What are the effects of driving at high speed in motor vehicles with combustion engines?

Driving at high speed in vehicles with combustion engines leads to increased fuel consumption and greater emissions of harmful substances. These effects are significant as they contribute to environmental pollution and can negatively impact air quality, which is a concern emphasized in German traffic regulations.

In Germany, regulations aim to minimize both fuel consumption and harmful emissions, promoting safer and more eco-friendly driving behaviors. Therefore, recognizing the impact of speed on these factors is crucial for responsible driving and adherence to traffic laws.

The statement about noise level being reduced is incorrect as high speeds typically result in higher noise levels, which is detrimental to community well-being and also addressed in German traffic provisions. Understanding the full implications of speed on fuel, emissions, and noise helps promote safer driving practices.
