"When you get into that work zone, pay attention to the work zone speed limits, put down the cup of coffee or sandwich, put down the cell phone, concentrate on what you're doing. Put both hands on the steering wheel," he said.

Sheriff's deputies who patrol the work zones hope drivers learn to slow down. But a few never get the message.

"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.
