The sign "Prohibition for vehicles over the specified actual axle load" indicates that vehicles exceeding a certain axle load specified on the sign are not allowed to enter or pass through that area. This is usually put in place to protect roads, bridges, or specific areas that cannot support heavier vehicles.

The weight limit is typically shown as a number on the sign, measured in kilograms. It's important for drivers to heed this sign to avoid damage to infrastructure and to ensure their vehicle complies with legal load limits. Violating this prohibition can lead to fines or damage to road surfaces, which can affect safety for everyone.
