Spain's most dangerous roads are in Andalucía, Galicia, Asturias and Castilla y León

Although none of these is in the region of Asturias, the research by the RACE claims this is the second-most likely place in Spain where car crashes are likely to happen, after Galicia.

They studied 1,350 stretches of road over a distance of 23,340 kilometres where 7,002 fatal motor accidents had occurred in the three-year period between 2009 and 2011.

The top two most dangerous roads were in Galicia – the SC-21 in the province of A Coruña leading from the airport of Santiago de Compostela, the city which houses the famous pilgrim's cathedral, and the N-640 in the province of Lugo, between Pontevedra and Meira.

In third place was the N-632 in the Gijón area of Asturias, between Piles and Venta de las Ranas.

The rest of the top 10 included, in descending order, the N-225 in the Grao area of Castellón in fourth place; the A-7 in Castel de Ferro (Granada province); the N-234 in Navaleno (Soria province); the N-125 leading from Zaragoza airport; the N-640 in San Tirso (Lugo province); the N-610 in Castromocho (Palencia province), and the N-122 in Valdelavillo (Soria province).

By regions, after Galicia and Asturias, those with the highest numbers of accident blackspots are Castilla y León, Extremadura, Andalucía, Aragón and Castilla-La Mancha.

The most dangerous province for motorists is León, which has one kilometre of high-risk road in every 10, followed by Sevilla, Huelva and Ourense (Galicia).

For motorcyclists and moped-riders, the Manises-Valencia road, the N-125 near Zaragoza airport, the A-7 near Algeciras (Cádiz) and the roads in and around A Coruña, Sevilla, Granada and Málaga claimed the most lives in the last three years.
