Relating to the composition and authority of certain subregional boards of regional transportation authorities.

SB 2118 amends Texas Transportation Code sections governing subregional boards of regional transportation authorities. It establishes a rotating presiding officer role (serving two-year terms with no consecutive terms), revises voting rules so principal municipalities appoint members proportional to their allocation (with votes equal to their allocated number), and sets staggered two-year terms for board members. The bill directly affects municipalities within regional transportation authorities that appoint board members. These changes streamline board operations and clarify membership representation, replacing prior sections about board elections and term structures.
