Characters on 4D plates, in contrast to flat standard plates, have raised or embossed borders which give them a three-dimensional aspect. For it to produce this effect, elements are layered to form a border surrounding the characters, giving them a stunning and appealing appearance.

  • Character Colour: While the majority of 4D plates continue to employ the conventional black characters, certain variations might employ different colours, this could be in contradiction with the need for black on white or black on yellow.
  • Materials & Reflectivity: The 4D plates’ needed reflectivity & durability could be impacted by the usage of numerous layers.
  • Flag and Identifiers: The EU flag and nation identifier could be obscured or covered by 4D plates.

Penalties And Enforcement
