Traffic Control Devices

Installing Stop Signs
In order to provide a sound basis for engineering judgment with respect to the need for installing stop signs on all approaches of the roadway, the Department conforms to the Manual on Uniform Traffic Control Devices (MUTCD). This manual, prepared by a national joint committee on municipal, county, and state officials, contains the following conditions or warrants, which should be present before a traffic control device such as a multiway stop control is warranted.
  • As an interim measure where a traffic control signal is warranted and urgently needed;
  • There is evidence of a traffic accident problem indicated by the occurrence of 5 or more reported accidents of a type susceptible to correction by the installation of a multiway stop within a 12-month period; or
  • A significant and evenly distributed volume of vehicular and/or pedestrian traffic is present at the intersection.
It should be noted that "STOP" signs are used to assign right-of-way and are not intended to use just to slow down speeders. Installing stop signs at an unwarranted location can create a false sense of security to the pedestrians and drivers, whereas a disaster may be eminent resulting from a high number of stop sign violations at that location.

Unwarranted signs can also increase the potential of rear-end type accidents. By adhering to the nationally adopted guidelines, we make sure that the stop signs throughout the County are meaningful and necessary but not just a sense of false security.
