A Southampton woman pleaded guilty to driving whilst impaired and being asleep at the wheel when stopped by Police, a court heard.

On March 28, Police on mobile patrol saw Isabella Hall, 50, of Granaway Heights, swerving in and out of traffic lanes on South Shore Road near the Swizzle Inn while driving slowly.

Crown Counsel Maria Sofianos told Magistrates' Court, after officers stopped the blue Ford Escort she was driving, they noticed her sleeping in the driver's seat.

She told officers that she was looking for her cell phone and said: "You guys give me a break, I'm a single mother and I'm not the worst criminal in the world."

When officers smelled alcohol on her breath, she was arrested and taken to Hamilton Police Station and gave a breath sample of 179 milligrams of alcohol in 100 millilitres of blood.

Magistrate Khamisi Tokunbo asked Hall if she had anything to say, she replied: "I did a stupid and irresponsible thing and I feel like an idiot."

Mr. Tokunbo fined her $800 with 80 days default and disqualified her from driving all vehicles for 12 months.
