Setting Speed Limits and Right-of-Way

Local speed limits and right-of-way designations in Daly City are established through the municipal code and by traffic control devices installed by the city and county where applicable. Engineering studies, traffic commission actions, or city council ordinances can set posted limits or special rules for particular streets. For legal text, consult the municipal code and the Daly City traffic pages for traffic control policies and notices of changes.Municipal Code[1]

  • Posted limits apply where signs are installed; unposted roads follow state default rules.
  • Right-of-way at uncontrolled intersections follows state law unless a local sign or signal indicates otherwise.
  • Request changes or report signage issues to Daly City Public Works or Police Traffic Division.
Municipal ordinances and traffic devices determine local deviations from default state limits.
