SEVIERVILLE, Tenn. (WVLT) -- The City of Sevierville has started installing new traffic control technology at selected intersections, designed to prevent accidents and improve traffic flow for vehicles making left turns.

The new left turn signal technology, called “flashing yellow arrow”, incorporates the usual green/yellow/red signal indication colors that motorists recognize on standard traffic signals. Additionally, the flashing yellow arrow indicates that left turns are permitted but must yield to oncoming traffic and pedestrians.
City contractors are in the process of installing the new signals at two intersections on Highway 66: Highway 338 (Douglas Dam Road); and CVS Pharmacy/Buddy’s BBQ. The flashing yellow arrow technology will be present for vehicles traveling both north and south on Highway 66 at these intersections. The new signals should be operational within the next several days.
"These two signals here didn't have a permissive left turn, so we've added the permissive left turn. with the flashing yellow arrow," said Bryon Fortner with Sevierville Public Works. "I think it's more intuitive, people can see the yellow flashing, and they know with a yellow and flashing they can proceed with caution."
A study released in 2007 for the Federal Highway Administration indicated that the flashing yellow arrow helped reduce crashes, improved left turn efficiency, and provided additional traffic management flexibility.
