Which of the following is NOT a requirement to vote in Pennsylvania?

In Pennsylvania, the requirement to vote includes being a U.S. citizen, being at least 18 years old, and being a resident of the state. Having a driver's license is not a prerequisite for voting. Voters can register and participate in elections without a driver's license, as there are other forms of identification that can be used. Therefore, the statement that one must have a driver's license to vote is incorrect and identifies it as the outlier among the listed requirements. Ensuring that voters have a valid means of identification is essential, but it does not specifically mandate a driver’s license as a necessary document for voting in the state. This distinguishes it from the other correct requirements, which are foundational to voter eligibility in Pennsylvania.
