Which State Is Better for Plaintiffs?
Based on the rules above, Illinois is generally more favorable for personal injury plaintiffs. Key factors include the comparative negligence standard, damage caps, and statute of limitations. However, the best state for your specific claim depends on where your injury occurred — you must file in the jurisdiction where the accident happened.
