Over the summer, there are all kinds of highway work zones across the Tri-State area.
They're easily marked and identified.
But what about the temporary - rolling work zones?
State police in Illinois, Missouri and Iowa want you to slow down as you approach those.
But h ow many times have you driven into a highway work zone and have seen the proper cones, lights and signage ... and then temporary rolling work zones when all there is, is a flashing arrow on top of a truck telling you to merge.
Mike Kindhart is a trooper with the Illinois State Police and he said, "w hen you have the moving zones, such as the stripping, the painting and the things going on on the interstate. At that time we've got to use more common sense. We've got to slow down and reduce our speed. It's not marked, it's a lane change to be adjacent to the vehicles that are there in the construction zone or in that moving zone. And at that time, we have to proceed with caution."
In 2009, 53 people were killed in Illinois, Missouri and Iowa highway work zone crashes. And many times it was due to speed and inattention. But the state police say when you come onto a temporary work zone, you need to treat the vehicles just like you would if it was a police car or fire engine.
" And with that moving zone like that as I said, it's not fully marked down to 45 miles per hour, but it is still covered in what we call the Scott's Law," said Kindhart.
Although there isn't a specific law targeting drivers who speed past through a rolling work zone, that doesn't prevent police officers from patrolling those areas looking for unsafe drivers.
Remember if you're caught speeding through a work zone or talking on a cell phone while travelling through a highway construction zone, you face substantial fines in almost every state in the U.S.
