• Abstract:
  Permissive left turns, where a driver does not have a green arrow and must wait for a gap in oncoming traffic before turning, can be indicated by different traffic signal configurations. Flashing yellow arrows are becoming a preferred signal type in Minnesota and across the nation. New research provides traffic engineers with confidence that drivers understand the meaning of the signal, even without an accompanying Left Turn Yield sign.
