All roads in Spain have a maximum permitted speed limit. However, that limit not only varies depending on the characteristics of the road, but also the type of vehicle.
As always when we talk about this subject we must offer the same reminder however, the maximum permitted is exactly that, a maximum, it is not a target and the actual safe speed may be much lower depending on the road and weather conditions.
That said, here is the overview of the generic maximum permitted speed on the roads by vehicle type, unless signs say otherwise.
PASSENGER CARS AND MOTORCYCLES
The maximum generic speed for cars and motorcycles on motorways and highways is 120 kilometres per hour. On secondary roads, the maximum permitted speed is either 100 kilometres per hour or 90 kilometres per hour depending on the width of the hard shoulder. In towns and cities the maximum permitted speed is 50 kilometres per hour.
BUSES
Buses, and other vehicle derivatives that have been adapted, must not exceed 100 kilometres per hour on motorways and highways. On conventional roads, the maximum permitted speed is reduced to 90 kilometres per hour, as long as it has a paved shoulder of 1.5 metres or more in width or more than one lane for traffic in any direction. On other conventional roads out of town they cannot exceed 80 kilometres per hour. In the event of a bus carrying standing passengers (where permitted) the maximum permitted speed, whatever the type of interurban road, is 80 kilometres per hour.
TRUCKS
On motorways and highways, trucks, articulated vehicles, tractors and vans cannot exceed 90 kilometres per hour. On conventional roads outside of towns, the maximum permitted speed is 80 kilometres per hour and 70 kilometres per hour, depending on the width of the hard shoulder.
SPECIAL TRANSPORT
Any vehicle which falls into this category, namely a bus carrying school children and displaying the yellow school bus sign, or a vehicle carrying goods classed as dangerous, the maximum permitted speed must be reduced by 10 kilometres per hour.
TOWING A TRAILER
The maximum permitted limit on motorways and highways is 90 kilometres per hour when towing a light trailer (which has a maximum mass less than or equal to 750 kg) and 80 kilometres per hour when towing a non-light trailer (greater than 750 kg). On conventional roads with a hard shoulder of 1.5 metres or more the maximum permitted speed is then 80 kilometres per hour, and on other interurban roads the limit is 70 kilometres per hour.
QUADS, TRICYCLES AND BICYCLES
Vehicles with three wheels or “quads” have their speed limited to 70 kilometres per hour on any type of road where they are permitted to drive.
Cycles, two and three wheeled mopeds and light quadricycles have a maximum speed of 45 kilometres per hour where permitted.
