Stop Sign Guidelines
Because the stop sign causes a substantial inconvenience to motorists, it should be used only where warranted. A stop sign may be warranted at an intersection where 1 or more of the following conditions exist:
- Intersection of a less important road with a main road where application of the normal right-of-way rule is unduly hazardous
- Street entering a through highway or street
- Unsignalized intersection in a signalized area
- Other intersections where a combination of high speed, restricted view and serious accidents indicate a need for control by the stop sign
When to use and not use stop signs:
Traffic Signal Guidelines
- Stop signs should never be used on the through roadways of expressways.
- Stop signs shall not be erected at intersections where traffic control signals are operating.
- Where 2 main highways intersect, the stop sign of signs should normally be posted on the minor street to stop the lesser flow of traffic.
- Stop signs may be used at selected railroad-highway grade crossings only after their need has been determined by a detailed traffic engineering study.
- Portable or part-time stop signs shall not be used except for emergency purposes.
- Stop signs should not be used for speed control.
Traffic control signals should not be installed unless 1 or more of the signal warrants in the U.S. DOT Manual on Uniform Traffic Control Devices (MUTCD) are met. The satisfaction of a warrant or warrants is not in itself justification for a signal.
