Wisconsin State Law permits U-turns at controlled intersections unless signs are installed to indicate the maneuver is prohibited. U-turns will have to be made from the left-most turn lane in the same fashion as a conventional left turn. Vehicles on the intersecting street attempting to turn right on red must yield to the U-turning vehicle. Backing up is not allowed in a U-turn, so drivers will have to be familiar with their vehicle’s turning radius. U-turns will also be prohibited on curves and hill crests where visibility is less than 500 feet.
