A motorcycle passenger was taken to hospital with a broken arm and leg injuries after colliding with a car.
Having receiving treatment from paramedics, the man, in his 20s, was taken to Medway Maritime Hospital in Gillingham, as a priority with a broken arm and suspected broken ankle.
The motorcycle passenger was treated at the scene in Watling Street near Bean before being taken to Medway Maritime Hospital.
The incident happened on Wednesday on the coast bound A2 slip road leading from Bluewater, at the rear of A2 Car Breakers.
The motorcycle passenger has since been transferred to King's College Hospital in London, for further treatment.
Three ambulances arrived at the scene at the Merry Chest Cafe at 2.05pm.
Police were also in attendance.
Witnesses say the incident is believed to have happened when a car pulled in front of the motorbike.
The driver of the motorcycle, a man, was not seriously injured.
Before the paramedics arrived the men were attended to by workers from the nearby car wash.
A spokesman for South East Coast ambulance thanked them for their help.
He said: “Any help we receive before we get to the scene is very useful, we’d like to say thank you and well done to those involved.”
