In European countries vehicle registration plates usually have black lettering on a white background. Which country's plates have red lettering?
Belgium can be called a unique country for several reasons. It appears that one of these reasons is the Belgium system of vehicle registration plates.
Belgian number plates have a white background with red numbers and letters, while other European countries use only black letters.
This might be interesting: The country was one of the last EU member states to have red letters on their numbers plates. There have been a lot of discussions on the topic, but finally, it was decided to preserve the red-on-white scheme. However, a darker shade of red is used on Belgium number plates nowadays. Another interesting thing is that Belgium number plates are also driver specific: if a Belgian buys a new car, he or she has to attach his old number to it.
