All three signs in the image prohibit the access of vehicles with a width greater than 2.30 m, but in different ways:

Sign 1 (“Traffic prohibited in both directions”) prohibits the access of all vehicles, regardless of size or type. Therefore, the access of those with a width over 2.3 m is also automatically prohibited.

Sign 2 is specific: it prohibits the access of only vehicles with a width greater than 2.30 m, therefore it applies strictly according to gauge.

Sign 3 prohibits the access of motor vehicles (that is, any motor vehicle intended for road travel) and animal-drawn vehicles. Therefore, if a motor vehicle has a width greater than 2.30 m, its access is in any case prohibited by the fact that it is a motor vehicle, regardless of width. It does not mean that sign 3 regulates width, but that vehicles wider than 2.30 m, if they are motor vehicles or animal-drawn, in any case fall under its prohibition.

Therefore, even if only sign 2 directly refers to width, all three signs have the effect of prohibiting the access of vehicles wider than 2.30 m, which is why all answer options are correct.
