A single mother who was punched in the face by a man during a terrifying road rage incident has been sentenced to community service for instigating the confrontation.

Footage of the incident shows Bianca Lee Sams, 22, throwing nails at Clint Matthew Pollard's brand new ute, prompting him to punch her in broad daylight at a Lake Munmorah intersection, 50kms north of the Central Coast, in July last year.

Sams was sentenced to a total of 360 hours of community service when she fronted Wyong Local Court on Monday for intentionally risking people's safety and damaging property after she threw the nails and a metal chisel.

She will only have to serve 140 hours because the sentences were concurrent.

The chisel damaged multiple panels and the driver's side mirror of Pollard's car.

The 22-year-old single mother was also fined $500 for hanging out of her friend's car to throw the nails, The Daily Telegraph reported.

In the footage, which has since gone viral, Sams could be seen laughing as she hurled nails towards his ute.

When the vehicles came to a stop, Sams exited the vehicle and stood with her arms crossed as Pollard, the driver of the ute behind her, approached.

Pollard, 42, was then seen unleashing a sickening punch that jolted Sams' head backwards and into the car door window.

Sams' solicitor entered guilty pleas to intentionally throwing objects at a vehicle risking the occupant's safety, having part of her body outside the window and two counts of damaging property (pictured is injury Sams sustained)

Sams' friend Taylor Bembridge, who was driving, had her five-month-old baby in the back seat of the Ford ute at the time of the terrifying incident.

Bembridge pleaded guilty to reckless driving after she was captured in the footage trying to reverse into Pollard.

Bembridge later bragged about the assault on social media.

Her license was suspended for five months.

Pollard appeared in Wyong Local Court in March where he pleaded guilty to the assault.

He was given a three-year good behaviour bond and fined $900.
