Flashing yellow left-turn arrow installed at Campbell and Primrose intersection



A flashing yellow left-turn arrow is now in place in the eastbound to northbound left-turn lane of the newly improved intersection at Campbell Avenue and Westview Street/Primrose Street.

Traffic engineers consider flashing yellow left-turn arrows safer because they provide a more direct message to drivers to yield to oncoming traffic than solid green circular signals. Flashing yellow arrows decrease traffic delays and are especially effective at intersections with high volumes of traffic.

These types of yield signals are becoming more common in Springfield after a change in federal traffic regulations making the flashing yellow arrow an optional improvement at certain intersections. The Missouri Department of Transportation (MoDOT) installed the first yellow left-turn arrow in Springfield at Kearney Street and Broadway Avenue in 2015. The signal at Campbell and Primrose will be the first installed by Springfield Public Works. Additional flashing yellow arrows are planned for installation at intersections across the city in the near future.

How flashing yellow arrows work

A green left-turn arrow remains in place to allow drivers to make protected left turns from the eastbound-to-northbound direction. When the yellow left-turn arrow begins flashing, drivers must yield to oncoming vehicles and pedestrians. When the yellow arrow stops flashing, drivers should prepare to stop. A solid red arrow means “stop.”

Signs marked “Left Turn Yield on Flashing Arrow” will be displayed next to the left-turn signal to clearly explain its meaning.

For more information, contact Traffic Engineer Tom Dancey at 864-1167.
