The following road sign remains valid:

- Correct answer: Until the nearest intersection or until a road sign that cancels it or until a “vehicle parking” sign.
- Until a speed limit sign.
- Until the nearest intersection with traffic lights.
- Until a bus station sign.
Why this is the answer
The correct answer in the official bank: Until the nearest intersection or until a road sign that cancels it or until a “vehicle parking” sign.
The sign is valid until the nearest intersection, and the intersection does not have to have traffic lights. It also ends earlier if a sign cancelling it or a "vehicle parking" sign is posted. A speed limit sign or a bus station sign does not set the end of its validity.
