If you think you've been seeing flashing yellow arrows on traffic signals around town, chances are you have.

The Illinois Department of Transportation has installed the flashing yellow lights at 12 intersections across Peoria.

The flashing yellow arrow means drivers can turn left after yielding to oncoming traffic and pedestrians.

They say studies have been done across the country to identify the best way to communicate this to drivers and the flashing yellow arrow is most widely understood.

"Tests have shown there has been a big decrease in left turn crashes once you go to this flashing yellow arrow," said Randy Laninga, an IDOT Operations Traffic Engineer. "Most show a 30-percent reduction in left turn crashes."

They will be installing the lights at two intersection on War Memorial Drive Friday. Crews will be at the Mountello Drive intersection from 8:30 to noon and the Grand Boulevard intersection from noon to 3:30.

They will have 100 intersections outfitted with the new yellow lights by spring.

A civil engineering class at Bradley will monitor their effectiveness.
