Traffic Rules and Right-of-Way
The hierarchy of priority
Right-of-way questions are decided by a strict order. First, signals (police officer, then traffic lights, then signs) override everything else. Second, signs and markings decide between conflicting flows. Only when neither signals nor signs settle the matter does the general rule apply: at an unmarked intersection of equal roads, yield to traffic approaching from the right.
Turning, junctions and crossings
When turning left you cross oncoming traffic, so you yield to vehicles coming straight or turning right. When turning right you must give way to pedestrians crossing the road you are entering and to cyclists continuing straight. At roundabouts, traffic already circulating has priority unless signs say otherwise; signal right on exit. Reversing, leaving a parking place, or changing lanes never confers priority - you must not obstruct others.
Distance, speed and following
Keep a gap of at least the distance covered in two seconds in good conditions, more in rain or on gravel. Speed limits in built-up areas, outside them, and on motorways differ, and local signs may lower them; questions often test the limit for the category of road or vehicle, not the general figure. Adjust speed so you can stop within the distance you can see to be clear.
Traps
Distractors exploit the difference between having priority and being safe: priority must still be given up to avoid a collision. Another trap is a T-junction where the through road has priority by sign, so the right-hand rule does not apply. Watch also for trams, which generally have priority over other vehicles at equal junctions.
Rule of thumb
Resolve every priority conflict in this order: officer → lights → signs → right-hand rule. If two answers both seem right, the one that yields is usually correct.
