You leave Wijk bij Duurstede via a 30 km-zone near a primary school, then exit the built-up area onto the N225, and further on you see a blue sign with a car silhouette. What speed applies on that last stretch?
100 km/u — the blue sign with the car silhouette marks an autoweg
80 km/u — outside the built-up area it's always 80 anyway
30 km/u — the 30-zone near the school stays in force until the next built-up area
Explanation
Wrong — trap: 80-everywhere reflex. The blue sign with the car silhouette marks an AUTOWEG: 100 applies there, not the ordinary 80 of an overige weg (Book p.117-118).
