Two Illinois State Police squad vehicles were damaged in Joliet by motorists who failed to move over on Interstate 80.

The first crash occurred about 4 a.m. Monday on the westbound lanes of I-80 near Houbolt Road in Joliet, according to a statement from Illinois State Police.

“Trooper was stopped behind a crash scene with their emergency lights activated when a vehicle failed to move over and side swiped the driver’s side of the trooper’s squad car,” police said.

The trooper was inside of his squad car at the time of the crash but was uninjured, police said.

The driver who struck the trooper’s vehicle was issued a citation for what’s known as a Scott’s Law, or Move Over Law violation.

The second crash involving a state police vehicle occurred about 4:10 a.m. while another trooper was assisting with the first crash related to the Move Over Law violation, police said.

Another vehicle passing the crash scene failed to move over and struck one of the vehicles in the initial crash, which then got pushed into the second trooper’s squad vehicle, police said.

That driver was also issued a citation for a Move Over Law violation, police said.
