The office holder's constitutional roles are to serve as the president of the Indiana Senate, become acting governor during the incapacity of the governor, and become governor should the incumbent governor resign, die in office, or be impeached and removed from office. Lieutenant governors have succeeded ten governors following their deaths or resignations. The lieutenant governor holds statutory positions, serving as the head of the state agricultural and rural affairs bureaus, and as the chairman of several state committees.
