Driver forced to jump from burning car after engine fault

A driver was forced to flee her burning car when the Toyota Corolla erupted in flames during Adelaide's morning commute.

The car ignited on Marion Road, South Plympton just after 7.30am, with the woman forced to pull over into a carpark and jump clear as witnesses rushed over to check on her and help try and put the fire out.

"The flames grew and the fire got bigger and a couple of popped tyres with the young fella hanging over the fence trying to put it out, was a bit scary," witness Steve Troy told 9News.

Firefighters arrived a short time later and extinguished the flames.

An engine fault is believed to be the cause of the fire and the car was completely destroyed.
