You are driving a motor vehicle with a manual gearbox. When driving, what can cause avoidable noise pollution?

Your selected combination is correct because all three factors contribute to avoidable noise pollution. Heavily accelerating unnecessarily creates excess noise from the engine. A defective silencer can significantly increase the sound emitted from the exhaust, making the vehicle much louder. Additionally, driving fast in low gears, commonly referred to as revving the engine, generates more noise than necessary.

According to German traffic regulations, it is important to minimize noise pollution for the sake of public peace and environmental protection. Therefore, being mindful of these actions not only complies with the law but also contributes to a quieter and more pleasant community.
