Statute:
(3) On a road, street, or highway having two or more lanes allowing movement in the same direction, a driver may not continue to operate a motor vehicle in the furthermost left-hand lane if the driver knows or reasonably should know that he or she is being overtaken in that lane from the rear by a motor vehicle traveling at a higher rate of speed. This subsection does not apply to drivers operating a vehicle that is overtaking another vehicle proceeding in the same direction, or is preparing for a left turn at an intersection.
