It provides vital context such as distance, duration, vehicle category, or exceptions. Always read this panel in conjunction with the primary sign to fully grasp the required behaviour and avoid misinterpreting traffic regulations, which is essential for both safe driving and passing your theory test.
This additional panel modifies main signs to specify exceptions, like excluding buses, which is crucial for accurate traffic rule interpretation. Mastering these nuances is key for your Italian driving theory test revision.

It changes the scope of the main sign by showing distance, length, time, vehicle category, exception, road condition, direction, or where a rule starts, continues, or ends. Ignoring the panel can make the main sign too broad or too narrow, so the complete sign assembly should be read before deciding. Official catalogue code: II.4-b.
The "The sign doesn't apply to the category shown (in the example buses )" panel modifies the main sign by adding scope information such as distance, length, time, category, exception, condition, direction, or start/end point. Catalogue code II.4-b.
