The owner or operator of any motor vehicle exercising the privilege of parking said vehicle on any street or portion thereof where regulations are in effect restricting the length of time vehicles may be parked does so on the condition that police officers or parking control checkers of the city may place chalk or other removable marks on said vehicle for the purpose of enforcing such parking restrictions.
It is unlawful for any person to erase, rub out, or otherwise remove any chalk or other control measures so placed by a police officer or a parking control checker while the vehicle remains parked on the said street or portion thereof. (Prior code § 25.07.110)
