AN EARLY morning ride soon turned traumatic for a group of motorcyclists when the lead rider and an oncoming four-wheel drive collided.
In what witnesses described as a "domino effect", a further two bikes became involved in the crash.
Police said the convoy of eight motorcyclists were rounding a bend on the Gladstone-Monto Rd, 17km from Calliope, when the collision happened between 10.30am and 11am yesterday.
The female driver of the car and at least four riders were involved, some being transported to hospitals in the area.
Emergency services were quick to respond, with police, ambulance and fire crews working to get patients to safety and clear the road.
Two helicopters airlifted patients to Bundaberg and Rockhampton.
Drivers who were stopped early on when the collision occurred assisted by telling other members of the public in their vehicles to turn around as the road was closed.
An RACQ CareFlight Rescue helicopter transported a Gladstone husband and wife suffering from abrasions and possible fractures to Bundaberg hospital.
They both travelled in a serious but stable condition.
A man was airlifted to Rockhampton Hospital with gross trauma by another helicopter rescue provider.
An ambulance transported a 48-year old man to Gladstone Hospital. He was later discharged. Other patients were transported privately.
The road was reopened at 4pm.
