The Commission also noted that the use of languages in road signage is regulated by the Vienna Convention on Road Traffic of 8 November 1968, which came into effect on 11 December 1992 but was not signed by all the Member States.
Komisija je tudi navedla, da uporabo jezikov pri cestnih oznakah ureja Dunajska konvencija o cestnem prometu z dne 8. novembra 1968, ki je začela veljati 11. decembra 1992, vendar je niso podpisale vse države članice.
