Fire Prevention and Investigation - As enacted, requires the commissioner of commerce and insurance to fulfill certain duties for the volunteer firefighter vehicle grant program, which is established to annually provide grants to select volunteer fire departments to assist with local match requirements for federal grants to purchase vehicles. - Amends TCA Title 68.

HB 2446 removes two specific restrictions on grants for Tennessee's volunteer fire departments. It eliminates the requirement that annual grant funds must be equally divided among the state's three grand divisions (East, Middle, West) and removes the ban on using grant money to purchase fire trucks or vehicles. This change gives local fire departments more flexibility in how they allocate funds and use them for equipment. The bill directly affects volunteer fire departments receiving state grants under Tennessee Code Annotated Title 68. The changes apply to grants awarded after June 30, 2026.
