Flashing Yellow Signal
Watch the video below to see how a Flashing Yellow Arrow signal works.
The City of Centerville installed a new Flashing Yellow Arrow sign at the intersection of Spring Valley Road and South Main Street.
“The signal replacement is an effort to reduce crashes and increase driver visibility to lane designation signs and traffic signals,” City Engineer Jim Brinegar said. “The new configuration will also increase signal efficiency and flexibility with the addition of new detection and flashing yellow arrow turn lane signals."
