A study was conducted by IDOT's Division of Traffic Safety to identify when most of fatal crashes between trucks and other vehicles, are occurring and under what circumstances.

Here are the results of that study:
In Illinois, fatal crashes between trucks and other vehicles most often occur:

• On Tuesday through Friday, between 11:00 a.m. and 5:00 p.m., when the weather is clear and the road is dry.
• Due to improper speed or improper lane use.
• When the truck driver is between 28-43 years old and the driver of the other vehicle is between 20-30 years old.
• When the driver (of the truck OR the other vehicle) has fallen asleep or has been drinking.
