Expect to see workers in those bucket trucks at four intersections in the next couple of weeks along Electric Road in Roanoke County.
VDOT is adding the "blinking yellow arrow" traffic signal to left hand turns on Electric at Chaparall, Colonial, Postal, and Springwood Park Drive near Ruby Tuesday restaurant.
The blinking yellow arrows basically replace the old full yellow circular traffic signals, meaning it's okay to go as long as you yield to on-coming traffic.
The red and green arrows mean the same.
The solid yellow arrow, that doesn't blink, means the light is about to change.
The system is already up and working at Electric and Colonial.
VDOT says it makes the intersections safer since drivers tend to be more alert when they see the blinking yellow arrow.
