A 21-year-old man has admitted a horrific road-rage attack where he tailgated a female student paramedic for 10 kilometres before punching her in the face, leaving her bruised, bloodied and traumatised.

"I'm not afraid to hit a girl," Joshua Burke said before the bashing that left the young woman with a fractured eye socket.

Burke could be jailed for up to five years after pleading guilty on Tuesday to a string of offences linked to the road rage incident.

The victim, Erin, who doesn't want her surname made public, was 23 at the time of the attack on November 1, 2018.
