In February 2022, the speed limit on the boulevard périphérique, a major ring road around Paris, was reduced from 70 km/h to 50 km/h to improve road safety and reduce pollution. This decision was met with strong opposition from local associations and drivers, who argued that the lower limit would cause traffic congestion and increase the risk of accidents. As a result, they took legal action to challenge the change. Two years later, the issue is still before the courts. The appeal brought by these groups is currently being reviewed by judges, who are considering whether the original speed limit should be reinstated. The case has drawn attention due to the balance between public safety concerns and the practical challenges of reduced speed limits in urban areas. The State, represented by the government, continues to oppose the return to the 70 km/h limit. Officials argue that the reduction has had a positive impact on reducing emissions and improving road safety, particularly for pedestrians and cyclists in the surrounding neighborhoods. They emphasize that the decision was based on thorough studies and public consultations. The outcome of this legal review could set a precedent for similar speed limit changes in other cities across France. While the debate continues, the focus remains on finding a balance between environmental goals and the daily needs of drivers and residents.
