What is the harm of installing an unwarranted traffic sign?
Traffic control devices which include signs, such as stop signs, speed limit signs, animal crossing warning signs and curve warning signs as well as signals and pavement markings, are installed to regulate traffic flow and improve safety. The installation of these traffic control devices should be based on National guidelines; the Manual of Uniform Traffic Control Devices, (MUTCD) gives Traffic Engineers the uniform standards to safely assist motorists as they travel. It defines a series of uniform traffic control devices (signals, signs and pavement markings) which are clear in their messages as applied on the nation’s roadway system. To ensure that the motoring public maintains a healthy respect for traffic control devices, traffic engineers must use them prudently and thereby maximize the safety and efficiency of our streets and highways. It is important to apply traffic control devices consistently, maintaining uniformity in size, shape, color and location so that they command respect and deliver a clear message
