The sign you are referring to is the "Special Vehicles and Transport Goods Free" sign (1026-60). This sign indicates that the regulations for special vehicles and the transport of goods are exempt from specific restrictions, usually seen in areas like low-emission zones or streets with limited access.

In practice, this means that certain vehicles, typically those that are classified as special vehicles (such as emergency vehicles, waste collection trucks, or vehicles for people with disabilities) can enter or use these areas even if other vehicles are restricted.

It's important for drivers to be aware of this sign because it clarifies that while there are restrictions in place for most vehicles, special circumstances apply to certain vehicles that facilitate essential services or functions.

If you have any further questions about driving rules or another sign, feel free to ask!
