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.

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.
