Warning sign Italy. Reflective sign for overhanging loads. The sunny south awakens the desire for extensive road trips. In doing so, people like to take various items with them in the car, such as bicycles or surfboards. But beware: In Italy and Spain, it is legally required to mark overhanging loads with a metal sign. The aluminum warning sign helps you comply with this requirement in a straightforward way. To switch between the two countries, you simply need to flip the striped warning sign. Note: The widely used plastic warning signs in Germany may cause issues in Italy and Spain, as metal signs are required there.
