About this plate: MOTORFAHRRAD (moped) plates, governed by their own article rather than by the Art. 71/72 scheme. Four things set them apart and all four are statutory: a portrait 100x140 mm format, MANDATORY yellow reflective material, NO coat of arms, and an integral insurance vignette. The five-digit width is the only digit count the Liechtenstein ordinance states anywhere.
Separators: The moped plate's layout is different again: Art. 82 Abs. 6 puts FL at the TOP with the insurance vignette beside it and the five digits BELOW, on two lines. The pattern spells a space for the break.
