When his car rolled over, the 87-year-old driver was so badly injured on Rügen that he had to be flown to the clinic in the rescue helicopter.
As the police announced on Saturday, the man's car came off the road in a left curve on the road between Gustow and Poseritz in the early afternoon for unknown reasons.
Bergen - The car hit a tree, rolled over several times and landed on the roof.
When the police arrived, the seriously injured man was already on the way to the clinic, it said.
The vehicle was damaged by around 10,000 euros, so the road had to be temporarily closed.
