Mark Trevelyan (35) crashed his Kawasaki Ninja bike while overtaking a Vauxhall Vectra on the Tibshelf to Holmewood road on 4th April at about 6.40pm.

He left the road and was thrown from the machine before coming to rest in bushes, where he died from multiple injuries.

Post-mortem examination tests revealed 359mgs of alcohol in 100mls of blood, more than four times the limit for motorists.

Witness Gordon Wallace, of Eastern Avenue, Bolsover, told the Chesterfield inquest on Friday he was driving towards Holmewood on his way home from work when the bike came up behind his car at an estimated 80-90mph.

The motorcycle overtook him on double-white lines on a sweeping left-hand bend near Oilwell Nursery, Hardstoft.

Mr Wallace expected the bike to complete the manoeuvre and tuck back in front of his car.

"He slowed down and I thought he was going to go around the corner on the wrong side of the road, but it was like he made no attempt to take the corner, he just went straight," said Mr Wallace.

Mr Wallace told the inquest he stopped and found Mr Trevelyan a metre off the ground among bushes and trees with no signs of a pulse.

Nicola Spencer told the inquest she was driving her Renault Clio towards Tibshelf when she saw the green motorcycle on her side of the road.

She said: "There was a flash of lime green and he passed me on my nearside. I thought his speed was like 100mph, but I don't know – it just seemed like a blur."

Collision investigator Pc Janet Garner said: "The rider failed to negotiate the bend and continued almost straight on, mounted the kerb and went upright into a hedge where he came to rest.

"Witnesses suggest he was overtaking other vehicles in contravention of double-white lines."

Recording a verdict of accidental death, Deputy North Derbyshire Coroner Nigel Anderson said: "The evidence suggests he had more than enough time to take the bend and had allowed himself most of the road to do that, but he didn't commit himself to taking the corner.

"Perhaps by the time he had committed himself there was an oncoming car and he had no alternative but to go around it.

"The amount of alcohol had affected his driving judgement and this seems to be the only explanation that carries any weight."
