A carpenter who helped extinguish a fire at a horror crash at Jandakot yesterday has described the moment a four-wheel-drive collided head-on with an oncoming car.
Both drivers were killed.
Glen Wellington, 30, was travelling about 50m behind a Nissan Pathfinder on the eastbound lanes of the Roe Highway in Jandakot about 6am yesterday when he saw what looked like "a bomb going off".
"It was a nice clear morning and all of sudden, there was debris and dust everywhere," Mr Wellington said.
The Nissan, being driven by a 28-year-old Rockingham man, collided with a silver Toyota Avensis station wagon, driven by a 56-year-old Beeliar man, after it crossed the 5m bush median strip from the right-hand westbound lane. The speed limit in the area is 100km/h.
"I saw a lot of red brake lights flashing and then the (Nissan) tilt up in the air, then flip over and roll onto its side," Mr Wellington said.
"I jumped out of the car . . . we were there within 10 seconds of the crash. The car was still rocking when we ran over and the fire flamed up straight away."
Mr Wellington ran back to his black BMW and grabbed a fire extinguisher before rushing back and putting out the flames.
The impact of the crash is believed to have killed the driver of the Nissan instantly.
"He didn't stand a chance," Mr Wellington said. "There was no way he could have avoided that. There's no way he could have swerved to help himself."
He said once the passers-by who had stopped to help realised that they could not help the younger driver, they concentrated their attention on the Toyota driver who appeared to still be breathing.
"He was semiconscious but wasn't well," Mr Wellington said.
"We were trying our best to talk to him and keep him as calm as we could."
The man died before paramedics arrived.
Sgt David Magorian from the major crash squad said it was impossible to determine exactly how fast both vehicles were travelling but the extensive damage indicated it would have been "quite a high impact".He said the police investigation would focus on why the Toyota swerved into median strip embankment.
