Alabama Code Title 11. Counties and Municipal Corporations § 11-46-50

(a) The election officials, where voting machines are used, shall ascertain whether each applicant to vote is entitled to vote, and each applicant found to be entitled to vote shall be permitted to vote in the manner provided in this article. Each applicant to vote shall identify himself or herself to the chief clerk, who shall examine the list of qualified electors furnished by the municipal clerk and, if such voter's name appears on such list, the chief clerk shall mark the applicant's name off the list. The applicant, unless unable to write his or her own name because of physical handicap or illiteracy, shall then sign his or her name on the poll list on the line numbered to indicate the order in which the voters cast their ballots, and the clerk shall record the voter's name on a second poll list on the line numbered to indicate the order in which the voter cast his or her ballot. Thereafter, the voter shall be admitted within the voting machine booth and permitted to vote.

(b) If the applicant is unable to sign his or her name because of physical disability or illiteracy, his or her name shall be written for him or her in the manner prescribed in subsection (e) of Section 11-46-39 for the writing of names of voters on the poll list at polls where paper ballots are used.

(c) If the applicant's name is not on the list of qualified voters, the applicant shall not be allowed to vote except by provisional ballot.
