What it means
The Spanish DGT sign R-104 belongs to the regulatory signs family (circular (red or blue)). It means: no entry a motocicletas. 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.
