The Tennessee Instant Check System (TICS) is a background check program used to evaluate individuals before they purchase firearms in the state of Tennessee. It helps ensure that those who are prohibited from owning guns, such as felons or individuals with restraining orders, do not acquire them. TICS operates by quickly checking the applicant's information against various databases, including criminal history and mental health records. This process typically takes only a few minutes, allowing for efficient firearm transactions while maintaining public safety and compliance with federal and state laws.
