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

Your answer is correct. In German traffic rules, avoidable noise pollution from a manual vehicle can arise from three main causes: Heavily accelerating unnecessarily produces loud engine noise that can disturb others. A defective silencer (muffler) means the exhaust system cannot properly reduce engine noise, resulting in excessive noise. Driving fast in low gears causes the engine to rev at very high RPMs, which is noisy and avoidable by shifting to higher gears sooner. Understanding these helps minimize noise and is important for environmental and community consideration.
