Ryan Paul Mackay, of Clifton Mill Barn, Station Road, Salwick, near Preston, ran over his 42-year-old victim’s foot while behind the wheel of a Mini Cooper in Trinity Close, Freckleton.
The 22-year-old was due to face a trial, but during a hearing before Judge Graham Knowles QC, he pleaded guilty to a charge of causing serious injury while driving a car dangerously.
The court was previously told police were called around 12.45pm after reports of a collision on October 8 last year.
At the time police said they believed the victim had been driving when he passed another vehicle and urged the driver to slow down.
