A teenage motorcyclist has died following a collision on the A3102 between Calne and Hilmarton last week.
Police were called to the collision involving the motorcyclist and two vehicles just after 5.45pm on Thursday.
The motorcyclist, an 18-year-old man from Calne, was riding a Honda 125 motorcycle when he collided with a grey Vauxhall Astra while overtaking a white Vauxhall Astra van.
The motorcyclist sustained serious injuries to his head and spine and was taken to Southmead Hospital in Bristol by the Great Western Air Ambulance but died on Saturday.
Next of kin have been informed but formal identification has not yet taken place.
A policespokesman said: "A post-mortem will be carried out in due course and a file will be prepared on behalf of H M Coroner for Wiltshire.
"Our thoughts are with the family and friends at this difficult time."
Anyone who witnessed the collision should call PC Leighton Williams, from the Tri-Force Roads Policing Unit, on 101 or Crimestoppers on 0800 555 111 where information can be left anonymously if preferred.
