travel lane. No Parking signs are also placed near an intersection to increase sight distance, thereby decreasing the likelihood of an accident. It is also possible to install No Parking signs that are in effect during peak hours or for special events. No Parking signs on residential streets can be removed when neighbors choose to add parking to their street, if the street is at least 25 wide. Adding parking on both sides of the street narrows the usable and effective street width and causes motorists to drive more slowly.
