Traffic signs and pavement markings are used to direct and assist motorists in the guidance and navigation tasks required to safely travel on public streets. Traffic Engineering staff determines the need, type, and location of traffic signs and pavement markings. Only standard signs and pavement markings located in the "Manual of Uniform Traffic Control Devices (MUTCD)" are considered for use on City streets.

Signs

Non-standard signs such as "Children at Play" and "Duck Crossing" are not considered for installation. There are three types of traffic signs: Regulatory, Warning, and Guide signs.

Stop sign

Regulatory signs inform roadway users of traffic laws or regulations and include signs such as stop, yield, speed limit, and all signs that are white with black lettering.

Hazard sign

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 motorists 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 obvious conditions tends to breed disrespect for all signs.

 Exit sign

Guide signs give motorists guidance and inform them of intersecting streets, route changes, and other information to help them along their way in the most simple, direct manner possible. Guide signs are green or blue with white lettering.

Pavement Markings

What do the various colors of pavement markings mean?

According to the MUTCD, the colors of longitudinal pavement markings conform to the following basic concepts:

  1. Yellow lines delineate:
    1. The separation of traffic traveling in opposite directions.
    2. The left edge of the roadways of divided and one-way highways and ramps.
    3. The separation of two-way left turn lanes and reversible lanes from other lanes.
  2. White lines delineate:
    1. The separation of traffic flows in the same direction.
    2. The right edge of the roadway.
  3. Red markings delineate roadways that shall not be entered or used.
  4. Blue markings delineate parking spaces for persons with disabilities.
