Road signs in Thailand

The Department of Railway maintains a standard on the typeface used in the sign, with custom made type for Thai text, unofficially named "Thang Luang" (อักษรทางหลวง) and a small derivation of FHWA Series fonts ("Highway Gothic") typeface, which is used on American road signage, for Latin text.

However, English is also used for important public places such as tourist attractions, airports, railway stations, and immigration checkpoints.

[citation needed] Thailand is the first country in Asia to adopt MUTCD standard yellow diamond warning signs, in 1940.

Those which express a prohibition (e.g., No Left Turn) show the pictogram crossed out by a red diagonal bar.

Road name signs in Thailand have different colours and styles depending on the local authority.

[8] Most road signs in Thailand use Thai (ภาษาไทย); the official and national language of that country.
