“I’ve never heard about this before," Minnihan said. "Nobody I know has ever heard about it." According to the Chicago City Clerk’s office, Sections 9-64-170(a)(3) and (b)(3) of Chicago’s Municipal Code say that a contractor placard is required to be placed on the dashboard for “a contractor who is actually engaged in delivery, service or repair work at a particular address for a particular customer to park their vehicle within a reasonable distance of the address where such work is being performed.” “I don't think it's fair to fine someone for something they don't know they're doing wrong," Minnihan added.
