Every agency that owns road signs is required by the FHWA to develop a sign management plan and ensure that regulatory and warning signs meet retroreflectivity standards from the Manual on Uniform Traffic Control Devices. The Minnesota LRRB and MnDOT have updated the Minnesota’s Best Practices for Traffic Sign Maintenance/Management Handbook to include the current sign retroreflectivity requirements, updated information about expected sign life and typical sign maintenance budgets, and documentation of successes achieved by townships in removing signs. The handbook is intended to provide local governments with guidance about recommended sign maintenance methods that will help them meet FHWA’s adopted retroreflectivity performance measures and implementation deadlines.
