Subchapter II. Regulations Governing Conduct of Elections During Hours of Voting
§ 4943. Voting assistance based on blindness, disability, or illiteracy; instructions for voters.

(a) Any voter who requires assistance to vote by reason of blindness, disability, or inability to read or write may be given assistance by a person of the voter's choice, other than the voter's employer or agent of that employer or officer or agent of the voter's union.
(b) Any election officer may provide instruction or information for a voter through use of 1 of the sample ballots posted in the voting room.
(c) Whenever a voter requests further instructions in the manner of voting or the operation of the voting machine after having entered the voting machine booth, 2 election officers of opposite political parties shall jointly give such instructions. In doing so, the officers shall take care not to assist the voter in any manner that might influence that voter's vote. After giving instructions, both officers shall retire before the voter begins to register that voter's vote, which the voter shall do in secret at all times.
