DENVER (CBS4)- Denver Public Works hopes a new type of turn signal will help keep traffic moving.

The flashing yellow light signals drivers to turn left through intersections when there is no oncoming traffic.

The signal at Central Park Boulevard and Interstate 70 will flash a yellow arrow. It signals drivers to turn left through intersections when there is no oncoming traffic.

It’s the first in Denver with the new display.

“The flashing yellow arrow will allow people to turn left when there is no oncoming traffic, therefore alleviating congestion and helping more cars get through the intersection,” said Denver Public Works spokeswoman Amy Wrens.

Seven of the turn signals are planned for the City of Denver. Those intersections include Speer and Wewatta, Dartmouth and Sheridan, Hampden and Tamarac, Federal and I-70 and Green Valley Ranch and Pena Blvd.

There are already flashing yellow lights at some intersections in Boulder and Aurora.
