To assist in the direction and control of traffic, to improve safe driving conditions at any intersection or dangerous location and to warm pedestrians or drivers of motor vehicles of dangerous conditions or hazards, the Chief of Police may establish safety zones, lanes of traffic and stop intersections, and he or she may order installation of stop signs, yield signs, warning signs, signals, pavement markings or other devices with the approval of the City Council. No regulation may be established on a trunk highway unless the consent of the Commissioner of Highways is first secured.
