Which sign communicates restrictions on freight carriage using an international symbol?

• A. Restriction Sign
• B. Manual Unlocking
• C. Force Resistance
• D. Winding Drums

Answer: (A)

Freight carriage restrictions are shown with a sign that uses a standard international prohibition symbol to communicate what is not allowed. A restriction sign conveys that certain loads or actions are not permitted on the equipment, and the pictogram is understood across languages, making the rule clear to everyone.

The other options don’t express a usage limitation: manual unlocking relates to how to release a mechanism, not to what can be carried; force resistance describes how much force the equipment can withstand, not an operational restriction; winding drums refer to a mechanical component rather than a safety restriction symbol.
