Just before the junction you notice you are in the straight-ahead lane, while you need to turn left. A solid line separates the lanes. What do you do?
Go straight on and find another route to the left further on
Cross the line to the left lane, signalling
Turn left from my lane anyway, the arrow is only advice
Explanation
False — the arrow in your lane is not advice. It sets which direction you may take from that lane; you must follow it. (Theorie hoofdstuk 7 — Manoeuvres: wegrijden en voorsorteren)
