A motorist who spent two days on a life support machine after crashing on black ice is suing the Highways Agency for failing to grit the road properly.The 47-year-old man, who is a member of the Royal Navy, sustained serious injuries after his car was involved in a three-vehicle collision at Trewint, near Launceston, Cornwall on Jan 21. He spent three weeks in hospital and is still suffering health problems as a result of the crash. The victim, from Liskeard, Cornwall, was one of 30 drivers whose cars crashed on a 40-mile stretch of the A30, which runs running from Okehampton in Devon to Bodmin, Cornwall. No motorist has mounted a successful claim against the agency. But, according to Richard Biggs, the unnamed motorist’s solicitor, a successful claim could trigger action from other drivers. More
