About Special markings: yellow lines, bus strips, block markings, filter lanes: which statement is correct?

Along a yellow line you may always stop briefly, as long as you are not parking — regardless of whether the line is solid or broken.

A bus strip marked 'BUS' may only be used by scheduled buses.

Drivers are REQUIRED to follow, at a junction, the direction their filter lane indicates.

Block markings (staggered white blocks) forbid overtaking, just like a solid line.
