A new report has identified some of Spain’s dangerous roads 2026 drivers may want to watch more closely, with several stretches showing accident risk far above the national average. The findings suggest that, despite years of road safety campaigns, black spots remain a serious issue on parts of Spain’s state road network.
The study was published by Automovilistas Europeos Asociados (AEA), which analysed accident concentration stretches on Spain’s state roads over the five years from 2020 to 2024. According to the report, the average danger index across the state road network has remained at 8.2, unchanged from the previous five-year period.
Where the risk is highest
On conventional roads, the report says the most dangerous stretches were found on the N-632 in Asturias, specifically at kilometres 55 and 59 on the route linking Villaviciosa and Gijón. AEA says the danger index there is more than 167 times the national average, making it the worst-performing conventional road section in the study.
When it comes to the highest number of crashes and victims, AEA points to the A-77a in Alicante, where the stretch at kilometre 0 recorded 93 accidents and 141 victims, the highest totals in the state road network covered by the report.
On toll motorways, the most dangerous stretch identified was on the AP-41 in Toledo, followed by sections of the M-12 in Madrid and the AP-7 in Alicante. The motorway ranking is based on AEA’s danger index rather than raw crash totals alone.
Why this matters for drivers in Spain
Spain has one of Europe’s most extensive road networks, and for many residents and visitors, driving remains the only practical way to move between smaller towns, inland areas and coastal destinations. That is why reports like this tend to resonate beyond the motoring world. They touch everyday commutes, long-distance journeys and holiday travel alike.
What stands out in this year’s findings is not just the existence of black spots, but the fact that the overall danger index has not improved compared with the previous five-year period. That suggests some long-standing problems remain unresolved.
AEA says its methodology focuses on one-kilometre stretches of state roads where the danger index is at least ten times higher than the national average. In other words, these are not roads singled out because of a single isolated crash, but stretches with a sustained concentration of accidents over time.
Not just a question of speed
Road safety debates in Spain often focus on speed limits, drink-driving and enforcement. But black spot data usually tells a more complex story. Visibility, design, merging layouts, traffic volume and road condition can all influence whether a stretch becomes accident-prone.
That matters because a road can feel routine to regular users and still carry a higher-than-average risk. For drivers heading into unfamiliar parts of the country, especially on longer spring and summer journeys, awareness of these routes can be useful.
What drivers should take from the report
The AEA study does not mean every journey on these roads is unsafe. Nor does it mean other roads are risk-free. What it does highlight is where accident concentration has been persistently high and where extra caution may be sensible.
If you drive regularly in Spain, especially across interprovincial routes, it is worth keeping an eye on updated road safety reports as well as live traffic alerts. A familiar road is not always a low-risk one, and the latest data shows some of Spain’s worst stretches are still causing concern in 2026.
