The road is closed both ways between Fairseat Lane and Vigo Road, but residents trying to access their homes from the A227 will be allowed through by officers at the scene.
The air ambulance landed nearby, and the victim - thought to have been in the car at the time of the crash - has been taken to Darent Valley Hospital in a life-threatening condition.
