A 30-year-old Smiths Falls woman is facing criminal charges after a police officer watched her yell at a closed fast food drive-thru and then run a red light.

It happened early Friday morning at about 2:40 a.m., Smiths Falls Police said in a media release, when a patrol officer watched the woman pull up to the drive-thru window of a restaurant on Beckwith Street.

It is alleged the driver yelled at the intercom for several minutes, trying to place an order despite the restaurant being closed. - Smiths Falls Police media release

"It is alleged the driver yelled at the intercom for several minutes, trying to place an order despite the restaurant being closed," the media release states.

The officer then followed the woman as she pulled out onto Beckwith Street, and watched as her vehicle ran a red light at the intersection of Beckwith and Chambers streets.

The officer suspected the woman had been drinking and placed her under arrest. She then provided two breath samples that were three times over the legal limit, Smiths Falls police said.

The woman was charged with impaired operation of a motor vehicle and being over the legal blood-alcohol limit.

She was released on a promise to appear in court.
