What it means
The Spanish DGT sign S-450 belongs to the information signs family (rectangular or square, blue). It means: carretera autonomica of tercer nivel. As with every sign in this family, the theory exam typically combines it with right-of-way, speed-limit or general-traffic-rule questions — so it pays to memorise both the visual and the context in which it appears.
