Until where do the following road signs remain valid?

- Until the nearest traffic light, provided that the light is green.
- Until the nearest bus station.
- The validity of the sign expires when approaching a densely populated area.
- Correct answer: Until the nearest junction or until another “speed limit” or “end of speed limit” sign is placed.
Why this is the answer
The correct answer in the official bank: Until the nearest junction or until another “speed limit” or “end of speed limit” sign is placed.
A sign that sets a maximum speed, whether a regular or an electronic one, applies to the section of road after it. It stops being valid at the nearest junction, or when another sign sets a different speed, or when a sign marks the end of a special speed limit section. So after the junction the speed set by the sign no longer applies, unless the sign is placed again.
