Police had earlier believed two vehicles were involved in the collision.
The man remains in a critical but stable condition in hospital. His next of kin are aware.
Kent Fire and Rescue Service and South East Coast Ambulance Service also attended the incident, and remain at the scene, the force said.

The M20 and the A227 remain closed while emergency services deal with the incident, with motorists advised to use alternative routes.
Images and footage shared on social media showed a tractor upside down with railings bent in the central reservation.
Large queues of vehicles were forming on either side of the bridge.

South East Coast Ambulance Service said it was called to reports of a collision involving a tractor and a lorry on the bridge at around 11.20am.
Multiple crews, a critical care paramedic and the local air ambulance were sent to the scene.
The driver of the tractor was airlifted to King’s College Hospital in London, the service said.
National Highways said the M20 was expected to be closed in both directions between junctions one and three into Monday evening for emergency repairs and resurfacing, after damaged caused from the collision and a subsequent fuel spillage.
