What Is Causation?
Causation is the connection between an act or event and the harm that follows. In a personal injury claim, causation links another party’s conduct to the person’s injury and losses. Evidence may include crash details, medical records, witness accounts, and expert analysis that explain how the event produced the claimed harm.

Key Takeaways About Causation
- Causation connects conduct with a specific injury.
- Medical evidence can explain how the accident caused harm.
- Causation is different from fault or negligence.
How Causation Works

Causation connects the conduct at issue with the injury described in a claim. The analysis asks whether the event produced the harm and whether the claimed losses follow from that harm. A crash report may describe what happened, while medical records can connect the event to a diagnosis or treatment.

Truck accident claims may involve several possible causes, including driver conduct, vehicle conditions, cargo handling, or road conditions. Evidence must fit together in a clear sequence. Proximate cause addresses whether the connection is close enough under the law, while medical records help explain the injury’s timing, nature, and progression.

From the Atlanta Auto Law team
When we review causation in truck accident claims, we compare the crash evidence with medical records and the claimed losses. We also examine whether another event could explain the injury. Our team keeps the analysis focused on the factual connection between the truck collision and the harm described.
Causation in Practice: A Real-World Example
A truck changes lanes and strikes a passenger vehicle, causing the driver to suffer neck pain that begins after the collision. Medical records and witness accounts may support causation by connecting the impact with the reported injury.
