The lieutenant governor decides all questions of parliamentary procedure in the Senate.

The lieutenant governor also has broad discretion in following Senate procedural rules.

The lieutenant governor is also a member of the Legislative Redistricting Board (together with the speaker of the House, attorney general, comptroller, and land commissioner), which is charged with adopting a redistricting plan for the Texas House of Representatives, Texas Senate, or U.S. House of Representatives after the decennial census if the Legislature fails to do so.

In the case of a vacancy in the lieutenant governor's office, the Senate elects one of its members to act as President of the Senate until the next statewide office election, in effect becoming the lieutenant governor.

Texas is one of the few states that vests significant power in the office of lieutenant governor, making it among the most influential.
