Conn. Agencies Regs. § 9-242a-17
After the checkers check off the name of an elector on the official check list, the ballot clerk shall issue such elector a ballot. The ballot clerk shall also offer the elector a privacy sleeve into which the ballot can be inserted so that the markings on the ballot cannot be seen or such sleeve may be placed in every voting booth for the elector's use. The elector shall not be required to accept a privacy sleeve. When a voting booth is available, the elector shall be directed to enter a booth and mark his ballot. The elector shall then be permitted to proceed to the voting tabulator and insert his ballot for counting. If the voting tabulator accepts his ballot, the elector shall immediately exit the polling place.
