Motor Vehicles, Titling and Registration - As enacted, redefines "hybrid electric vehicle" to clarify that it is a motor vehicle that is propelled by a combination of an electric motor and an internal combustion engine or other power source and components thereof. - Amends TCA Title 55, Chapter 4.

SB 1742 redefines "hybrid electric vehicle" in Tennessee law to mean a vehicle propelled by both an electric motor and an internal combustion engine (or other power source), excluding low-speed and medium-speed vehicles. This change directly affects vehicle registrants, dealers, and state agencies that classify vehicles under Tennessee's titling and registration system. The bill amends Title 55, Chapter 4 of Tennessee Code to clarify this definition in the existing legal framework. It does not create new taxes, fees, or regulatory requirements but ensures consistent application of the term for administrative purposes. The bill is procedural, focusing solely on defining terminology for vehicle classification.
