VDOT is implementing new signal displays at some local intersections to make left turns safer and more efficient. The new traffic signals include a "flashing yellow arrow" in place of the solid green ball to allow drivers to turn left after yielding to oncoming traffic.
Since fall 2015, signals with flashing yellow arrows have been installed at the following locations:
- Route 20 at Route 1150 (Mill Creek Drive)
- Route 20 at Piedmont Virginia Community College
- Route 20 at Route 53
- Route 20 at Route 1421 (Elk Drive) / Fontana Drive
- Route 250 at Route 729 (Milton Road)
- Route 250 at Route 22 (Louisa Road)
- Route 250 at the two ramps to Interstate 64
- Route 29 at Gander Drive
- Route 631 (5th Street) at the two ramps to Interstate 64
- Route 631 (Rio Road West) at Route 1403 (Berkmar Drive)
- Route 743 (Hydraulic Road) at Route 852 (Commonwealth Drive)
- Route 1403 (Berkmar Drive) at Route 1417 (Woodbrook Drive)
- Route 1417 (Woodbrook Drive) at Rio Hill Shopping Center
- Route 3 at Route 522
- Route 15/29 at Route 3/522

Why the Flashing Yellow Arrow?
It improves safety. In 2003, the National Cooperative Highway Research Program completed a study that assessed driver understanding of and response to different types of left-turn controls. The study revealed that the flashing yellow arrow was safer and more effective than the more common green ball at conveying the need to yield before turning left. Read more.
It provides operational flexibility. With this type of signal, VDOT can make changes to the order in which different directions of traffic proceed, as well as adjust the timing of the left-turn movement based on traffic volumes during busier times of day. Doing so helps VDOT maximize the flow of traffic.
It is proving successful. In addition to the locations listed above within VDOT's Culpeper District, there are numerous others across the state, including 91 new signals installed in fall 2014 in the Salem and Lynchburg districts.
VDOT has seen local success with crash reduction, such as on the Route 419 corridor in Roanoke County. From April 2009 to April 2013, there were 52 left turn-related crashes at three intersections along Route 419. In the two years following installation of flashing yellow arrow signals, there were only seven left-turn crashes – a considerable safety improvement.
