Relating to: nonfunctional and counterfeit airbags and providing a penalty.

AB 523 bans the sale, installation, or distribution of counterfeit airbags (fake parts with misleading marks) and nonfunctional airbags (previously deployed, damaged, or falsely labeled as working). It directly affects auto parts sellers, installers, and repair shops by prohibiting these practices, with limited exceptions for police vehicles, dealers without knowledge of issues, and insurance-related vehicle transfers. Violations carry fines up to $5,000 or up to one year in jail per offense, escalating to felony charges for repeat offenses or if harm or death results. The bill creates specific definitions for these airbag types and establishes penalties under existing statute 347.50.
