Police have charged the 21-year-old woman shown in shocking video footage being punched in the face during a road rage incident on the NSW Central Coast.

The charges come after the footage was shared widely on social media showing a man leave his car and approach a woman, identified as Bianca Sams, and attacking her.

Police say two cars were travelling along the Pacific Highway in Lake Munmorah on Monday when they stopped at an intersection.

An argument then broke out between the woman and man.

On Thursday, Sams attended Wyong Police Station where police laid a raft of charges including malicious damage, being armed with intent to commit an indictable offence, intentionally throwing an object at a vehicle and having part of her body outside the car window.

The 41-year-old man was on Wednesday charged with assault occasioning actual bodily harm.

Warning. Graphic footage

Sams was granted conditional bail to appear at Wyong Local Court on September 6.

Dashcam footage posted on Facebook by witness Dwayne Pillidge on Monday made news across Australia and led to the charge of assault occasioning actual bodily harm being laid.

The unidentified man was granted conditional bail and will appear at Wyong Local Court on August 30.

The woman claimed on her own Facebook page that he had been tailgating the Mazda utility in which she was a passenger and she threw objects at him out of fear.

“I threw them because I had to … [it was] what I had to do to protect me and my friend,” she told the Nine Network.

“We were both scared, We didn’t know what to do. We tried swerving … and he kept following us.”
