A motorcycle instructor from West Yorkshire has been sacked after she was found guilty of drink-driving while giving a lesson.
Bingley Magistrates' Court heard Sandra Kenyon, 46, had 131 microgrammes (mcg) of alcohol in 100 millilitres of breath when police tested her.
The legal limit is just 35mcg officials told the court.
Kenyon, of Hipperholme, Halifax, fell off her bike three times during the lesson it was revealed.
Roger Stanley, of Ridesafe Motorcycle School, confirmed she was sacked on March 3, the day the lesson took place.
Kenyon had worked for Ridesafe for nine years and had been employed on a sub-contractual basis, Mr Stanley added.
The case was adjourned for the preparation of reports and Kenyon was told she must return to court on April 6 for sentencing.
The court was told Kenyon had been giving instruction to a learner biker but shortly after setting off she dropped her motorcycle and needed help to get back on.
The rest of the lesson continued in a similar fashion and ended with Kenyon on the ground with a number of people gathered round her.
When police arrived and removed her motorcycle jacket they found two bottles of French brandy. Kenyon told officers the empty bottle had been consumed the day before and she had only had a mouthful that day.
