A truck accident settlement can take several months to more than a year, depending on injury severity, medical treatment, evidence disputes, and the number of liable parties. Cases involving drowsy driving often require driver logs, black-box data, dispatch records, and carrier policies. Settlement usually becomes clearer once medical treatment stabilizes and damages can be fully documented.
