Montgomery County - Stop Sign Monitoring Systems Pilot Program - Gaithersburg and Rockville MC 5-26
HB 601 authorizes the use of stop sign monitoring systems in school zones within the City of Gaithersburg and the City of Rockville, expanding a pilot program previously allowed in Prince George’s County, Baltimore City, and Takoma Park. The bill requires local governments to approve these systems through local law after public hearings and mandates clear signage and public notice before implementation. It specifically limits the systems to school zones on local highways (for cities) or state highways (for the State Highway Administration), and defines "violation" as failing to stop completely at a stop sign. The policy change directly affects drivers navigating stop signs in school zones within these two cities during the pilot period.
