True or False: Racing engines are allowed on public roads in Germany.

In Germany, racing engines are not permitted on public roads. This regulation stems from the country's commitment to road safety and standards regarding vehicle emissions and noise. Racing engines typically produce higher levels of noise and emissions compared to standard engines, which can contribute to environmental pollution and public disturbance in urban areas.

Additionally, vehicles equipped with racing engines often lack the necessary safety features and modifications that make a car appropriate for public road use, such as crash safety standards and sometimes insurance and registration requirements. Therefore, operating such vehicles on public roads is generally prohibited to ensure the safety of all motorists and pedestrians.

The other options, such as allowing racing engines under certain conditions or events, do not align with the strict regulations enforced in Germany regarding vehicle modifications and road safety. Hence, the assertion that racing engines are allowed on public roads is false.
