Taliah Patricia Read, 18, was spotted stopped at the roundabout at Fitzroy Street and Bultje Street in her green Toyota Camry when she was approached by police about 4am on January 1.

Police asked what the problem was with the vehicle, before asking her to move the car off the road.

She told them there was an issue with the radio.

As Read was selecting a gear, the car rolled back for a short distance before breaking, court documents revealed.

Shortly after, Read tried to move the car toward the curb on Fitzroy Street, however narrowly missed hitting the fixed traffic sign.

After police pulled up behind her and asked Read for her licence, she told them "I don't have my wallet and I have a learner licence", court documents said.

Police spotted a female passenger in the car, however she told police she wasn't a an authorised supervising driver and didn't have a licence either.

Despite a strong smell of alcohol on Read's breath, she told police she hadn't had alcohol in the last 15 minutes, but had been drinking.

She was taken to Dubbo Police Station, and returned a positive alcohol reading of 0.137.

In police facts, officers said while Read remained cooperative, due to her level of intoxication at times she appeared cheerful, giggling and smiling stating, "see I told you I was gonna get locked up tonight, I told ya," she said.

Later that morning, about 6.24am Read was again spotted by police driving south over the Serisier bridge.

When police pulled her over, there was nobody else in the car, and she emotionally told police "I've already been arrested and charged today".

After returning a positive roadside breath test, she was taken back to the police station again where breath analysis revealed a reading of 0.111.

Read told police she had consumed an unknown amount of blueberry vodka cruisers and Moscato at a home in Peak Hill earlier.

In Dubbo Local Court on Wednesday, Read pleaded guilty to two counts of mid-range drink driving, one count of a learner driver not accompanied by a supervising driver and one count of driving while suspended.

Police said they were concerned the incidents occurred within two hours of each other, and Read's actions were an "accident waiting to happen", court documents revealed.

Defence lawyer Molly Bland said Read had no criminal history, and requested the matter be adjourned so the 18-year-old could complete the traffic offenders program.

The matter will return to Dubbo Local Court on April 14 for sentencing.
