Where is it forbidden to stop?

The selected combination of answers is correct because it aligns with German traffic regulations that prohibit stopping in specific areas to ensure safety and smooth traffic flow.

Stopping on merging and demerging lanes is forbidden as it can obstruct vehicles trying to enter or leave the roadway, creating potential hazards. Similarly, stopping on lanes marked with direction arrows is also prohibited because it can confuse other drivers and disrupt the intended traffic flow.

It's essential to recognize that certain locations are designated as no-stop zones to maintain road safety for all users. The omission of the third option, stopping in front of entrances to and exits from property lots, is relevant as well; stopping there can hinder access for vehicles entering or exiting the property, causing additional congestion and potential accidents. Understanding and adhering to these regulations is crucial for safe driving.
