HB 682 aims to regulate firearm sales at gun shows by introducing new criminal offenses. It requires background checks through the National Instant Criminal Background Check System for all firearm sales at gun shows, with exceptions for sales to licensed carriers and peace officers. It further requires gun show promoters to provide prior notice of the event to local law enforcement, post compliance notices, and ensure background checks for all non-licensed dealer sales. Violations are classified as Class A misdemeanors, with the law set to take effect on September 1, 2025​.
