Radar systems have been in operation on the city highway in Strasbourg and on expressways in five other French cities since 2023, with fines also being imposed on vehicles that adhere to the speed limit.
This is because a very special rule applies in certain lanes. Drivers who are alone in the car and illegally use the left-hand lane, which is reserved for car pools or cars with at least two occupants during rush hour, are flashed. The lane is also open to electric cars with a green French environmental badge, regardless of the number of occupants.
A new traffic sign - a white diamond on a blue background - indicates the regulation. Anyone who ignores the sign must expect a fine of 135 euros. Tourists are also affected by the regulation.
Speed cameras record the number of people
As the Paris Ministry of the Environment recently announced, the regulation, which has so far been sporadically checked by the police, is so often disregarded that the hoped-for success of the separate lanes - namely getting to your destination faster as a carpool in rush hour traffic - is jeopardized.
The speed cameras can detect whether one or more people are in the car. The ministry hopes that the separate lanes will above all reduce pollutant emissions.
According to Laura Martin, spokesperson for the city of Strasbourg, the aim is to reduce the number of commuters traveling alone in their cars to the Alsace metropolis.
