Traffic Rules and Right-of-Way

This domain tests who moves first and which lane or position is lawful. Questions usually describe two or three vehicles arriving at an intersection, a roundabout or a pedestrian crossing, and ask you to identify the order of movement.

General rules

Keep to the correct side of the road and use the rightmost lane unless overtaking. Signal before every manoeuvre and cancel afterwards. Do not enter a junction unless your exit is clear, even on green. Maintain a safe gap and obey lane arrows.

Priority at intersections

At an uncontrolled intersection, many European systems apply priority to the right; a yield or stop sign changes that rule. At a roundabout, yield to traffic already circulating unless signs say otherwise. A driver turning left across oncoming traffic must yield to that traffic. Pedestrians on a marked crossing have priority; when turning into a side road, yield to pedestrians crossing that road.

Worked example

Car A travels straight on a main road. Car B emerges from a side road controlled by a yield sign. B must yield to A even if A is signalling to turn right into B’s road, because the yield sign requires B to give way to traffic on the main road. Reasoning: the sign controls priority, not the width of the road or the size of the vehicle.

Traps that cost marks

Assuming the wider or busier road always has priority; forgetting to signal your exit at a roundabout; yielding to a vehicle that actually faces a stop sign; blocking a box junction while waiting to turn.

Key points

  • At uncontrolled intersections, apply priority to the right unless a sign says otherwise.
  • At roundabouts, yield to traffic already circulating.
  • A left-turning driver yields to oncoming traffic.
  • Pedestrians on a marked crossing have priority.
  • Never enter a junction unless your exit is clear.
