Vehicles will drive through the intersection in the following order:

Explanation

The lorry, then the passenger car, then the bus and last the tanker.

The yellow diamond "priority road" together with the supplementary plate shows that the thick line comes from the road on the right and turns into the road the white car is on. So the priority road enters the junction from the right and continues towards the white car; the lorry on the right and the white car are both on the priority road, and the yellow minibus on the left and the tanker opposite are on the minor road.

Because the priority road changes direction within the junction, these two drivers apply the right-hand rule between themselves: the lorry is on the white car's right, so the lorry first and then the car. Then it is the minor road's turn and the same rule repeats: the minibus is on the tanker's right, so the minibus first and the tanker last.

The reliable way to solve this type of question is two-stage: first divide all the vehicles into the "priority road" and "minor road" groups, then apply only the right-hand rule within each group. Never mix the groups. The exam trap is that the tanker is large and heavy and the mind pushes it forward; but the weight and dimensions of a vehicle play no part in priority.

• This puts the bus ahead of the passenger car; the bus is on the minor road and the white car on the priority road, so it never goes ahead of it.
