"I've actually heard officers that have contacted the court to advise them that the client was going to be late because they were receiving another citation," said Winnebago County Sheriff's Deputy Tom Makurat.
And the Melhorn and Neumeyer families say when you drive through construction zones remember what high speeds and reckless driving have cost them
