At a junction in Dordrecht you want to turn left. The oncoming driver does not indicate and drives straight ahead. You think: 'right-turn-before-left-turn, so that rule decides who goes first here.' Is that correct?
No — that driver is not turning, so the ordinary turning rule applies: I give way to the straight-ahead traffic
Yes — 'right-turn before left-turn' applies to every oncoming driver, turning or not
Explanation
False — trap: rule-applied-to-wrong-situation. 'Right-turn before left-turn' only applies if the oncoming driver is also turning; here the ordinary turning rule applies (Book p.110-111).
