The sign "other vehicle-person groups free" (sign 1028-33) indicates an area where certain types of vehicles or groups of people are allowed to enter or use the road, while others may not. This sign is often used to specify that certain restrictions do not apply to specific vehicles, such as bicycles, public transport, or other types of non-motor vehicles. It can also indicate that areas are open to pedestrians or specific groups that are otherwise restricted.

In practice, this means that if you see this sign, certain vehicle and pedestrian access restrictions may not apply, allowing those indicated groups to use that part of the road. It is essential to pay attention to any additional information provided on the sign or nearby signage, which could specify exactly which groups are allowed.

Understanding these nuances is crucial for safe and legal driving in Germany, so always be observant of the signs and their implications for your intended route. If you have more specific questions about driving rules or another sign, feel free to ask!
