Only five days after an RCMP officer failed a breathalyzer test after being involved in a fatal collision in Tsawwassen, B.C., CTV has learned of another incident involving a Lower Mainland law enforcer and allegations of drinking and driving.

RCMP confirm a female New Westminster Police officer was involved in a crash involving alcohol.

The 47-year-old officer was driving an unmarked police van when she collided with two or more signs driving eastbound near the Westview exit in North Vancouver's Upper Levels Highway Oct. 17.

No charges have been laid, but the off-duty officer has promised to appear in court Dec. 17. She is facing impaired driving charges. Her name has not been released.

Cpl. Peter Thiessen, a spokesman for the RCMP, said the female officer provided two breath samples which were over the legal limit of .08.

On Saturday, RCMP officer Monte Robinson was allegedly driving a jeep when it collided with a motorcycle, killing 21-year-old driver Orion Hutchinson. Robinson later failed a breathalyzer.

Robinson was one of four officers who were also involved in a high profile Taser incident that led to the death of Polish immigrant Robert Dziekanski at Vancouver airport last year.

The RCMP officer was released on a promise that he will attend Surrey Provincial Court in January 2009. He will face charges of impaired driving causing death.
