The permissible maximum speed sign indicates the maximum legal speed limit that a vehicle is allowed to travel on that particular stretch of road. This sign is usually rectangular and features a white background with a red border. The specific speed limit is shown in black numbers, with kilometers per hour (km/h) indicated.

In Germany, adhering to speed limits is very important, as exceeding these limits can lead to fines and penalty points on your driving record. It's essential to pay attention not only to these signs but also to other factors such as road conditions, weather, and traffic regulations, which may require you to adjust your speed accordingly. Always remember that speed limits can vary in urban versus rural areas, and different limits may apply in different traffic conditions.
