A direction signboard.

Road signs in Thailand are standardized road signs similar to those used in other nations but with certain distinctions. Until the early 1980s, Thailand closely followed American, Australian and Japanese practice in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. Signs usually use the FHWA Series fonts (Highway Gothic) typeface also used in the United States, Though some signs on recently completed expressways use Transport Heavy (cf. the second image shown to the right).

Thai traffic signs use Thai, the official and national language in Thailand. However, English is also used for important public places such as tourist attractions, airports, railway stations and immigration checkpoints. Both Thai and English are used in the direction signs.
