Christopher Dixon, 27, of Owen Place, and Gregory Grant, 33, of Vincent Road, were both found guilty of conspiring to pervert the course of justice following a trial at Aylesbury Crown Court.
Dixon was today (Friday) sentenced at Amersham Crown Court to 27 months’ imprisonment and Grant was sentenced to 21 months.
It follows the death of Mark Camber, 49, on April 16, 2012.
At around 11.50pm Dixon was driving his van on Nash Lee Road in Terrick, near Aylesbury, when he hit Mr Camber. Grant was the front passenger at the time.
Mr Camber died at the scene.
Following the collision, the pair left Mr Camber at the roadside and drove to Waddesdon so the incident would not be linked to them and the van could be repaired in the morning.
However, they were convinced by other people to report the incident and went to a police station early the next morning.
Investigating officer, PC Naomi Hames, said: “We are pleased with the sentence here today.
“Following the collision, Dixon and Grant left Mr Camber at the side of the road, knowing full well what they had done.
“I want to take this opportunity to pay tribute to Mr Camber’s family and commend their dignity and strength in the most difficult of circumstances.
“Hopefully the sentence today will go some way to helping them take the next step with their lives.”
