The traffic sign you mentioned, known as "Special Vehicles and Transport Goods Free" (Verbal indication 1026-63), indicates that the road is designated for the exclusive use of special vehicles and for the transport of goods. This means that regular vehicles are prohibited from using this route.

Typically, this sign is used in areas where certain types of vehicles, like buses, delivery trucks, or emergency vehicles, are permitted to operate, while other vehicles must find alternate routes.

It is important for drivers to pay close attention to this sign to avoid potential fines and ensure road safety by not obstructing designated routes for special vehicles. If you have any more questions about traffic rules or need clarification on another sign, feel free to ask!
