¿Cuál es la velocidad máxima permitida a un turismo con remolque de más de 750 kg circulando por una autovía?

Maximum speeds for motor vehicles with a trailer (whatever its maximum authorised mass): motorways (autopistas) and dual carriageways (autovías), 90 km/h; conventional roads, 80 km/h; unpaved roads, 30 km/h. On urban roads, depending on the type of carriageway: a) 20 km/h on single-level streets where the carriageway and pavement are at the same level; b) 30 km/h on roads with only one lane in each direction; c) 50 km/h on roads with two or more lanes in each direction (40 km/h for vehicles carrying dangerous goods). Lanes reserved for certain users or only for public transport are not counted for this purpose. The local authority may lower or raise these limits with specific signs. On travesías the limit is 50 km/h for all vehicles, except vehicles carrying dangerous goods, which have a limit of 40 km/h. The local authority may lower this limit by agreement with the road owner, with specific signs.
