This is the terrifying moment a lorry veered across the a motorway central reservation, heading into oncoming traffic and narrowly missing a £100,000 Porsche.
Peter Stone, 55, was driving his Porsche 911 home from a family outing to St Agnes when he saw a lorry hurtling towards him between junctions 28 and 29 - between Cullompton and Exeter, in Devon - at 12.23pm on Friday, August 1.
The father of two, who was in the right-hand lane heading north, had mere seconds to react to avoid what could have been a deadly collision. He managed to swerve into the middle lane just in time as the lorry driver sped the wrong way down the busy motorway.
Peter, who manages a fleet of vehicles for a waste company and is from Reading, Berkshire, said: "It literally came out of nowhere. I think I had less than two seconds to move before getting flattened by the tipper driver.

"It was quite difficult, my car is quite low down and the black car (in front) sort of obscured my view. I only really saw the truck - luckily it was yellow, so your peripheral vision can pick up bright colours and stuff.
"The black car moved out in front of me, I had a white motorhome beside me and I managed to go in between them. It was just a reflex reaction really. I'm very surprised no-one actually smashed into the truck.

"I did speak to the transport company because I wanted to make sure no-one was injured before offering to share the footage. I pulled over straight away and called 999, assuming there was going to be some serious injuries.
"Fortunately, as far as I'm aware, no one was injured - which is quite remarkable."
Peter recorded the devastating scene on his front and rear dashcams, which had been fitted by the dealership when he bought the car last December.
Peter, who holds an HGV licence himself, said: "You've seen videos of trucks crossing central reservations, but for it to happen straight in front of you is bizarre.
"Until I reviewed the video I hadn't even realised I was in the fast lane. In my recall I thought I must have been in the middle lane, there's no way I could have been in the third lane. I've had two nights of uninterrupted sleep replaying it in my mind, trying to come to terms with basically probably being two seconds from serious injury or even worse."
A National Highways spokesperson confirmed no serious injuries had been reported following the incident. Police and paramedics rushed to the scene of the crash. The motorway was shut in both directions for just over an hour, with lanes one and two reopening at around 1.30pm to traffic.
Overnight repairs took place and the road fully reopened at around 3.30am on Saturday morning, the spokesperson added. Devon and Cornwall Police and South West Ambulance Service were approached for comment.
