Matthew Zimmerman got a ticket in February 2010 for driving with steel cleats on his tractor. He drove over newly paved road. He was 13 years old at the time of the citation. His punishment was $500 or 30 days in jail. There was a possibility for both, plus pay for road damages. Matthew (pictured in Des Moines Register) is 15 now and has had the Iowa Supreme Court weigh in on his case.
