Ban on avoidable exhaust noise
The core of the new regulation is the explicit ban on avoidable exhaust noise, in particular the deliberate generation of banging noises, also known as “pop and bang”. This mainly affects vehicles that deliberately cause misfiring and loud noises through special settings such as sport modes or the use of quickshifters or the kill switch, for example. One of the aims is to severely restrict the tuning scene, which is said to be known for such practices.
Drivers and motorcyclists who violate this regulation risk fines of up to 10,000 Swiss francs (approx. 10,200 euros, 11,000 USD). According to the Federal Roads Office (FEDRO), such cases can be easily detected and punished by the police. The exact amount of the fine depends on the individual case and is determined by the courts.
Higher penalties for leaving the engine running unnecessarily
Unnecessary engine running will also be punished more severely from 2025. The fine will increase from 60 to 80 francs. This regulation applies to both cars and motorcycles that leave the engine running for no reason when stationary, thereby generating avoidable noise. It should be noted that warming up the engine does not count as a reason and is not permitted.
Procedure for foreign vehicles
Special regulations apply to drivers from abroad who are stopped in Switzerland for noise offenses. Anyone caught driving a foreign vehicle must usually pay the fine immediately on the spot. If this is not possible, the vehicle can be impounded until the fine is paid. The Swiss authorities can also make a report to the competent authorities in the driver’s country of origin in order to prevent repeat offenses.
Use of noise speed cameras planned
In the medium term, the Federal Council is considering the use of so-called noise speed cameras. These devices are designed to automatically detect and register noisy vehicles. A corresponding pilot project in the canton of Geneva was successful. However, legal and technical issues still need to be clarified before noise cameras can be introduced nationwide.
Conclusion: Strict measures to reduce noise
With the new regulations from 2025, Switzerland is pursuing a consistent strategy to reduce noise in road traffic. Drivers and motorcyclists who generate avoidable noise will face severe penalties. The focus is particularly on deliberately generated exhaust bangs and unnecessary engine operation. The new regulations apply equally to domestic and foreign drivers and are intended to help improve the quality of life in heavily polluted areas.
(Art. 42 para. 1 SVG)
Drivers, passengers and assistants must not generate any avoidable noise. In particular, the following are prohibited
- a) unnecessary preheating and running of the engine of stationary vehicles;
- b) high engine speeds when idling or driving in low gears;
- accelerating the vehicle too quickly, especially when starting off;
- continued unnecessary driving in built-up areas;
- Causing avoidable noise from the exhaust system, in particular making banging noises by changing gear or abruptly opening the throttle;
- Careless loading and unloading of vehicles;
- Slamming car doors, hoods, boot lids and the like;
- Interference caused by sound reproduction devices installed or carried in the vehicle.
