1. At the term of the county commission in which such order is made, or at any subsequent term thereafter, the county commission shall appoint three special road district commissioners, who shall be voters of the district who shall hold their office until the second Tuesday in April thereafter. The voters of the district, at an hour and place to be fixed by said commissioners, shall elect three special road district 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 district commissioner to take the place of the one whose term is about to expire, who shall serve three years.

2. No person shall be elected or appointed commissioner who is not a voter of the district. Any vacancy caused by resignation, death, removal from the district of a special road district commissioner or sale of all land owned by him in the district shall be filled for the unexpired term by appointment by the remaining special road district commissioners of the district. All special road district 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 herein mentioned 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 district commissioners, then the county commission is hereby authorized and required to call an election to fill said vacancy.
