In the absence of signage, what is the maximum permitted speed for a van when driving on a high-capacity divided highway (autovía) that runs within a built-up area?

Correct answer: 80 km/h.

Without signs, no vehicle may exceed 80 km/h on a high-capacity divided highway (autovía) through a built-up area, including a van. Outside the built-up area, the van could travel at 90 on that highway.
