An 80-year-old woman was left with bleeding on the brain after a speeding driver who didn't want a BMW to overtake him crashed into her car during a road "race".
Jon Crowe had accelerated up to 60mph in a bid to stop the BMW overtaking his car on Station Road, Prudhoe, Northumberland, on May 12.
Newcastle Crown Court heard the 27-year-old, who had been taking cocaine, lost control of his vehicle and crashed into a Vauxhall Corsa being driven by the pensioner.
The victim's car was sent hurtling up an embankment at the side of the 30mph zone then rolled back down and came to rest on the road before she had to be cut out of the wreckage.
Crowe climbed out of his VW Golf, which landed on it roof as a result of the collision, and left the scene on foot.
He handed himself into the police the next day and made a full confession.
Prosecutor Paul Currer told the court: "The defendant said a BMW was behind him as he was travelling and that car appeared to be trying to overtake him.
"He was candid enough to tell the police he was determined to prevent this from happening.
"He accelerated hard, up to 60mph. The speed limit is 30."
The court heard the woman driver, who had been travelling home, had to be cut from her vehicle and spent two weeks in hospital with a broken wrist and finger, two fractured ribs and a head injury that caused bleeding on her brain.
She said in a victim statement she still has bruising more than seven months after the smash and has been told by a doctor it is likely to be permanent.
The pensioner still suffers pain from her injuries and remains "upset" about what happened.
She added: "I am unsure if I will ever drive again."
Crowe, of Cheviot View, Prudhoe, pleaded guilty to causing serious injury by dangerous driving, failing to stop after and accident and driving above the limit for cocaine.
Judge Stephen Earl sentenced him to 20 months behind bars with a three year driving ban and extended test requirement.
The judge told him: "If you embark on driving while under the influence of drugs at the level which you were and you decide to get into a race with someone else, causing this level of injury, you can expect an immediate custodial sentence from this court."
Judge Earl said it was "very lucky" that the victim was not killed in the collision.
Jonathan Devlin, defending, said Crowe has no relevant previous convictions, has a good job and positive references.
Mr Devlin said Crowe is "devastated" by the consequences of his actions that night.
