France’s 80 km/h speed limit cuts fatalities but not crash frequency
French authorities evaluated the 80 km/h speed limit applied to bidirectional roads without a central median in metropolitan France over an 18‑month period from July 2018 to December 2019, a timeline later disrupted by the pandemic.
The Cerema report shows the average speed on the targeted network fell by 3.3 km/h. While the total number of accidents did not decline, the severity of crashes improved: 331 fewer deaths were recorded over the 18‑month span (349 fewer when January‑February 2020 are included). On the remainder of the French road network, the death toll stayed roughly stable.
Supporters point to the lives saved, whereas critics argue the reduction reflects broader factors such as newer vehicles, better road quality, safety equipment, and driver behaviour. They also warn the limit may encourage dangerous overtaking, increase emissions, lengthen travel times and has low public acceptability.
