Shocking footage shows the moment a drink-driver crashed his van after swerving across a busy motorway - before he was found fast asleep behind the wheel.
Jamie Barrett, 30, was spotted driving dangerously as he headed north along the M1 in Nottinghamshire on September 14 this year.
A concerned witness contacted police to describe his erratic driving as if he was "shaking his steering wheel quickly from left to right."
Dash-cam footage captured Barrett veering all the way from lanes one to four as he recklessly drove in his black Ford fan between junctions 25 and 26.
