As you approach an intersection scan around and through the intersection for traffic controls and other road users already in the intersection.

Explanation:

When approaching an intersection you need to get a good visual overview of what is going on from all directions.

If you are approaching an intersection with traffic lights you should be scanning well ahead, therefore you should be prepared to stop if you see that the lights are green from a distance because they will most likely be red by the time you get to the intersection.

At any rate, be prepared to yield to the traffic ahead of you or that are already in the intersection.
