The all-Republican Board of County Commissioners voted unanimously to adopt an ordinance making English the official language of Carroll County's government.
Carroll joins Frederick and Queen Anne's counties in adopting such a policy.
The measure, introduced in September by Commissioner Haven Shoemaker, would require the county's official actions and statements to be in English. But it wouldn't prohibit county employees or elected officials from communicating in other languages for unofficial business.
Proponents say the measure sends a message that undocumented immigrants aren't welcome in Carroll County. Opponents say it's an unnecessary law that will make even documented immigrants feel unwelcome.
