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.

SB 2338 changes Tennessee's grant rules for volunteer fire departments by removing two specific restrictions. It eliminates the requirement to split annual grants equally among the state's three geographic regions (East, Middle, and West Tennessee) and removes the ban on using grant funds to purchase fire trucks or vehicles. These changes give fire departments more flexibility in how they allocate and use their state grant money. The bill amends Tennessee Code Annotated, Title 68, Section 68-102-154, and applies to grants awarded after June 30, 2026.
