Three people have sustained serious injuries after their van rolled over in Grass Patch on Tuesday morning, with the remaining five passengers treated for minor injuries.
Emergency Services were called to the rollover on Kent Road, 78 kilometres north of Esperance, at around 8.25am Tuesday, November 28, after the vehicle lost traction on an unsealed road.
The passengers of the Toyato Hiace were on their way to Lucky Bay when the crash occurred.
The driver sustained fractures to his spine, scapular and eye socket, and a passenger with a suspected fractured pelvis were both taken to Esperance Regional Hospital.
Another passenger with a spinal injury may be flown to a Perth Hospital by the Royal Flying Doctor Service later today.
St John Ambulance community paramedic Paul Gaughan told Esperance Police all eight occupants had been treated for various injuries and shock.
Police are investigating whether speed was a factor of the crash but have said no alcohol was involved.
Esperance Police senior sergeant Richard Moore said all motorists should drive to the road conditions.
“If you are unsure of the condition of unsealed roads take extra care and slow down to speed you can safely drive your vehicle,” he said.
Police said the nationality of the occupants would not be released until the families of those involved had been notified.
