Motor Vehicles, Titling and Registration - As introduced, subjects plug-in hybrid electric vehicles, instead of all hybrid electric vehicles, to the $100 additional vehicle registration fee for electric vehicles. - Amends TCA Section 55-4-116.

SB 1839 changes Tennessee's vehicle registration fee structure by removing the $100 additional fee from regular hybrid electric vehicles (HEVs) and applying it only to plug-in hybrid electric vehicles (PHEVs). This directly affects owners of HEVs, who will no longer pay this fee, while PHEV owners will continue to pay the $100 annual registration charge. The bill amends Tennessee Code §55-4-116 to specify that the fee applies solely to plug-in hybrids, effective January 1, 2027. This is a policy adjustment to narrow the fee's scope, not a new fee for all electric vehicles.
