About Maximum speeds per road type: the five-rung ladder: which statement is WRONG?
The text itself explicitly says 'unless signs indicate a different maximum'.
The woonerf has its own, lower maximum of 15 km/u; the 30 km-zone a separate maximum of 30 km/u.
Km/u applies on ORDINARY roads outside the built-up area.
The standard maximum speed on the autosnelweg is 100 km/u.
Explanation
trap: daytime-figure-as-standard. Book p.119 (see maxima.daglimiet_100) - the LEGAL standard speed on motorways is 130 km/u; 100 is the daytime reduction between 06:00 and 19:00. This atom only covers the non-motorway ladder; the day/night nuance lives in the sister atom
