A DRUG driver who caused a crash on Greenock's Bullring roundabout was so doped up on a morphine-based painkiller that she didn't know what day of the week it was.

Jennifer Cabral asked police if it was Saturday or Sunday when it was actually Friday, and was deemed by a doctor to be still impaired more than three hours after the collision.

Cabral, 42, veered off lane in her silver-coloured Honda Jazz into the path of a grey Ford Focus which resulted in the other car being declared an insurance write-off.

The male driver of the Focus told a trial: "There was a mighty crash to the left side of my car and she got out of hers and seemed unsure about what had happened.

"She asked me to keep it between ourselves and not involve insurance companies.

"The best word I could use to describe her at the time is 'impaired'."

Cabral admitted taking co-codamol tablets for pain to a swollen right foot but insisted she hadn't taken enough of them to be unfit to drive.

She caused the 6.30pm crash on December 8 last year as a result of careless driving and being affected by the medication, which causes drowsiness.

A road traffic police sergeant told Greenock Sheriff Court: "She was very confused and didn't know what day of the week it was, or understand what I was asking her.

"She seemed out of it, not aware of what was round about her.

"She was asking whether it was Saturday or Sunday. It was Friday."

A police casualty surgeon who saw Cabral at 10pm said that she was still under the influence of the medication at that time.

Asked by lawyer Aidan Gallagher about the state she was in after the collision, Cabral said: "I just went into shock and confusion and my whole body felt like jelly.

"I was anxious and worried and in shock."

Cabral said that she took two tablets in the morning and another two around two hours after she got behind the wheel of her car.

But she conceded under cross-examination by prosecutor John Penman: "I took the tablets for my foot and I took them when I needed them for the pain."

Fiscal depute Mr Penman said: "I suggest you took more than what you're saying and it had a considerable effect on you."

Sheriff Daniel Kelly found Cabral guilty.

He told her: "In my view there is no doubt that there is consistent evidence throughout that your ability to drive was impaired and that you were unfit to drive."

Cabral, of Forsyth Street, was fined £300 and banned from the roads for 15 months.
