There are also some special plates. While the numbers and letters on standard licence plates are colored black, plates for foreign citizens permanently living in Croatia, international organizations and temporary registered vehicles have green numbers and letters. On the plates used on bigger
trucks and other vehicles that can be oversized for some of the smaller roads, the numbers and letters are red. The
police vehicles are equipped with the plates consisting of six numbers divided in two groups and separated by the coat of arms of Croatia, blue numbers. The first group of numbers denote the police department to which the vehicle belongs. While the background on all of these plates is colored white, on those used on
military vehicles it is yellow. However, the system of dividing numbers and letters is the same as on the standard plates, but instead of a city code there are letters HV for
Hrvatska vojska (
Croatian military). At the same time, specialized military vehicles have the letters VP for
vojna policija or MP for
military police (
military police) as the final two letters. Plates for diplomatic representatives (embassies, consulates) are blue with yellow numbers and letters. The first three number denote the country, followed by letter A, C, or M, then serial number of the vehicle. As opposed to all above mentioned plates that are made of metal, the dealer's test plates are stickers that are attached to the plate holder. These plates consist of a city code separated by the coat of arms from five numbers divided in two groups and they can be used for a limited number of days. Starting from 2008 onwards, special plates with an additional two letters (PP or PV) were introduced, PP stands for
prijenosne pločice (transferable plates) and PV stands for
povijesno vozilo (historical vehicle) in a form CC-PV-NNN(N). Also from 2008 onwards, export plates are introduced, with RH standing for Republika Hrvatska, and a green background with yellow numbers and letters. Croatia's Ministry of Internal Affairs proposed new licence plates with the EU stars. == City codes==
