Mobridge Signal Using Flashing Yellow Arrow

MOBRIDGE, S.D. – (SD State News) The South Dakota Department of Transportation is advising motorists that newly installed traffic lights at the intersection of Highway 12 and Main Street in Mobridge are using the flashing yellow arrow as part of the signal system.

A flashing yellow arrow means left turns are permitted, but drivers must first yield to oncoming traffic and pedestrians before proceeding with caution. The system replaces the solid green “ball” indication as a signal for motorists to proceed through an intersection.

The solid yellow arrow means motorists should prepare to stop or complete left turns if already in the intersection.

The change to flashing yellow arrows is the result of a national study done for the Federal Highway Administration which demonstrated that the new signals help reduce left turn crashes by 35 percent.
