Relates to lease terms for zero-emission school buses

This bill extends the maximum lease term for zero-emission school buses from 5 to 12 years, allowing school districts to secure long-term agreements without annual voter approval for these specific vehicles. It directly affects school districts purchasing or leasing zero-emission buses by permitting longer contracts (up to 12 years) compared to standard school buses (max 5 years). The key change adjusts budgeting rules so districts using 12-year leases for zero-emission buses must calculate related costs over the full lease period for funding purposes. The bill does not alter lease terms for conventional buses or require new voter approvals for standard bus leases.
