Police are trying to identify this dozy van driver who was filmed while appearing to be asleep at the wheel.
A shocking 12-second clip of the idiot was posted on Facebook and shows him sitting back with his eyes closed and arms folded as his van travels at speed.
A smirking workmate can be seen holding the steering wheel with one hand as cars whizz past on the opposite carriageway.
The footage – captioned “I don’t drive but I’m pretty certain this isn’t legal or safe” – was uploaded to the site on Monday.
The prank has been condemned by road safety campaigners.
Neil Greig, of the Institute of Advanced Motorists, said: “This is of course illegal and is simply asking for trouble – both on the road and from the police who will also see this video.
“The selfishness of these people astounds me – how could they live with themselves if they killed an innocent passerby, just for the sake of trending on social media for a few hours?”
A spokeswoman for road safety charity Brake added: “Falling asleep at the wheel is no joking matter – at least 300 people die on our roads every year as a result of tired driving, tearing apart families and communities across the country.
“Drivers who fail to stop when they’re tired, or mess about at the wheel and don’t pay attention, are gambling with the lives of everyone on the road.”
The footage was posted by a user from Carluke, South Lanarkshire but it is unclear when or where it was taken.
A spokeswoman for Police Scotland said: “This type of behaviour not only puts these individuals at risk but also other road users.
“Whether it is a prank or not what they are doing is extremely dangerous.
“I would appeal for anyone who can identify them to contact police.”
