About Motorway: 130 standard, 100 by day — and the fixed 80 on some ring roads: which statement is WRONG?
130 km/u is the exception, meant only for quiet night-time hours; 100 km/u is the real standard figure.
The standard is 130 km/u; 100 km/u only applies between 06:00 and 19:00.
The exact time window is 06:00 to 19:00, not 07:00-20:00.
The ring-road exception of 80 km/u is a PERMANENT, location-bound maximum, independent of the clock; it does not change between day and night.
Explanation
trap: inverted standard. Book p.119 - the text explicitly calls 130 km/u 'the standard maximum speed'; 100 km/u is the speed 'reduced' between 06:00 and 19:00
