Causation

Causation is the link between someone’s careless driving and the injury you actually suffered, and a claim fails without it even where carelessness is obvious.

It is not enough to show the other driver was negligent in general; your claim needs to show that this particular negligence caused this particular harm. Medical evidence plays a central role here, especially where you had a pre-existing condition and the question becomes how much of your current state the accident actually caused.

Causation issues often arise with injuries that developed or worsened over time, where a clear medical timeline linking the accident to your symptoms strengthens the claim considerably.

Who is at fault explains how causation fits with the other elements of a claim.
