I was turning onto hwy 75 from I39-90 in south Beloit Ill on 9-21-23 at 7:30 pm. I was in left lane global Express driver in right lane. As were turning global Express driver cuts into my lane and I slammed on my brakes and the trailer came within inches of my car. Followed driver into truck stop to see if he was intoxicated the driver said he changed his mind on lane change. This could have been a fatal accident.
