Tenn. Code Ann. § 55-30-108

Except as otherwise provided in this chapter, this chapter exclusively governs the authorization of the operation and use of an ADS-operated vehicle when the ADS is engaged and in high or full automation mode, including, but not limited to, commercial use of ADS-operated vehicles. For motor vehicles operated at any other level of autonomous technology, as defined by § 55-9-105(c)(6)(B), the motor vehicle and driver shall be held to the same laws as conventionally operated motor vehicles, including the financial responsibility requirements of § 55-12-102, unless an exemption is specifically set out for a vehicle operated with any level of autonomy.
