1. At the meeting of the county commission in which such order is made, or at any subsequent meeting thereafter, the county commission shall appoint three special road subdistrict commissioners, who shall be voters of the subdistrict who shall hold their office until the second Tuesday in April thereafter. The voters of the subdistrict, at an hour and place to be fixed by the commissioners, shall elect three special road subdistrict commissioners, one of whom shall serve one year, one for two years, and one for three years, and on municipal election days each year thereafter they shall elect a special road subdistrict commissioner to take the place of the one whose term is about to expire, who shall serve for three years.

2. No person shall be elected or appointed as a commissioner who is not a voter of the subdistrict. Any vacancy caused by resignation, death, removal from the subdistrict of a special road subdistrict commissioner or sale of all land owned by him in the subdistrict shall be filled for the unexpired term by appointment by the remaining special road subdistrict commissioners of the subdistrict. All special road subdistrict commissioners shall qualify by taking, subscribing and filing with the county clerk the oath prescribed by the constitution of this state, and that they will faithfully, honestly and impartially discharge their duties as commissioners according to law.

3. If for any reason the board of commissioners shall fail to call an annual election to fill a vacancy or vacancies caused by the expiration of the term of any one or more of the special road subdistrict commissioners, then the county commission is hereby authorized and required to call an election to fill such vacancy.
