A young woman who spent three months in jail for almost killing her sister and two friends has opened up about the 'stupid mistake' she made that landed her behind bars. 

Caitlin Peacock was with two of her best friends and her sister on November 6, 2018 when she started 'driving recklessly, using both sides of the road, cutting corners and speeding'.

The mistake almost cost her sister her life and landed the 21-year-old in Townsville Women's Correctional Centre, for three months, where she spent Christmas, New Years Eve, her mum's birthday and her one year anniversary with her partner. 

'I missed out on the important things,' she said.

'But it was a good experience for someone my age and for someone like me to go through all that.'

Ms Peacock wasn't drunk at the time of the crash, but was 'young and dumb' and thought she was having fun.

Moments later, she rounded a corner and found herself heading down a steep hill toward an embankment and realised she couldn't slow the car down. 

The car plunged straight off the three-metre cliff and wound up crumpled in dense bushland.

Ms Peacock said she passed out but woke up moments later to the sound of a seatbelt unbuckling. 

Ms Peacock and her sister (pictured together) were transported to hospital 'side by side'. She said all she wanted in that moment was for her sister to be okay

She managed to climb out of the drivers' side door, taking her phone with her as she made the excruciating climb back up the embankment. 

To her horror, she realised her sister hadn't followed her.

'I laid on the road realising I had made a huge mistake and called 000,' she said.

She walked the operator through the events of the night, explaining that she was struggling to walk, one of her passengers appeared to have a broken leg, and worst of all, her sister was unconscious. 

'I thought I killed her,' Ms Peacock admitted. 'My sister was unresponsive and trapped in the car for some time.

'I was hysterical.' 

Several friends in another car behind them went to find help and eventually ambulances and concerned onlookers started arriving.  

Ms Peacock and her sister were transported to hospital 'side by side', but she was released when doctors realised she hadn't sustained any serious injuries.

Looking back, she said she agrees the judge made the right decision in sending her to jail. Ms Peacock shared her story hoping to teach young drivers a lesson

'All I wanted was for everyone to be okay... I was discharged the very next day with nothing but a few cuts and bruises,' she said.

Later testing revealed she had fractures in both of her knees. 

Police took samples of Ms Peacock's saliva for a drug and alcohol test, which both returned negative readings.  

Her sister spent a week in hospital recovering because doctors were concerned about her memory and brain after she had been knocked unconscious.

Another passenger spent several weeks in hospital because he broke his leg, while the final passenger 'couldn't walk properly for weeks'.  

In the months following the accident, Ms Peacock's sister and friends were called to Cairns Police Station to give evidence about what happened.

'I told each of them not to lie for me, to tell the truth, because whatever happened I knew I deserved,' she said. 

'I've never been in trouble with the police before. I'd never even had a parking or speeding ticket... They ended up
