Afficher la réponse et l'explication
Bonne réponse : B. Orange warns of temporary conditions (work zones); yellow warns of permanent road conditions

Colour signals the permanence of the hazard. Yellow diamonds = permanent hazard conditions (curves, slippery spots, animal crossings). Orange diamonds = temporary (construction, detours, work zones). The shape is the same — both diamond — but colour tells you whether to expect change after the area.
