Modifies provisions relating to ambulance districts

HB 1541 revises how ambulance district directors are elected and structured in Missouri counties. It requires most counties to divide ambulance districts into six election districts (with population balance), where voters elect directors from their district, resulting in staggered terms (1, 2, or 3 years). In specific counties adjacent to large charter counties, directors are elected at-large for three-year terms, with existing directors continuing until term expiration. The bill also sets candidate qualifications (e.g., residency, age), allows voter-approved changes to board size (e.g., increasing to seven members), and outlines vacancy procedures.
