Graham Slinn had dismounted and was walking across the A57 near Todwick, South Yorkshire, when he was hit by a Volkswagen Golf driven by Cain Byrne, 20, and thrown at least 15ft in the air, Sheffield Crown Court heard.
Byrne, of Chesterfield, Derbyshire, sped off after the collision on 4 April.
Witnesses said Byrne, who has never held a driving licence, made no attempt to stop at the crossing and was travelling well over the 50mph limit, with one estimating his speed at 80mph.
Byrne admitted causing the pensioner’s death by dangerous driving at a previous hearing.
On Monday, Byrne was sentenced to 11 years and six months’ detention in a young offenders institution, with an extended licence period of five years.
He was also banned from driving for 17 years and eight months.
