The driver of a vehicle, intending to turn left within an intersection or into an alley, private road, or driveway shall yield the right-of-way to any vehicle approaching from the opposite direction if it is so close as to constitute a hazard. At intersections controlled by traffic lights with separate left-turn signals, any vehicle making a left turn when so indicated by the signal shall have the right-of-way over all other vehicles approaching the intersection.
