You are riding a moped with a maximum design speed of 25 km/h. How do you need to protect yourself from head injuries?

As a rider of a moped with a maximum speed of 25 km/h in Germany, you are required to protect your head with a suitable and well-fitting motorcycle helmet. This is in accordance with the German Road Traffic Act (StVO), which mandates that riders of two-wheeled vehicles, which can include mopeds, wear helmets to reduce the risk of head injuries in case of accidents.

While a bicycle helmet might seem like an option, it is not designed to provide the same level of protection as a motorcycle helmet in the event of a fall or collision at higher speeds. Additionally, even if traveling at walking speed, wearing a proper helmet is a precaution that can prevent injuries in unexpected situations, reinforcing the importance of helmet use at all times when riding.

Therefore, the correct answer emphasizes the necessity of wearing a motorcycle helmet for maximum safety while riding a moped, regardless of your speed.
