Since 2016 France has been conducting a trial in certain cities with allowing motorised two-wheelers and three-wheelers to pass between two lanes of cars.
The trial, which happened in the greater Paris Île-de-France region plus the départements containing Marseille, Bordeaux and Lyon, ended on January 31st 2021, with its results described as 'disappointing'.
The trial was authorised on roads within the test areas that had at least two lanes and a central barrier and where the maximum speed was equal to or greater than 70km/h.
Contrary to what the French road safety authority had hoped, accidents increased by 12 percent on the roads where the trial was taking place.
The temporary exemption has therefore ended and the practice is now illegal across France – although quite likely to still be widely practised.
