Sydney mum charged over 'large burnout' outside a doughnut shop with her baby in the backseat

An Australian mother has been charged after police caught her doing a "large burnout" in the carpark of a Sydney doughnut shop with her baby in the back.

The 23-year-old, from the Sydney suburb of Liverpool, was performing the burnout in her illegally modified Holden Calais outside a Krispy Kreme shop with her 10-month-old in the back. 

Highway Patrol officers were on their routine patrol when they saw the burnout. They also found the woman was not carrying her P2 license and was not displaying her P-plates on the vehicle (the equivalent of an NZ restricted license).

The mum apologised for her behaviour in an interview with 9 News after her arrest on Friday, saying "I just happened to go over a speed hump and put my foot down".

"It was a very stupid move," said the woman's partner, who was also in the car. 

"We are very, very sorry, and we want every young person out there to take care on the road."

The car's six-cylinder engine had been replaced by a modified V8 engine, and had only a partial exhaust system fitted, 7 News reports.

The mum has been issued a Field Court Attendance Notice after being charged with an aggravated burnout and is due to appear at Liverpool Local Court on July 17.

She has been fined a total of AU$936 (NZ$977) for driving a prohibited vehicle, for not displaying P-plates and for not carrying her driver's license.

If found guilty, the woman could face possible jail time and a further AU$3300 in fines (NZ$3444), reports 7 News.

The Holden has been issued with a major grounded vehicle defect and the woman's license has been suspended.

Police reportedly submitted a child-at-risk report to Family and Community Services regarding the incident and the 10-month-old.
