Residents may request deployment of a Montgomery County Department of Transportation (MCDOT) Dynamic Speed Sign (DSS) to inform motorists of the actual speed at which they are traveling on neighborhood streets. MCDOT will deploy these units on Neighborhood Connectors, Neighborhood Streets and occasionally on other two-lane non-Neighborhood Streets, upon request. The units are installed along the roadway for a period of up to five (5) days, typically Monday through Friday. When possible, the trailer mounted units will be placed facing one direction on Monday, then rotated to face the opposite direction on Wednesday, prior to removal on Friday. Requests for redeployment of the unit at a location may be made after three months. MCDOT will accommodate redeployment requests as scheduling allows. It is MCDOT practice to refrain from the deployment of the units on weekends, holidays, including the timeframe from December 15th through January 2nd. If the road is a numbered route such as MD 355 (Rockville Pike) or MD 117 (Clopper Road), please contact Maryland Department of Transportation State Highway Administration at 301.513.7300.
