A man deliberately drove into his 'friend' after an argument over a cigarette which left the victim with life-changing injuries.
Louis Timms, of Sutton Road, Kirkby-in-Ashfield, admitted causing serious injury by dangerous driving on second day of the trial at Nottingham Crown Court.
The impact of the vehicle flung the victim into the air before they landed in a hedge.
The victim was taken to hospital in a critical condition and was put into a medically induced come with swelling to the brain. He also suffered a fractured eye socket and a broken leg.
He had surgery on his right eye socket and lost vision in his right eye. Metal plates were also fitted to his cheekbone and leg.
25-year-old Timms was sentenced to four-and-a-half years in prison and was banned from driving for 75 months for the incident that happened on 19 February.
It happened after the victim lit a cigarette in Timms' Citroen Berlingo, sending him into a rage. He got out of the van and tried to attack the man but he run off, so Timms got back in the vehicle and drove towards him.
CCTV shows the man initially managed to step out of the way. Timms then carried out a U-turn and drove back on the wrong side of the road before striking the man with the van and speeding off towards Kirkby-in-Ashfield town centre.
Officer in the case, PC Mark Dickson, of Nottinghamshire Police, said:
