Why it matters: Maximum speeds per road type: the five-rung ladder

The ladder is not an abstract distinction. On the Lindelaan in Wijk bij Duurstede, children play at street level — 50 km/u there is already dangerous, let alone 80. On the N225 outside Bunnik, other traffic does not expect you to suddenly drive 100 as if on an autoweg. Whoever mixes up the five rungs drives too fast or too slow at the wrong moment — both are exam errors and both are dangerous.
