On a conventional road (carretera convencional) outside a built-up area, what is the maximum speed the driver of a passenger car may reach while passing another vehicle?

Correct answer: 90 km/h.

90 km/h. When passing on a conventional road (carretera convencional), you must not exceed the general speed limit for your passenger car, which is 90 km/h, unless a sign sets a different limit. Passing no longer allows you to exceed the limit by 20 km/h.
