Horrific footage shows how a lorry driver ploughed into stationary traffic after he fell asleep at the wheel.
Mariusz Wlazlo, 47, was jailed after he drove his fully-laden HGV into two cars at 43mph on a busy motorway.
The Polo driver, a woman in her 50s, spent weeks in hospital where she was treated for broken ribs and fractures to vertebrae.
The Toyota driver also had to be treated in hospital for back and neck pain.
Police released footage of the crash to show the dangers of not paying attention on the road.
At the scene, Wlazlo told police: ‘I think I went to sleep for a moment.
‘I can’t explain as I don’t remember.
‘It was like a dream.’
Dashcam footage from the lorry and from another nearby car shows how Wlazlo, who was an agency driver behind the wheel of an Eddie Stobart vehicle at the time, was speeding up at the time of the impact.
Wlazlo was in a 40mph zone of the southbound M6 between junction 8 and junction 7, near Great Barr, Birmingham, at the time of impact.
The M6 southbound was closed for 90 minutes after the crash, which happened at around 9.40pm on March 15 this year.
Wlazlo, who held a full, clean UK driving licence and had no record of motoring offences in his home country of Poland, admitted causing serious injury by dangerous driving and was jailed for 16 months at Wolverhampton Crown Court on Wednesday.
Wkazlo, of Speke, Liverpool, was also banned from driving for three years and eight months, and ordered to take an extended re-test.
PC Gareth Phillips, of the Central Motorway Police Group, said: ‘The collision has had a devastating impact on the victim in the Polo.
‘Although she has made a physical recovery, she now feels unable to drive on the motorway.
‘It shows just how important it is to keep fully focussed on the road and surrounding conditions, and to always abide by the speed limit as displayed on gantry signs.
