A police lieutenant was canned early Sunday after crossing over the blurry blue line — when her fellow officers discovered their drunken colleague driving backwards, honking, through the streets of Florida.

Now ex-cop Christi Ruhtz, 41, was discovered with bloodshot, glassy eyes and reeking of booze in Pinellas, Florida around 2:00 a.m., reported the Tampa Bay Times.

Someone called 911 to report her bizarre driving, and she failed numerous sobriety tests, the site said. A breathalyzer showed her blood alcohol level at 0.14, well above the legal limit of 0.08.

Rhutz, who’d been with the Pinellas County Sherriff’s Office since 1998, was immediately fired, according to the report.

She was charged with a DUI, and released without bail.
