About Pre-sorting: choosing the correct lane in time: which statement is WRONG?

You may quickly change lanes just before the junction.

The lane arrow mandatorily decides which direction you may take from that lane; you must follow it.

You must signal your intention to change lanes in time with your indicator.

You may never cross a solid line, even if there seems to be room.

Explanation

Pre-sorting must happen well in advance; switching too late or over a solid line is dangerous and not allowed.
