I was coming through Hartford (small town here in IL with the refineries) I was about to get onto Route 3 when I hear an air horn blaring well this Beelman Peterbilt (company truck) ran through the red light blaring his horn. I tried raising him on the cb but he didn't answer and it had my heart racing when I seen this unfold. I don't know if his brakes failed or what but I don't know if he was loaded or not cause he must have came from Alton cause he was going towards I-270. He seemed to be coasting but he sure wasn't doing the speed limit which is 55, I'd say he was getting her slowed down or at least trying to. Like I said I don't know if he lost his brakes or what but PLEASE always remember to do a pretrip!
