(A) The driver of a vehicle who approaches an intersection where traffic is controlled by traffic-control signals shall do all of the following, if the signal facing the driver either exhibits no colored lights or colored lighted arrows or exhibits a combination of such lights or arrows that fails to clearly indicate the assignment of right-of-way:
(1) Stop at a clearly marked stop line, but if none, stop before entering the crosswalk on the near side of the intersection, or, if none, stop before entering the intersection;
(2) Yield the right-of-way to all vehicles in the intersection or approaching on an intersecting road, if the vehicles will constitute an immediate hazard during the time the driver is moving across or within the intersection or junction of roadways;
(3) Exercise ordinary care while proceeding through the intersection.
(B) Except as otherwise provided in this division, whoever violates this section is guilty of a minor misdemeanor. If, within one year of the offense, the offender previously has been convicted of or pleaded guilty to one predicate motor vehicle or traffic offense, whoever violates this section is guilty of a misdemeanor of the fourth degree. If, within one year of the offense, the offender previously has been convicted of 2 or more predicate motor vehicle or traffic offenses, whoever violates this section is guilty of a misdemeanor of the third degree.
