The City of Lynnwood is installing flashing yellow arrow signals at 32 intersections in the city. Installation is expected to be finished by June 2016.
Flashing yellow arrows indicate those turning left should yield to oncoming traffic and pedestrians, but may turn once the way is clear. The flashing yellow signals will replace signs that read “Left Turn Yield on Green” on current signals.
The City of Lynnwood cites a study by the National Cooperative Highway Research Program which found the flashing yellow arrow to be “highly effective at reducing driver confusion.”
The City says flashing yellow arrows are a low-cost measure that creates an opportunity to improve motorist safety at signalized intersections. The Federal Highway Administration has approved the use of flashing yellow arrows for nationwide use.
