Until the legal reforms of 2006, official cars such as police, fire fighting and municipality vehicles did not carry a letter after the sticker, such as M-1234. These included: vehicles of the district government: 1-199, 1000-1999, 10000-19999 vehicles of the local government (for example: fire brigade): 200-299, 2000-2999, 20000-29999, 300-399 police: 3000-3999, 7000-7999, 30000-39999, 70000-79999 disaster relief (mostly changed to "THW", see above): 8000-8999, 80000-89999 This style of plate is no longer issued in most states, but many official vehicles which were registered before 2006 still carry this type of plate.
