Illinois data shows that large-truck crashes remain a serious problem. IDOT reported that crashes involving large trucks in 2024 were 4.1 percent higher than the previous four-year average and 1.4 percent higher than in 2023.
Commercial vehicle litigation in Illinois depends on detail and evidence.
Critical evidence can include electronic logs, black-box data, maintenance files, dispatch records, video, cargo documents, and the truck itself. Each piece helps rebuild what happened in the hours, minutes, and seconds before impact.
Electronic Logging Device data may show whether the truck was moving, how long the driver had been working, and whether the recorded rest periods seem believable.
It may also reveal edits.
That matters because the final version of a log may not tell the whole story. Original entries are generally retained when changes are made, which allows the legal team to compare the first record with the edited one.
The truck’s event recorder may provide another layer of evidence.
Depending on the hardware, it may record:
- Speed
- Engine RPM
- Braking activity
- Throttle position
- Cruise-control use
- Fault codes
- Vehicle movement
A spoliation of evidence letter tells the trucking company and other parties to preserve specific records, devices, vehicles, and electronic information. The letter should be detailed. A vague demand to “save everything” can leave a lot of room for arguments later.
A stronger letter identifies the ELD files, engine data, dashcam footage, inspection records, dispatch communications, maintenance documents, driver files, and the physical truck and trailer.
The police report matters as well, but it doesn’t replace a full civil investigation.
