How can you reduce the noise generated by your motor vehicle?

The combination you selected is correct because both strategies are effective in reducing noise generated by motor vehicles, which is important for maintaining compliance with environmental standards and local regulations regarding noise pollution.

Driving at a low engine speed minimizes the engine's operational noise, making it quieter on the road. Additionally, using tyres designed for low rolling noise can significantly decrease the sounds produced while driving. These practices contribute to a quieter urban environment, aligning with German traffic laws that prioritize noise reduction to protect residents' quality of life.

However, removing the air filter insert is not a viable option, as it can lead to increased noise and engine inefficiency, contrary to the goal of noise reduction and may violate vehicle maintenance standards. Proper vehicle maintenance, including the use of the correct air filter, is essential in German traffic regulations to ensure both vehicle performance and compliance with environmental standards.
