The only urgent consideration that has been identified by WisDOT pertains to u-turns under a protected left-turn phase that would conflict with simultaneous or "overlapping" protected right-turn phases. WisDOT is in the process of addressing affected locations on the state highway system with regulatory signing to retain a prohibition on u-turns – but only at these locations. You may have similar concerns regarding implications for locations on county and local roads.
A broader related WisDOT signing policy is being developed, and will be more fully implemented in coming months. Please contact Tom Notbohm, State Traffic Engineer of Design, if you have questions regarding the development of this policy.
