Proposing an amendment to the Constitution of the United States extending the right to vote to citizens sixteen years of age or older.

H.J. Res. 16 proposes a constitutional amendment to extend voting rights to all U.S. citizens aged 16 and older, repealing the 26th Amendment that currently sets the voting age at 18. It would directly affect 16- and 17-year-old citizens by allowing them to vote in federal elections for the first time. The amendment grants Congress authority to pass laws enforcing this change, and requires ratification by three-fourths of state legislatures within seven years to become part of the Constitution.
