These are the most dangerous roads in Spain

roads will be busy over Easter

The holiday in Spain is coming. And that means that it will be busy again on the Spanish roads. Research by RACE, the Spanish equivalent of the ANWB, shows that almost 2,000 kilometres of roads in Spain are labelled ‘dangerous’.

Specifically, it is 1,974 km, which represents almost 8% of the 25,100 km analysed. The results are contained in the report ‘Assessment of the state of the national road network (RCE) for the period 2020-2022’.

Between 2020-2022, a total of 2,987 accidents occurred on the national road network. Of these, 982 were fatal accidents, with 1,096 deaths and 2,616 serious injuries. According to the data from the study, 56 high-risk routes have been located. That’s 8 more than in the previous report. Of the 56 routes, nine are ‘black’ sections. These have a high risk to the safety of users. In addition, there are 47 sections that are considered ‘red’, that is, they are of medium risk.

Positive development

The evolution of the number of fatal and serious accidents on the Spanish national road network is very positive. It shows a decrease of more than 73% compared to 2009, the beginning of the study, and 50% compared to the data of the last decade (2013 -2023). Since 2019, there has been a continuous decline.

This region has the riskiest roads

Catalonia is the autonomous community with the highest percentage of roads considered high-risk, with 11.3% of roads, followed by Castilla y León with 9.9%. However, the section of the N-345 in the Region of Murcia (between kilometers 0 and 7.2) is the most worrying of all, as it has a high-risk index from the report from 2017 to 2019. Also of concern are the sections of the N-323 in Granada (between kilometers 172.5 and 190.3) and the N-634 in Cantabria (between kilometers 232.8 and 243.1) which are among the most dangerous since the 2019 and 2021 studies.

What are the most dangerous routes on Spanish roads?

RACE’s analysis explains the profile of the most dangerous roads. First of all, a conventional road, with a lane, intersections at the same level and an average vehicle intensity of less than 10,000 vehicles per day. The safest roads, paradoxically, are those on which most vehicles travel.

The study shows that the N-6 in Galicia, between kilometre points 517.1 and 528.5, is the road with the highest risk of a serious accident. The rest of the very dangerous black sections are located on the N-323 (Andalusia), N-631 (Castilla y León), N-345 (Murcia), N-432 (Andalucia), N-502 (Castilla y León), N-634 (Cantabria), N-340 (Valencian Community) in N-642 (Galicia).
