Core: The precedence order: who wins when signs disagree?

The legal basis is built from separate, literal law articles: the law requires following instructions from authorised officials AND traffic controllers, with no limitation to accidents. The law states it directly: instructions outrank traffic signs and traffic rules — the highest rung. The law governs the second rung: traffic lights outrank traffic signs that regulate priority, such as priority signs and shark's-teeth markings. A traffic sign therefore never beats a working light. The law governs the third rung: traffic signs outrank traffic rules, insofar as those rules are incompatible with the signs — a sign beats the priority-to-the-right rule, not the other way round. A road marking (solid line, shark's teeth) is legally itself a traffic sign, not a separate category — it sits on the same rung as a signpost.
