Stop Signs
Stop signs installed in the wrong places for the wrong purposes usually create more problems than they solve. One common misuse of stop signs is to arbitrarily interrupt traffic, either by causing it to stop or by causing such an inconvenience that motorists are forced to use other routes. Studies conducted in many parts of the country show that there is a high incidence of intentional violations where stop signs are installed as "nuisances" or "speed breakers." These studies show that speed was only reduced in the immediate vicinity (about 100 to 150 feet) of the "nuisance" stop signs. But, speeds were actually higher between stop signs than they would have been if these signs had not been installed.
These same studies show that drivers increase their speeds between unwarranted stop signs to make up for the lost time. Because of these studies and the increased speeds of drivers on streets with unwarranted stop signs, the Michigan Manual of Uniform Traffic Control Devices clearly states that "Stop signs should not be used for speed control." At the right place and under the right conditions, a stop sign tells drivers and pedestrians who has the right of way.
Nationally recognized standards have been established to determine when stop signs should be used. These standards, or "warrants," are:

National Standards
Nationally recognized standards have been established to determine when stop signs should be used. These standards, or "warrants," are:
- Intersections of a less important road with a main road where the normal right of way rule is unduly hazardous
- A street entering a through highway or street
- Unsignalized intersections in a signalized area
- Other intersections where a combination of high speed, restricted view and serious crash record indicates a need for control by the stop sign
