About Autoweg and autosnelweg: G3, G1 and the speed rules: which statement is WRONG?
Using the hard shoulder, refuge bay or verge with the car is forbidden, except in an emergency (for example a breakdown).
During the day (6.00-19.00) the maximum speed is 100 km/u; in the evening and at night it is 100, 120 or 130 km/u. 130 is not the default, it is the highest of three possible evening/night values.
'able and permitted to drive 50/60 km/u' is an access requirement for the vehicle (a floor), not a speed limit. The maximum speed on motorways is stated separately: 100 km/u during the day, 100/120/130 in the evening and at night.
Autoweg (expressway) and autosnelweg (motorway) are the same kind of road, with the same minimum speed and hard shoulder.
Explanation
trap: signs confused. Book p.70-71 - an autoweg (G3) requires min. 50 km/u and may have at-grade junctions; an autosnelweg (G1) requires min. 60 km/u, always has separated carriageways with a hard shoulder, and never at-grade junctions
