A couple who were involved in a fatal crash at an accident-prone intersection in Central West New South Wales have spoken out about the incident that claimed the life of a teenager.

Stephen and Sue Doyle's lives were changed in an instant while they were waiting to turn right at an intersection on the busy Mitchell Highway, to enter Thompson Road.

"We were hit from behind, by the young [person] driving the ute, and that impact rendered us immobile and sort of pushed us over the line," Mrs Doyle said.

The two occupants of the ute — one of them John Keegan, 15 — walked up to the couple to make sure they were OK.

"I was talking to them, both on my right side, through the door and the younger boy [John Keegan] went round the other side," Mr Doyle said.

"Sue said, 'Look out! Truck!' with an expletive in the middle, then bang.

Mrs Doyle said she blacked out before the truck crashed into them.

"The truck coming then hit the boy, then hit us … and pushed us up the road a bit," she said.

Central West police said the teenager was killed when a truck hit both vehicles.

The Doyles, both in their 70s, spent time in hospital recovering, but since the accident, neither has been cleared to drive.

Mick Ward heard the bang at his nearby property about 7:00pm and went down to the site to provide help.

"It was pretty traumatic," Mr Ward said. "I saw the young driver, he was over on the grass, just blubbering and trying to ring for help.

"The truck driver was in a mess, he was shivering. I put a coat on him and he went and got the blanket and gave it to us and we put it on the young fella."

Fatality waiting to happen

Mr Ward has been living near the intersection for about 40 years and said he had witnessed "no less than nine accidents" there.

He said local residents, including Cooey Tancred, have been advocating for upgrades to the intersection for years.

Mrs Tancred lives on Thompson Road and was also involved in a collision when her car was hit from behind and into oncoming traffic, narrowly missing being hit by a semi-trailer.

She said that, after her accident, she went to the police station to find they had no record of the incident because "an ambulance wasn't called, nobody was charged and parties exchanged details".

Mrs Tancred also said police told her that, if an accident fits a set of criteria, it can still take nine to 12 months for Transport for NSW to be notified.

Member for Orange, Philip Donato, said he had been calling on the state government and Transport for NSW for safety improvements for months.

"Had they taken these concerns seriously, perhaps this fatality would've been avoided," Mr Donato said.

Highlighting the issues with the current reporting method, Mr Donato said he received a letter last November from parliamentary secretary Christopher Gulaptis on behalf of the Minister for Customer Service, Paul Toole, stating only one crash had been recorded at the location in the past five years.

Mr Donato said he still hasn't heard from Minister Toole about the issue.

Orange police said investigations by the Metropolitan Crash Unit were ongoing.
