Determining Each Vehicle’s Role in a Three-Vehicle Crash
When three vehicles are involved in the same collision, investigators may need to determine where the crash began and what happened next. The fact that a semi-truck and two passenger vehicles were involved does not establish which vehicle caused the first impact.
Investigators may examine where each vehicle was traveling before the collision, the points of impact, final vehicle positions, debris, tire marks, and damage patterns. Witness statements and available video may provide additional information.
This distinction can matter when determining liability. One driver may cause the initial collision while another driver’s actions contribute to a later impact. In other cases, one event may set off a chain reaction that gives the other drivers little or no opportunity to avoid the crash.
An Ankin Law truck accident lawyer can investigate the sequence of a multi-vehicle collision and identify the parties and insurance coverage that may be involved.
Semi-Trucks Can Produce Evidence That Passenger Vehicles Do Not
A collision involving a truck-tractor semi-trailer may create sources of evidence that are not typically available after an accident involving only passenger vehicles.
Depending on the truck and its operation, relevant information may include electronic logging device records, vehicle inspection documents, maintenance records, dispatch information, driver qualification records, and electronic data from the truck itself.
Some records may help establish how long a driver had been working or driving before the collision. Others may show whether the truck had recently undergone maintenance or whether mechanical issues had previously been identified.
The existence of these records does not mean a trucking company or truck driver caused the Oak Brook collision. Authorities have not announced a cause. If questions about the semi’s operation arise, however, those records may become important to understanding what happened.
A Trucking Company May Have Responsibilities Beyond the Driver
If a truck driver contributes to a collision while performing work duties, determining responsibility may involve examining the company connected to the truck.
The relationship between the driver, trucking company, tractor owner, trailer owner, and other businesses may need to be established. Depending on the circumstances, investigators may also examine hiring, training, supervision, maintenance, or other company responsibilities.
Commercial trucking operations can involve several companies. The business shown on a truck does not necessarily identify every party connected to its operation.
Identifying those relationships can help determine which insurance policies apply and whether responsibility extends beyond an individual driver.
Four Injured People May Mean Several Claims and Insurance Issues
Four people were hospitalized following the I-88 collision. It is not yet clear which vehicles they occupied or how seriously they were injured.
When several people suffer injuries in one crash, insurance issues can become more complicated. Multiple injured people may seek compensation under the same liability policy, and available policy limits may have to cover more than one person’s losses.
Additional insurance coverage may also apply depending on the vehicles involved, who caused the crash, and the policies available to the injured people.
A personal injury claim can involve medical expenses, lost income, future treatment, pain and suffering, and other qualifying damages. Identifying all available coverage can be particularly important when several people suffer substantial losses in the same collision.
Frequently Asked Questions After a Multi-Vehicle Semi-Truck Crash
What if I do not know which of the other vehicles caused my injuries?
You do not need to determine fault yourself before exploring your legal options. In a three-vehicle collision, investigators may need to reconstruct the order of impacts and determine what each driver was doing. Police records, vehicle damage, witness accounts, video footage, and electronic information may help establish which actions contributed to your injuries.
What if the semi-truck driver says another vehicle caused the crash?
Disagreement about fault does not determine who is legally responsible. In a multi-vehicle crash, statements from the drivers are only part of the evidence. Investigators may compare those accounts with vehicle damage, video footage, electronic truck data, witness statements, and physical evidence from the roadway. More than one driver’s actions may also contribute to the same collision.
Should I talk to the trucking company’s insurance adjuster after the crash?
You may be contacted by an insurer seeking information about the collision, your injuries, or your medical treatment. Be careful about giving a recorded statement, signing documents, or agreeing to a settlement before you understand the extent of your injuries and which insurance policies may apply. An early settlement may not account for additional treatment, lost income, or other losses that become clear later.
What if I was a passenger and do not know how the crash happened?
Passengers generally do not need to know which driver caused a collision before seeking information about their rights. An investigation can determine whether one or more drivers contributed to the crash. As a passenger, keeping medical records, insurance correspondence, and information about the vehicle you occupied can help document your injuries and connection to the collision.
Can trucking evidence disappear after the semi is returned to service?
Some evidence can change or become unavailable as time passes. A truck may be repaired and returned to service, electronic information may be overwritten, and businesses may retain different records for different periods. When trucking records or vehicle evidence could matter to a claim, identifying and preserving relevant information early may help prevent its loss.
