ODOT and other jurisdictions across the nation have been fitting selected traffic signals with "Flashing Yellow Arrows".  These new traffic signal displays are designed to help drivers understand when they need to stop, when they have the right-of-way, and when they need to yield to oncoming traffic.   The link above provides a short video courtesy of Washington County that explains a driver's responsibilities at these new signal displays.
