Which car will be the last to drive through the intersection:

Explanation

The red car.

The yellow diamond beside the road means "priority road", and the white supplementary plate beneath it shows that the priority road does not continue straight but turns at the junction. According to the map on that plate, the priority road runs from the right-hand branch into the branch from which the green car is coming. That is, the green car and the blue car are on the priority road, and the red car, coming from the left-hand branch, is on the minor road.

That single sentence produces the answer: a driver on the minor road must give way to all vehicles on the priority road, regardless of which way they are turning. So the red car is the last to pass. Between the two priority-road cars the right-hand rule settles matters: the blue car is on the green car's right, so blue goes first and green after it.

The trap in this question is the green car's indicator. Green has signalled left and is leaving the priority road; the candidate's mind thinks "since it is leaving the priority road, it loses its priority". No such rule exists. Priority is determined by the road you are on now, not the road you are heading for. Practical rule: wherever you see a priority-road sign together with a direction plate, first establish which branch the priority road runs from and to; the rest of the decisions then fall into place by themselves.

• The blue car is on the priority road and is moreover on the green car's right; by both criteria it is the first to pass, not the last. • The green car is also on the priority road and need only give way to the blue car on its right, so its place is second; leaving the priority road does not destroy priority.
