Austria’s transport minister wants to amend the country’s Motor Vehicle Act to ban license plates with coded Nazi messages, UPI reported.

Minister Alois Stoger said some license plates have been found to contain coded Nazi messages, such as the use of "18" for the initials of Adolf Hitler and "88" to symbolize the Nazi greeting "Heil Hitler."

“The far-right scene keeps developing new codes," said ministry spokeswoman Andrea Heigl. "The legislative branch must watch out for these trends."

Stoger, a member of Austria’s Social Democrat Party, said Monday he intended to add Nazi and neo-Nazi-related codes and symbols to the list of banned license plates, which currently covers "ridiculous or offensive" number and letter combinations.

The new regulations, which are likely to come into effect during the summer, would also ban "SS" and "NSDAP," which stands for the National Socialist German Workers' Party.
