Illinois uses modified comparative fault with a 51% bar, so plaintiffs bearing majority fault cannot recover. The 2-year statute of limitations applies to most personal injury claims, with special tolling for minors. Illinois courts — particularly in Cook County — are known for significant personal injury verdicts, partly because the state has no cap on noneconomic damages following the Illinois Supreme Court's constitutional ruling striking down prior caps. Illinois does not require no-fault PIP coverage; all auto injury claims follow the at-fault tort system. Chicago-area litigation includes a high volume of trucking accidents on interstate corridors, construction site injuries under the Illinois Structural Work Act (now repealed), and premises liability at commercial properties. Product liability follows strict liability principles. Illinois requires a section 2-622 expert certificate for medical malpractice claims at filing. Punitive damages are available in cases of fraud, actual malice, or deliberate violence.
