A drunk motorcycle instructor fell off her bike three times as she gave a lesson in Bradford, a court was told.

On the last occasion, her pupil heard her cry out through the headphone link: “Ow, I’ve hurt my leg!”

Police found two bottles of brandy – one empty and one three-quarters full – in Sandra Kenyon’s motorcycle jacket after she fell off for the third time, Bingley magistrates heard yesterday.

Kenyon, a 46-year-old mother-of-two, admitted riding a motorcycle with excess alcohol. The court was told she had 131 microgrammes of alcohol in 100 millilitres of breath – almost four times the limit of 35mcg.

Presiding magistrate Ian Cowling warned her that she could be facing a prison sentence or a lengthy community order.

He told Kenyon the result of her actions while in such a state as she rode through the city centre at 10.30am could have been “catastrophic”.

The Bench adjourned sentence for reports to be prepared and told Kenyon she must return to court on April 6. She was made the subject of an interim driving ban.

Nadine Clough, prosecuting, said Kenyon had been giving instruction to learner biker Philip Hopkins on Wednesday, March 3.

Shortly after setting off from Holme Wood, Bradford, Kenyon “dropped” her motorcycle and needed help to get back on.

Miss Clough said: “Driving towards Dudley Hill roundabout and approaching the traffic lights at Cineworld, Kenyon was on the floor again and needed help with the bike.

“She seemed to be shaking and apologised, saying it was the first time she had dropped the bike.”

Mr Hopkins and Kenyon carried on towards Shipley but, as he approached a roundabout in Wrose Road, Mr Hopkins could not see her following him.

Then he heard over the radio link the cry “Ow, my legs!” He turned round and went back and saw 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, one empty and the other opened with a quarter of the drink missing.

Kenyon told officers the empty bottle had been consumed the day before and she had only had a mouthful that day.

“When interviewed, she told officers she needed help,” said Miss Clough.

The Bench was told that Kenyon, of Northedge Park, Hipperholme, near Halifax, was no longer working as an instructor.

She was suffering from depression and was taking medication and occasionally used alcohol to assist her problem.

After the hearing, Roger Stanley, of Ridesafe Motorcycle School, based in Holme Wood, told the Telegraph & Argus that Kenyon had been sacked on the day of the offence.

He said: “It was a big shock. We have very high standards and I was disgusted with what happened.

“I didn’t know she had a problem, neither did any of the instructors.”

Kenyon had worked for Ridesafe for nine years and had been employed on a sub-contractual basis, said Mr Stanley.
