. With the treat of coming to you to analyze your car's fumes, the French government wants motorists to maintain their vehicles properly and, eventually, will ban the most polluting ones.
Last year, more than 1,700 controls were made, which uncovered 360 contraventions in Paris alone.

Similar controls exist in Spain, where noise pollution is also taken into consideration.
