Hard to tell without a view of the head, but the markings look like a Northern Brownsnake or a Northern Pinesnake.
The Northern Brown is found everywhere in MD. The Pinesnake is much more rare. I think a few counties on the eastern shore and a few in Anne Arundel county.
Neither are venomous.
Might want to send that pic to DNR. They are VERY interested in knowing where the Pinesnakes are found.
