Our own Hannah Bolton, SDDOT Traffic Engineer, was recently featured in the Winner Advocate newspaper as she worked side-by-side with Winner City staff and the Tripp County ambulance staff to calibrate the white light traffic signal in Winner.
Bolton is a 2014 graduate of Winner High School and graduated from South Dakota School of Mines in 2019 with a degree in civil engineering. She has worked for the SDDOT for nine years and has been a traffic engineer for four years.
“Folks don’t understand why the light is suddenly turning yellow and they speed up to get through the intersection before the light turns red,” Bolton explained. “As always, be alert and proceed with caution through any intersection, but especially if a white light is illuminated.”

What is a white light traffic signal?
A white light sits atop a traffic control signal and resides near the commonly known, stoplight. If the white light is flashing, an emergency vehicle is approaching the intersection from a different direction than you. Slow down and stop until the vehicle passes through the intersection. If the white light is solid, the emergency vehicle is approaching your position in the same direction. Look in your rearview mirror, pull over, and allow the vehicle to pass.
