Illinois State Police officials are warning drivers cops will be out in full force this holiday weekend. About 100 roadside safety checks are scheduled across the state in an effort to crack down on drunk driving. Over the past five Labor Days, 25 people have died from drunk drivers in Illinois.

Bob Park, with the state’s Department of Transportation, said the number of fatalities from drunk drivers over the holiday weekend have dropped over recent decades.

“The culture has changed,” Park said. “When you take a look at the statistics and you look at the death rate, I mean, having the lowest death rate sinec the 1920s, obviously what we’re doing is working.”

Police warn that most drunk driving incidents happen at night. Drivers caught under the influence could face jail time or have their license suspended.
