TULSA — Officials with the City of Tulsa say they have started to phase in the "Flashing Yellow Arrow" traffic signals at selected intersections on Tuesday.
Officials say the first four intersections with the new flashing yellow arrow are:
- East 46th Street North and U.S. Highway 169
- East 46th Street North and 125th East Avenue
- East 36th Street North and Garnett Road
- West 81st Street South and Olympia Avenue
Officials also say that the intersection of West 71st Street and Tulsa Hills will soon have a flashing yellow arrow signal as well.
The traffic signals with a flashing yellow arrow are for permissive left turns, officials say.
The flashing yellow arrow directs traffic in the left-turn lane, indicating that a driver must yield to oncoming traffic or pedestrians before turning left, the same way the green “ball” indicated previously.
On the new traffic signals, the arrow for the left-turn lane will be either:
- steady red
- steady yellow
- flashing yellow
- or steady green
Officials say “Red” will continue to mean “stop.” Steady yellow will mean “prepare to stop.” Flashing yellow will mean “proceed with left turn after yielding to oncoming traffic or pedestrians;” and green will mean “proceed with left turn.”
The new signals improve traffic flow and safety, officials say. They are most helpful at intersections with traffic congestion, high traffic volumes and above-average accident rates.
Officials say the flashing yellow arrow has been found to be highly effective at reducing driver confusion by the National Cooperative Highway Research Program.
