What does sign B2 indicate about vehicles?

The sign indicated by B2 specifies that vehicles with a mass of 10 tons and less are not permitted to enter that particular area. This sign is crucial for maintaining traffic flow and ensuring safety, as it restricts access to larger vehicles that may cause congestion or be unsuitable for certain roads or zones, such as narrow streets or residential areas. The restriction is particularly important in areas where there may be weight limitations due to the structural integrity of the road or bridge, ensuring that only vehicles that adhere to those guidelines are allowed. Understanding this rule can help drivers identify suitable routes and comply with local traffic regulations, promoting safety and efficiency on the roads.
