Road accident experts have filmed a "nightmare" junction where their boss was killed to help launch a campaign to close it.

The damning video evidence was shot by Tadcaster company Sky High Traffic Data, set up by David Calvert to identify and eliminate accident blackspots.

Ironically, Mr Calvert, 38, was killed when his Audi car was in a head-on collision with a lorry at a junction near his home, where he had predicted someone would be killed.

Selby MP John Grogan now plans to invite county highways chiefs to watch the video footage of the A659 junction with Toulston Lane, near Tadcaster, before it claims another life.

The video - taken at the request of David's heartbroken parents - reveals how motorists regularly risk their lives trying to negotiate the turn-off.

The junction is on a "blind bend" on an incline, and vehicles travelling towards the A64 have to wait perilously in the middle of the road before turning right.

David's father, Bill Calvert, 75, said today: "Closing the junction won't bring our son back, but hopefully it will save other lives.

"The video is horrendous with vehicles on a blind bend waiting to turn right with unsuspecting drivers coming up behind. It makes the hairs on the back of your neck stand on end.

"David said it was an accident waiting to happen and tragically he was proved right."

Mr Calvert and his wife, Delia, 76, said there was no reason why the junction should not be closed as there was another much safer right turning just a bit further along the A659.

David, who lived with his parents in the grounds of Tadcaster Grammar School, died nine days after the crash left him brain-damaged.

An inquest heard that lorry driver Robert Ward was approaching the junction from Tadcaster when he braked sharply as a car in front was turning right into Toulston Lane.

He skidded on to the offside of the road, colliding head-on with Mr Calvert's Audi which was on the near side grass verge trying to avoid the lorry.

* It was Sky High's video surveillance footage which revealed the unbelievable risks drivers were taking as they negotiated central gaps on the A64 between Tadcaster and York - sparking a Press campaign to close the gaps.

** Self-employed haulier Robert Ward, aged 33, of Kippax near Leeds, admitted driving without due care and was banned for 12 months, fined £300 with £55 court costs.
