What applies on clearways for motor vehicles only?

Your selection of options 1 and 2 is correct as they both reflect important regulations regarding clearways for motor vehicles in Germany.

1. No U-turns: This rule is designed to maintain the flow of traffic in clearways, as U-turns can create hazards and disruptions.

2. Join the clearway only at crossroads and junctions: This rule ensures that drivers enter and leave clearways safely, reducing the risk of accidents in high-traffic areas.

The option you missed, which is option 3, states that in darkness, you may drive faster than the range of visibility allowed by dipped headlights. This is incorrect because it poses a significant safety risk; driving outside the visible range of your headlights can lead to dangerous situations, such as not seeing obstacles or pedestrians.

Understanding and adhering to these regulations is crucial for maintaining safety and traffic flow on clearways. Educating yourself about all relevant options helps ensure responsible driving behavior.
