Subsidiary signs

What do subsidiary signs look like?

Subsidiary signs are square with a white background and black text. What's special about subsidiary signs is that they only apply when used together with a main sign. The subsidiary sign clarifies what the main sign means and where it applies.

Is the trailer fitted out for camping use and towing vehicle subsidiary sign important for the theory test and the driving test?

This sign is relevant for the theory test because it is important to understand that caravans and towing vehicles have their own rules. For the driving test it is less relevant, since the test is carried out without a trailer for class B. Even so, it is part of the curriculum, and you should have a basic understanding of it.

What does the trailer fitted out for camping use and towing vehicle subsidiary sign mean?

The "trailer specially fitted out for camping use, together with any towing vehicle" subsidiary sign is used to show that a rule or information on the main sign applies specifically to caravans and the vehicles that tow them. This symbol is often placed under signs such as parking signs or prohibition signs to make clear which vehicles the rules apply to. For example, it can be used to reserve parking spaces for caravans or to prohibit them in an area. The symbol makes it easy for drivers to understand which rules apply to their vehicle.

If the subsidiary sign is used together with the text "Except", it means that caravans and towing vehicles are not covered by the rules on the main sign. This can be useful in situations where caravans are given special permissions, such as parking in areas with restrictions for other vehicles.
