§ 70.23 YIELD RIGHT-OF-WAY STREETS.
   (A)   Any street designated by law as a yield of right-of-way street and so posted is hereby declared to be a yield right-of-way street.
   (B)   The driver of a vehicle in obedience to a yield right-of-way sign shall reduce the speed of his or her vehicle to not more than 20 mph, and shall yield the right-of-way to other vehicles which have entered the intersecting street either from the right or left or which are approaching so closely on such intersection as to constitute a hazard; but said driver having so yielded may proceed at such time as a safe interval occurs.
   (C)   If a driver is involved in a collision at an intersection or interferes with the movement of other vehicles after driving past a yield right-of-way sign, such collision shall be deemed prima facie evidence of the driver’s failure to yield right-of-way.
