Traffic signs and pavement markings are used to direct and assist vehicle operators in the guidance and navigation tasks required to safely traverse public streets. Traffic Engineering Staff determines the need, type, and location of traffic signs and pavement markings. There are 3 types of traffic signs, Regulatory Signs, Warning Signs, and Guide Signs. Regulatory Signs inform roadway users of traffic laws or regulations and include signs such as Stop signs, Yield signs, speed limit signs, and all signs that are white with black lettering. Warning Signs are used to warn motorists of existing or potentially hazardous conditions on or adjacent to a street or highway.
Warning signs are yellow with black lettering.
Adequate warnings are of great assistance to the vehicle operator and are valuable in safeguarding and expediting traffic. The use of warning signs is kept to a minimum because the unnecessary use of them to warn of conditions, which are apparent, tends to breed disrespect for all signs. Guide Signs are placed to give the motoring public guidance and to inform them of intersecting streets, route changes, and other information to help motorists along their way in the most simple, direct manner possible. Guide signs are green or blue with black lettering.
