A man is fighting for his life after crashing into a parked car this morning.
The 73-year-old driver slammed into a stationary truck on Birralee Road in Regency Park, Adelaide at 7.30am.
His car became stuck under the truck before he was freed and rushed to the Royal Adelaide Hospital.
"He was unconscious and was in a critical condition and I think he has sustained some catastrophic head injuries," paramedic Nathan Park said.
Police are investigating if the man from Tennyson suffered from a medical episode before the crash.
