How can you avoid creating noise?

The answer you provided is correct since it includes strategies that can effectively reduce noise pollution in traffic situations. According to German traffic regulations, minimizing noise is important for environmental protection and the well-being of residents near roadways.

Option 1, which involves filling empty compressed air tanks from a stationary facility, helps to avoid unnecessary noise that might occur from engine operation elsewhere. Option 2, replacing worn-out side latches, is crucial because proper functioning of vehicle components prevents rattling noises that can be disruptive both to the driver and to others.

However, option 3, allowing the engine to idle during longer waiting times, contributes to unnecessary noise and should be avoided. Instead, turning off the engine when stopped for extended periods is more in line with noise reduction efforts.

Each option plays a significant role in adhering to German traffic laws aimed at promoting quieter, more environmentally friendly road usage.
