"It actually hosed down about half an hour before so there were quite deep puddles when arrived. It was a 75km/h advisory corner but I couldn't tell you how fast she was going."
Kaio said making the crash even more tragic was the fact she had friends travelling in a vehicle ahead of her at the time.
"They saw parts of what happened in the rear view mirror and turned around. She has lost control on the road and crossed over to the wrong side of the road and struck the oncoming truck."
The vehicle slid side-on with the driver's side taking the full impact.
"Her side, the driver's side, slid into the truck so she has taken the brunt of the sudden stop along with the car and has suffered some pretty horrific injuries and died at the scene."
He said it was a timely reminder for people to drive to the conditions especially given the dry conditions and the build up of oil and petrol left on the road.
"We are going to get showers on dry roads and the build-up of oils and petrol on the road make it pretty treacherous ... you just put a bit of water on them and it turns into a skating rink like it did today."
There were no other people on the road at the time, just the friends and the truck driver.
"There's no witnesses or no one else to glean anything from just a truck driver who is traumatised but uninjured."
