On a road outside of town with more than one lane in either direction, what is the speed limit?

Why this is the correct answer

In Spain, roads outside built-up areas (fuera de poblado) are divided into two types: motorways/dual carriageways (autopistas/autovías), where the speed limit is 120 km/h for cars, and conventional roads (carreteras convencionales), where the general speed limit is 90 km/h for cars and motorcycles. The question asks about a "road outside of town" — meaning a conventional road, NOT a motorway. On conventional roads, the speed limit is always 90 km/h by default, no matter how many lanes the road has in each direction. The number of lanes does NOT change the speed limit. This is different from urban roads (inside towns), where the number of lanes DOES determine the speed limit (20, 30, or 50 km/h). So why does it matter that it says "outside of town"? Because Spanish law sets different speed rules for roads inside towns (en poblado) versus outside towns (fuera de poblado). Outside towns, on conventional roads, the default is always 90 km/h for cars. The only exception: if a conventional road has a physical barrier separating the two directions of traffic AND the road authority has posted specific signs allowing it, the limit can be raised to 100 km/h — but this must be explicitly signposted and is never the default. Without such signs, 90 km/h applies uniformly to the entire road (both directions). Do not confuse conventional roads with motorways, where the limit is 120 km/h.
