The 17-year-old was behind the wheel in a shopping centre car park at Dubbo when the woman fell off the moving vehicle and hit the ground.

He pleaded guilty to driving in a manner dangerous to the public, being an unaccompanied learner, not displaying 'L' plates, driving with a passenger on part of the vehicle not permitted and driving a vehicle without clear view.

Magistrate Andrew Eckhold imposed a two-year good behaviour bond without proceeding to conviction and admonished the 17-year-old for his behaviour.

"You are lucky you did not kill your friend," Mr Eckhold said.

"Your view was obstructed.

"You were driving too fast.

"This is what people fear young men will do."

In sentencing the teen the magistrate noted it was the youth's first time before the court, that he had pleaded guilty, had completed a traffic offender's program and was of prior good character.

The offences occurred in the Orana Mall car park about 2am on November 30.

The teen got into the driver's seat of a car, and on the bonnet at the base of the windscreen was a 25-year-old woman, the person in charge of the vehicle, court documents show.

The woman later told police she willingly stayed on the bonnet, court documents show.

The L-plater had a stint of driving, during which time he braked harshly, causing the woman to roll off, land on her feet and stumble.

She got back on the bonnet and the behaviour continued, and the car was travelling at moderate speed and turning left when the woman slid off the driver's side bonnet.

Her head impacted the ground, causing a gash to the back of her head and she went to hospital.

In sentencing submissions the defence said there had been a group of young people, the teen had asked the woman to get off the vehicle and "peer pressure" had been a factor.

The solicitor said the teen had told her he now understood after completing the traffic offenders program the responsibility someone took on when they were in the driver's seat.
