A 16-year-old learner driver has described "the scariest moment of my life" after a speeding, drink-driver crashed into the back of his car and didn't stop to help the boy and his injured, unconscious mother.
The dangerous driver, Philip Abraham, who was 31 at the time of the crash, faced the ACT Magistrates Court on Monday for the start of his sentencing.
He pleaded guilty to aggravated dangerous driving, assaulting a frontline community service provider, not stopping to render assistance after an injury, and two counts of negligent driving occasioning actual bodily harm.
In June, Abraham was driving a grey Volkswagen Arteon sedan when he crashed into a Mitsubishi Lancer on Erindale Drive near the intersection with Charleston Crescent.
As a result of the impact, the Lancer, with a 16-year-old learner driver behind the wheel, hit a red jeep.
The boy and his mother, a passenger in the Lancer, were both taken to hospital.
On Monday, a prosecutor told the court Abraham had been driving at 210kmh with 100 per cent acceleration in the 2.4 seconds before crashing into the back of the car.
The posted speed limit on Erindale Drive is 80kmh.
He also returned a blood alcohol concentration reading of more than four times the legal limit.
In an impact statement read to the court, the 16-year-old victim described being in his car after the crash; his "mum knocked out next to me with a piece of glass in her forehead".
"The crash was the scariest moment of my life," he said.
"[Abraham] did not even stop to help us or check if we were OK."
The teenager told the court he was now terrified of driving, and the crash had "turned my whole life upside down".
"My grades have dropped, and I struggle to keep up because I am so tired and anxious all the time," he said.
"I worked so hard to get my first car, and it was destroyed in the crash."
The teenager's mother said in a statement that Abraham had "changed my life forever".
She described "constant pain" and anxiety and labelled his behaviour in not stopping to help her and her son "disgraceful".
"I'll never be able to work, move or have the same physical capabilities again."
Abraham's lawyer, Paul Edmonds, said his client offered his "profound" apology to the victims and their family.
He told the court Abraham had been sober for five months after going through a period of drinking alcohol daily, in response to a death in the family and being made redundant from his job.
The prosecutor said that when police tried to arrest Abraham after the crash, he placed an officer in a headlock and tried to resist being taken into custody.
Magistrate Robert Cook is set to hand down his sentence next month.
Abraham remains on bail.
