Police are searching for two men and a woman who miraculously survived after rolling their car several times before it burst into flames while on the freeway on Monday night.
Police said the Lexus RX 350 SUV was traveling south on the freeway when it collided with an Audi S3 traveling in the same direction.
The force of the crash caused the Lexus to flip before it hit a metal barrier and burst into flames in the right hand lane.
The incident on the Mitchell Freeway, near the Vincent Street off-ramp in Leederville, sparked peak hour chaos about 6.10pm.
The flaming wreck caused several southbound lanes to be blocked while firefighters battled the blaze.
The driver of the Lexus and his two passengers, who were lucky to survive the horror crash, fled the fiery wreck on foot.
The driver of the Audi was uninjured.
WA Upper House MP Wilson Tucker told The West Australian that he saw the car roll “about 10 times”.
“I just witnessed a terrible accident southbound on the Freeway,” he said.
“A car in the opposite lane was airborne and rolled about 10 times.
“To say I hope everyone is okay isn’t realistic, I just hope everyone survived.”
Police are still trying to locate the male driver and his passengers, a man and a woman, and have called for witnesses to phone Crime Stoppers on 1800 333 000 or report the information online at crimestopperswa.com.au
