What is the purpose of voter registration?

Voter registration serves primarily to enable individuals to participate in elections. It is a crucial process that ensures that only eligible citizens have the right to vote, helping to maintain the integrity of the electoral system. By registering to vote, individuals indicate their intention to engage in the democratic process, allowing them to cast ballots for their preferred candidates and on various issues during elections.

The other options don't fulfill this specific function. Notifying the government of a change of address is important for various administrative reasons but does not directly relate to voting. Reporting taxes is a separate obligation citizens have concerning their financial responsibilities to the government, and applying for a driver’s license pertains to motor vehicle regulation, which is distinct from electoral participation. Voter registration is specifically about providing the means for individuals to exercise their right to vote.
