Comparison of MUTCD-influenced traffic signs

[1] Other non-American countries using road signs similar to the MUTCD include Australia, Indonesia, Ireland, Japan, Malaysia, New Zealand, and Thailand.

There are also a number of American signatories to the Vienna Convention on Road Signs and Signals: Argentina, Brazil, Chile, Cuba, Ecuador, French Guiana, Paraguay, and Suriname.

[2] However, UN compliant signs must make use of more pictograms in contrast to more text based US variants.

Unlike in Europe, considerable variation within road sign designs can exist within nations, especially in multilingual areas.

(In non-English speaking countries, English is frequently included on signs near airports and tourist areas.)
