Traffic Rules and Right-of-Way
Right-of-way questions test a small set of rules applied consistently. At an unmarked intersection the default is to yield to traffic approaching from the right. At a roundabout, traffic already circulating has priority unless signs or markings say otherwise. When turning, you yield to oncoming traffic when turning across it and to pedestrians and cyclists continuing straight. A vehicle leaving a private driveway, car park or unpaved track yields to all traffic on the public road.
Beyond priority, know the core conduct rules: drive on the right, keep a safe following distance, overtake on the left and only where visibility and markings allow, and never overtake at a pedestrian crossing, on a blind crest or at a junction. Emergency vehicles with sirens and flashing lights have priority; you must facilitate their passage, usually by pulling to the right and slowing.
Traps: questions often add a sign that changes the default rule, so always check whether a stop sign, yield sign or priority-road sign is present. Another trap is the 'equal priority' scenario where two vehicles arrive together; the vehicle on the right goes first. Do not assume a larger vehicle automatically has priority.
Rule of thumb: check for signs first, then apply the default (yield to the right). Worked example: you arrive at an unmarked crossroads at the same moment as a car from your right; that car proceeds first, and you proceed only when it is safe.
