A road closure is in place on the A30 at Loggans Moor, Hayle following a two vehicle road traffic accident this afternoon.
Emergency crews were called at about 4.40pm and are still on scene, but police say there are no reports of injuries at this time.
Early reports were that someone was trapped, but this appears not to be the case.
It is understood a car and a 4x4 travelling in opposite directions collided. Debris was left strewn across the road.
An eye witness who arrived shortly after the incident said they spotted a car on the embankment and a group of people trying to assist and a person he believed to be the driver sitting on the verge.
"One of the men suddenly started running away as the car started sliding back down towards the road," he said.
Diversions are in place and expected to remain so for at least an hour.
