Highways, Roads and Bridges - As introduced, authorizes surveillance cameras to be installed on federal interstate highways and operated by a state entity to aid in the investigation and prevention of terrorism and state criminal offenses other than traffic violations; authorizes surveillance cameras to be installed on public roads and highways other than federal interstate highways and operated by local law enforcement agencies to aid in the investigation and prevention of terrorism and state criminal offenses other than traffic violations. - Amends TCA Section 55-8-198.

HB 294 would allow state entities to install surveillance cameras on federal interstate highways for security purposes (like preventing terrorism or serious crimes, not traffic enforcement) and permit local law enforcement to install cameras on non-interstate public roads for the same security goals. The bill prohibits using these cameras to issue traffic citations or monitor routine violations, requiring local governments to get state approval before installing cameras on state roads. It also mandates that camera operations must not interfere with traffic safety and must be operated exclusively by law enforcement for security investigations.
