Signs & Markings

Federal and State guidelines, detailed in the California Manual on Uniform Traffic Control Devices, dictate the size, shape, and color of all traffic signs and pavement markings. This manual also provides guidelines for installing signs and markings and creates uniformity from state to state.


The City of Stockton Public Works Department Traffic Engineering Division is responsible for studying and approving installations of all the signs and markings within the city of Stockton.



The City is required by State law to comply with the guidelines of the California Manual on Uniform Traffic Control Devices. These policies identify specific traffic and pedestrian volumes, collision history, and any unusual conditions which must be present in the roadway before these traffic control devices may be installed, including stop signs.


Pavement Markings

Lines, symbols, and words are often painted on a roadway to help direct drivers and control traffic flow. Pavement markings are a critical element to guide roadway users and optimize roadway efficiency, both in daylight and at night. 


When you share the public roadways and facilities, you must understand and obey different lines and colors just as you would traffic signs or signals.

  • White and yellow lines along pavement edges and between lanes keep vehicles in line.
  • These lines may be solid or broken (long dashes), single or double. 
  • Unless you are turning, exiting a highway, or changing lanes, always stay between the lines marking your lane.
