What do you have to particularly remember at crossroads and junctions in a built-up area?

In built-up areas, the "right before left" rule usually applies at intersections without priority signs. However, you must be aware that sometimes a narrow or less developed side street can have priority if it is a priority road, even if it looks less important. The appearance or condition of a road does not determine priority—only traffic signs and the law decide this. So, do not assume the broader or better-developed road has priority. This means answer 1 is correct because it reminds you not to judge priority by the width or condition of intersecting roads.
