The purpose of a stop sign is to assign right of way at an intersection or where traffic is required to stop. Stop signs are installed at intersections when an engineering evaluation indicates the installation is appropriate. They are installed where:
minor streets enter major streets
streets enter highways
restricted view and accident history indicates a need
Federal and state regulations require the installation of stop signs to follow guidelines in the Manual on Uniform Traffic Control Devices (MUTCD). See the MUTCD website.
