The police are appealing for witnesses after an octogenarian from Marazion crashed into a hedge on the A30 and died.
The 84-year-old man had been driving his silver Mazda 323 towards St Erth when it left the road at the Newtown roundabout, Long Rock just after 6pm on December 28.
He was found unconscious and taken to the Royal Cornwall Hospital at Treliske where he was pronounced dead.
His next of kin have been informed.
The road was closed for two-and-a-half hours while police examined the scene.
Police officers have launched an investigation and are appealing to anyone who witnessed the collision. They would particularly like to speak to a cyclist who stopped at the scene but left before police arrived.
Anyone with any information is urged to contact the Camborne Serious Collisions Unit on the non-emergency number 101, quoting reference number 510 of 28/12/12.
