To ensure that posted "Deer Warning" signs maintain the respect of the road user, Montgomery County Department of Transportation only posts such warning signs at locations where there has been a history of documented deer/auto collisions, and where the posted speed limit is 35 mph or greater.

If the road is a numbered route such as MD 355 (Rockville Pike), MD 117 (Clopper Road), please contact the Maryland Department of Transportation State Highway Administration at 301.513.7300.
