A woman has been charged with six offences including dangerous and negligent driving over a fatal crash in the Illawarra region last month.
Emergency services were called to reports of a collision on the M1 Princes Highway about 7.15pm on Friday, March 5.
Four people were trapped when the Holden Statesman sedan they were travelling in hit a median strip and a tree after a collision with a Nissan Juke, which had also been travelling south, near the Masters Road off-ramp at Mount St Thomas.
The 47-year-old female driver of the Holden Statesman died at the scene.
Her three passengers - a 15-year-old girl and two boys, aged five and 10 - were airlifted to The Children's Hospital at Westmead suffering serious injuries.
The female Nissan driver, then 29 years old, and her passenger, a 32-year-old man, were uninjured. The woman was taken to hospital for mandatory blood and urine testing.
Officers from the Southern Region Crash Investigation Unit led inquiries into the crash. As a result, the now 30-year-old Nissan driver was given a Court Attendance Notice for six offences on Saturday, April 10.
The charges include dangerous driving occasioning death; dangerous driving occasioning grievous bodily harm; negligent driving occasioning death, and grievous bodily harm; and two counts of causing bodily harm by misconduct while in charge of motor vehicle.
The Lake Heights woman is due to appear at Wollongong Local Court on Tuesday, July 20.
