On a road near Simpelveld you see a broken line on the side of the carriageway, with no advisory lane, and no sign at all. Based on the marking alone: may you assume that 80 km/h is certainly allowed here?
No, the marking is an indication, not a guarantee — the real speed is on a sign
Yes, the '80 km/h' marking is just as binding as a sign
Explanation
Wrong — trap: marking treated as a binding rule. The marking IS an indication, but NOT a guarantee; the real maximum speed is shown by signs (Book p.79).
