If you need evidence of why it's important to move over when seeing a squad car or ambulance at the side of the highway, watch this video from the State Patrol.
It happened on Friday morning on I-43 in Sheboygan County, when State Trooper Jim Reese stopped a car for speeding.
As Reese walked back to his cruiser after talking to the driver, a semi-trailer truck hit the side of the cruiser, with pieces of the cruiser flying off.
"If he had been walking on the left, or driver side of the vehicle, there's no doubt he would have been hit," said Capt. Nick Scorcio in a State Patrol news release.
Wisconsin's Move Over law requires drivers to shift lanes if possible, or slow down in order to create a safety zone for a law enforcement vehicle, ambulance, fire truck, tow truck or highway maintenance vehicle that is stopped on the side of the road with its warning lights flashing.
The semi-truck driver was cited for inattentive driving and failure to move over.
