Stop Signs & Traffic Signals

Each year, the Traffic Engineering Division receives many inquiries about installing stop signs or traffic signals as a way to reduce speeding. However, research shows that other measures are often more effective than adding more stop signs or traffic signals. The purpose of stop signs and traffic signals is to assign right of way at an intersection, not to control speeding.

Public understanding of the function of stop signs and traffic signals is one of the most important elements in reducing speeding and traffic accidents. The following information explains our policies on intersection traffic controls and the correct use of stop signs and traffic signals.
