After years of trial and debate, the experimental authorisation of inter-lane circulation for two- and three-wheeled motorised vehicles in France is set to end on 31st December 2024. From 1st January 2025, motorcyclists will no longer be permitted to weave between vehicles during dense traffic, marking a return to standard road regulations under the Highway Code.
First introduced in 2016 in select areas and expanded in 2021 to 21 departments, including the Var and Alpes-Maritimes, inter-lane circulation (CIF) was allowed as part of a national effort to evaluate its potential to ease congestion and improve safety. However, despite years of experimentation, no conclusive data has emerged to justify its permanent integration into French road laws.
The announcement has sparked confusion and concern among motorbike advocacy groups, who argue that the practice has tangible benefits, including reduced travel times, lower emissions, and improved safety for riders when conducted within the established rules. Laurent, a member of the Fédération Française des Motards en Colère, told France 3, “Inter-lane circulation lets riders escape traffic safely. Most riders follow the rules, and the system works well.”
Mixed safety results and enforcement
Despite its perceived advantages, CIF has not been without challenges. In the Alpes-Maritimes, motorcyclists accounted for more than half of the 55 road fatalities in 2024. Authorities attribute these accidents to speeding, reckless behaviour, and substance use.
Starting in January 2025, motorcyclists caught practicing inter-lane circulation will face penalties, including a €135 fine and the loss of three points on their driving license. This enforcement marks a significant shift for riders accustomed to the trial’s flexibility.
A conclusive report on the trial is expected soon, but it may come too late to influence the decision.
