Another driver, Dean Norris, saw the Focus approaching him in the opposing lane and said it momentarily left the road surface due to the dip on the road and formed the impression it was travelling at excessive speed.
“He saw the vehicle land back on the road surface before it lost control as it passed him,” said the prosecutor.
Mr Norris turned back to offer help and went to the Focus, but could not find any signs of life from the three men inside the vehicle.
When police arrived Colville confirmed she was the driver and said her boyfriend Reece Williams was in the car along with her friends.
Mr Williams had sustained blunt-force injuries to his head, chest, abdomen and limbs in the crash.
Mr Soden suffered multiple injuries to his head, neck, chest abdomen and pelvis and Mr Page died from multiple blunt-force head and neck injuries.
The court heard that data recovered from the car showed its speed increased greatly on the approach to the crash scene, hitting a maximum speed of 92.6mph prior to a bend and continuing through the bend at speeds in excess of 85mph.
Collision investigators said the crash occurred because the driver was “driving at significantly excessive speed for the road layout and approaching hazards of which she was warned of”.
The court heard that a section of the road before the crash site has a series of peaks and troughs with a warning sign in place to alert drivers.
Defence solicitor advocate Gordon Martin KC told the court that Colville, who suffered a broken shoulder and ribs, has not driven since the incident.
