A foldable windshield assembly comprises upper and lower pillar supports, upper and lower windshield members connected thereto, and a hinge disposed between the upper and lower pillar supports. The hinge comprises a first connector rigidly connected to one pillar support, a second connector slidably connected within the other pillar support, and a pivot member pivotally connected to one of the connectors by a pivot connector defining a pivot axis and rigidly connected to the other of the connectors, the pivot member received within a pillar support associated with the second connector. The pivot axis intersects one of the pillar supports to maintain the upper windshield member in a use position, and the upper windshield member is moveable between use and folded positions by separating the upper pillar from the lower pillar to reveal the pivot connector and folding the upper windshield member over the lower windshield member.
