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.

HB 1874 clarifies the legal definition of "hybrid electric vehicle" in Tennessee law. It specifies that such vehicles must be propelled by a combination of an electric motor and an internal combustion engine (or other power source), while explicitly excluding low-speed and medium-speed vehicles. This change updates the existing statute (TCA Title 55, Chapter 4) to provide clearer terminology for vehicle classification. The bill does not create new requirements or affect existing regulations - it only refines how hybrid vehicles are defined for administrative purposes.
