Road signs in Thailand
Overview of road signs in Thailand / From Wikipedia, the free encyclopedia
Road signs in Thailand are standardized road signs similar to those used in other nations but much of it resembles road signage systems used in South American countries with certain differences, such as using a blue circle instead of a red-bordered white circle to indicate mandatory actions.[1] Until the early 1980s, Thailand closely followed American, European, Australian, and Japanese practices in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. 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.[2] In most Bangkok Metropolitan Area's routes, TS Lopburi is still used.
Thai traffic signs use Thai, the national language of Thailand, and distances and other measurements are expressed in compliance with the International System of Units. However, English is also used for important public places such as tourist attractions, airports, railway stations, and immigration checkpoints. Both Thai and romanizations are used on directional signage.
Thailand is a signatory to the 1968 Vienna Convention on Road Signs and Signals, but has yet to fully ratify the convention.[3]
