Hate to disagree with Virginia Tech’s weed dept., but it looks like birdsfoot trefoil to me.

The blossom looks very much like birdsfoot trefoil, a forage crop I have grown in Wisconsin; and nothing about it looks like the black medic that infested my field before the trefoil became established. BF trefoil is used in Wis.,mostly in mixtures with grasses, for pastures. Thrives on less fertile soils better than alfalfa. It thrives on sides of I-80, along with vetch, in Iowa.
