Is the circulation of vehicles and mopeds with so-called open exhaust permitted?

# Open Exhaust in Vehicles Open exhaust is **totally prohibited** in any type of vehicle, including motorcycles and mopeds. This regulation exists because exhausts without a silencer generate excessive noise pollution, affecting the well-being of other road users. Every vehicle must drive with its original exhaust system or a homologated one that meets the noise limits established by law.
