Ian Smith made his comments after recording a verdict of accidental death on 26-year-old Clive Wilding, from Ulverston.

Mr Wilding died in a three vehicle collision on the notorious stretch at High Newton.

He was driving back to Furness along the A590 on 14 February 2003, when his car failed to take a left hand bend and collided with a scaffolding wagon.

He was killed instantly.

Margin of error

A van then collided with the back of the lorry which had come out across the road.

The inquest heard Mr Wilding had been at the dentists but had not been in pain and had not had anaesthetic.

He was said to be in a good mood, and had not been drinking or using his mobile phone.

No defects were found on his car, and the Mr Smith ruled that Mr Wilding must have momentarily taken his eyes off the road.

Recording a verdict of accidental death, he said he'd write again to the south Cumbrian MPs and the Government, because he said the A590 offered no margin of error for drivers.

In March this year, three teenagers died on the Bouth Lane End to Greenodd stretch of the A590.

Gareth Lewis, 18, and Victoria Clarke, 15, both from Grange-over-Sands were killed along with 19-year-old Anthony Ramsden in the accident.
