Core: Keeping right, road narrowing (F5/F6) and obstacles

The basics: you must keep right as much as possible, but not drive too close to the kerb or the verge. If the road is too narrow for you and an oncoming driver, you both move aside (Book p.60). At a road narrowing, signs F5-F6 usually decide who goes first: if you are driving toward the red arrow, you stop; if you are driving toward the white arrow, your oncoming driver stops. These signs apply only between drivers, not for example toward pedestrians (Book p.60). If there is no sign, the same basic logic without an arrow applies to an obstacle: when there is not enough room, whoever has the obstacle on their own half of the road must stop. If the obstacle is on the oncoming driver's half of the road, that driver stops — not you (Book p.61).
