Honolulu police officers will begin manning sobriety checkpoints beginning Sunday at unannounced times and locations.

This includes, but is not limited to, the Veteran’s Day, Thanksgiving, Christmas, and New Year’s Eve holidays through Dec. 31.

It is all part of the department’s ongoing efforts to reduce traffic injuries and deaths.

Hawaii’s legal drinking age is 21. Promoting intoxicating liquor to a person under the age of 21 is a misdemeanor punishable by up to one-year imprisonment.
