Which vehicles are not allowed to drive here?

The sign shown indicates that motorized bicycles are prohibited from entering this area. According to German traffic regulations, certain road signs restrict specific types of vehicles to ensure safety and proper traffic flow.

In this case, "motorized bicycles" refer to vehicles that are powered by a motor but fall below a certain power threshold, making them different from small motorcycles and light motorcycles, which may have different regulations.

This restriction helps maintain a safe environment, particularly in areas where larger vehicles or certain traffic conditions may not be compatible with smaller, less powerful vehicles. Understanding these regulations is crucial for adhering to traffic laws and ensuring safety on the roads.
