Stop Signs Why doesn't the City of Warwick install more stop signs, particularly at 4-way intersections, to reduce speeding and crashes? What are the Official guidelines that determine when a stop sign is warranted? When are stop signs used? What are the specific criteria for installing stop signs? What are the specific criteria for installing all-way stops? How does the City of Warwick know whether or not a particular intersection meets the MUTCD warrants? What are the "rules of the road" at Warwick Intersections where multi-way stop signs have been installed in accordance with MUTCD warrants? Shouldn't the City of Warwick be allowed to install stop signs where and when it wants, particularly when requested by a neighborhood? Where can I read more information and research stop signs?
