A driver and three passengers are on the run after allegedly causing a five-car crash that left eight people in hospital on the Gold Coast.
Police said a black Mercedes sedan was travelling south on the Gold Coast Highway in Miami when it collided with a Mitsubishi SUV.
The Mitsubishi was forced into the back of another car, which went on to hit two more vehicles.
The driver and three passengers got out of the Mercedes and ran away.
Paramedics arrived at the scene and assessed 17 people before eight were taken to hospital.
Queensland Ambulance Service said three were seriously injured, including a man in his 30s with a head injury and a woman in her 20s with leg injuries.
Police Acting Chief Superintendent Chris Stream said the driver of the Mercedes was allegedly speeding.
"I'm told by the emergency responders that attended that accident scene it was a miracle no one was fatally injured," he told reporters on Sunday.
Police Forensic Crash Unit investigators have urged the Mercedes driver and passengers or any witnesses to contact them, saying reports can be anonymous.
