TN HB2608

Requires government officials to obtain a search warrant for felony investigations before accessing databases containing historical location data (records showing individual or vehicle locations more than 24 hours old), with exceptions for consent, exigent circumstances, and routine enforcement like tolls and parking

Mandates destruction of collected historical location data within 2-7 days unless a criminal defendant requests preservation, and prohibits selling such data to private third parties

Establishes detailed recordkeeping requirements for every data access instance, including accessor identity, purpose, supervisor approval, and monthly audits to detect potential misuse

Creates escalating penalties for violations: 7-day database access suspension for first offense, 30 days for second, permanent suspension for third; attorney general may bring civil action for injunctive relief

Makes historical location data accessed in violation of the act inadmissible as evidence in criminal or civil proceedings, and preempts local governments from enacting less restrictive laws
