Bill Summary · SB 1742

Legislative bill overview

SB 1742 amends Tennessee's motor vehicle code to provide a legal definition of "hybrid electric vehicle" as a vehicle powered by both an electric motor and an internal combustion engine or other power source working together. The bill clarifies existing terminology in the state's titling and registration statutes.

Why is this important

Clear legal definitions in vehicle codes affect how vehicles are classified for registration fees, insurance purposes, tax incentives, and regulatory compliance. This definitional clarification ensures consistent application of hybrid vehicle regulations across state agencies and prevents disputes over vehicle classification.

Potential points of contention

  • Scope ambiguity: The phrase "or other power source" is broad and could create uncertainty about what qualifies as a hybrid vehicle going forward (e.g., hydrogen fuel cells, compressed natural gas combinations)
  • Incentive implications: Clarifying hybrid definitions may affect existing tax breaks, HOV lane access, or emissions-based incentives that currently apply to hybrids
  • Retroactive application: Unclear whether this definition applies to previously registered vehicles or only affects future registrations, potentially creating inconsistencies
