Police are investigating whether an 82-year-old man who died after slamming his car head first into oncoming traffic last night suffered a heart attack prior to the crash.
The man's blue Mercedes Benz was travelling west on Great Eastern Highway when it entered the Epsom Avenue intersection about 6.30pm.
The Mercedes Benz then travelled to the wrong side of the road and collided head on with a Holden Commodore being driven by a 34-year-old man.
The Holden driver and his occupants escaped without injury but the 82-year-old sustained critical injuries.
He was taken to Royal Perth Hospital but died a short time later.
Major Crash investigators are asking anyone who saw the crash or the vehicles prior to the collision to call Crime Stoppers on 1800 333 000.
