According to the Risk Map report by RACC, this section in Tarragona has a risk index of 200.9, far exceeding other dangerous roads in the country. The study, based on iRAP methodology, analyzed data from the 2022-2024 period.

The N-420 road, also passing through Tarragona, ranks second in the country for the total number of high-risk kilometers. In Catalonia, the overall risk average stands at 11%, although Girona remains a concern with 18% of its state-managed roads classified as dangerous.

For the first time in 15 years, the RACC noted an increase in risk levels on high-capacity motorways. However, conventional single-carriageway roads remain the most hazardous, with an accident probability four times higher than on highways.
