A vehicle shall not pass along or across the same point on a traffic congested street (designated as such by signs as described in MMC 10.14.040) four or more times in any direction within a two-hour period provided that a police officer has given written notice to whomever is operating the vehicle that has passed the same point the third time that passing said point by said vehicle a fourth time shall constitute a violation of this code. The fact that the operator of the vehicle which has passed the same point the fourth time did not get said written notice shall be no defense to a charge of a violation of this section. (Ord. 4457 §1 (part), 1989).
