At a junction in Schoonhoven you have a green light and priority over the crossing traffic. Right after the junction traffic is completely gridlocked, no room to drive through. What do you do?
I drive on, because I have a green light and priority
I drive on, the blocking prohibition only applies at a red light
I wait before the junction until there is room to drive through again
Explanation
Wrong — trap: confusing priority with a clear path. The blocking prohibition is independent of priority: if the far side is at a standstill, you wait before it (Book p.103).
