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

At crossroads and junctions in built-up areas, it's crucial to understand that intersections can vary significantly. The correct answer emphasizes that even narrower and less developed roads can have priority over more prominent roads. This is important because it reflects the German traffic regulation that indicates priority rules are not solely determined by the apparent development or size of the road.

Priority at intersections is determined by specific traffic signs, regulations, and local rules rather than just the physical characteristics of the roads. The idea that "right before left" applies generally is true but can be superseded by signs indicating priority. Therefore, when approaching a junction, pay attention to signs to determine which road has the right of way, rather than making assumptions based on the road's development. Understanding this helps ensure safe navigation through intersections and compliance with traffic laws.
