What it means
The Spanish DGT sign P-31 belongs to the warning signs family (triangular, red border). It means: congestion. 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.
