Abstract

An electrical assembly for a ground vehicle moving along a lane of a road comprises an elevated support, an arm extending transversely across the lane of the road, and a movable portion upon the arm which is moved from a lowered unpowered rest position to a raised powered rest position when a ground vehicle engages the movable portion of the arm. Electrical contacts are spaced from each other so as not to conduct electricity when the movable portion of the arm is disposed at the lowered position and are disposed in contact with each other when the movable portion of the arm is disposed at the raised position.
