What applies on clearways for motor vehicles only?

On clearways for motor vehicles only, two important rules apply. First, no U-turns are allowed. This is to ensure smooth traffic flow and avoid sudden maneuvers that could cause accidents. Second, you must enter or join the clearway only at crossroads and junctions, which helps maintain organized and predictable traffic movement. The third option about driving faster than the visibility range of dipped headlights in darkness is not allowed, as German traffic law requires you to drive at a speed where you can stop safely within the visible distance. Following these rules helps keep traffic safe and efficient on clearways.
