What applies from this traffic sign onwards?

This sign marks the beginning of a built-up area in Germany. From this point onwards, specific traffic rules apply:

1. The use of the horn to signal your intention to overtake is prohibited. This reduces noise pollution in residential and built-up areas.
2. Parking cars may be safely marked with parking lights (also called sidelights). This means when you park in such areas, it is allowed to use parking lights to make your vehicle visible.
3. Driving with parking lights alone in the dark is not allowed. You must use proper headlights for visibility and safety.

These rules help ensure safety and reduce disturbances inside built-up areas. Your choice to select the first two options is correct because the sign signals these particular local regulations.
