Passing motorists said the man told them he had been picking fruit from a tree next to the road when he was attacked by a swarm of bees, said spokesman Robert Mckenzie.
He then apparently ran to his car and drove for about one kilometre before his car left the road.
Passing motorists helped the man and called paramedics.
“When paramedics arrived on scene they found a car on the side of the road, but with little damage to the car.
“When they assessed the driver, an elderly man estimated to be in his late sixties, they found that he had sadly already passed away.”
Police were on the scene and would investigate the exact cause of the man’s death.
