William Cameron pleaded guilty to four charges including flight from police and impaired driving causing bodily harm.
Court was told Leah Cobetto, 22, was injured so badly she had to have one of her legs amputated.
Cobetto read a tearful victim impact statement during sentencing on Monday, saying she feels like she had to start her life over, re-learning how to walk, swim and even sleep.
She also said she has to use a walker or a wheelchair wherever she goes, and suffers "excruciating" phantom pain from her lost limb.
Judge J.B. Mitchell called Cameron's previous criminal record "pathetic" for someone his age and said his flight from police on the night of Sept. 23 showed disrespect for people's lives.
He also said the only reason Cameron's chase ended was because the vehicle he had stolen earlier in the day seized up, but if it hadn't, other innocent people could have been affected.
Cameron will also face a seven-year driving prohibition and 10-year weapons ban once he is released.
