¿Cuál será el límite de velocidad circulando por una travesía?

The general speed limits on urban roads, depending on the features of the carriageway, are: 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 a single 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). For this purpose, lanes reserved for certain users or only for public transport are not counted. The municipal authority may lower or raise these limits with specific signs. On travesías a limit of 50 km/h applies to all types of vehicle, except vehicles carrying dangerous goods, for which it is 40 km/h. This limit may be lowered by agreement between the municipal authority and the road owner, with specific signs.
