Until where does the following road sign remain valid?

- Correct answer: Until the next intersection.
- Until an “entrance to an urban road” road sign.
- Until 150 meters following the place of the sign.
- Until the nearest pedestrian crossing.
Why this is the answer
The correct answer in the official bank: Until the next intersection.
This sign marks a lane on the road set aside for bicycles. Signs that regulate traffic on a road section or lane generally apply only up to the next intersection; after it, a new sign is needed for the rule to continue. A pedestrian crossing or a fixed distance does not end its validity.
