- One-way lane for bicycles.
- End of bicycle lane.
Why this is the answer
The correct answer in the official bank: Caution, bicycle traffic ahead.
This sign warns of bicycle traffic ahead. The symbol inside it shows what to watch out for, here cyclists on the road. Slow down, pay more attention and keep a safe distance from cyclists. The sign does not mark a path or a lane for bicycles, so it is not a path for bicycles only, a one-way lane for bicycles or the end of a bicycle lane.
