A crash at Mudgeeraba has caused some havoc on the M1 this morning.
A car flipped in the northbound lanes at 9:20, after apparently colliding with a truck.
A woman in her 30s was taken to hospital in a stable condition.
Her vehicle was loaded onto a tow truck and traffic started flowing freely again about half an hour after the incident, however it caused about 9km of gridlock that was expected to take quite a while to clear.
Another patient assessed at the scene declined transport to hospital.
