You are parked on the right in a residential area near Alkmaar and want to pull away. You have checked the interior mirror and the left door mirror and see nothing. May you now signal and pull away immediately?
Yes, checking two mirrors is enough
No — first look beside you to the left (blind spot), only then signal
Explanation
Wrong — trap: blind spot skipped. After the mirrors you look beside you to the left last; that glance covers what no mirror shows (Book p.134).
