Overview of road signage in Cambodia
Road signs in Sihanoukville
Road signs in Cambodia (Khmer: ឧបសម្ព័ន្ធស្តីពីសញ្ញាចរាចរផ្លូវគោក) are standardized road signs are similar to those used in Europe but much of it resembles road signage systems used in South American countries with certain differences. The designs of road signage match their neighbours of Thailand and Malaysia, both of which adopt a modified version of the South American road signage system (despite both Thailand and Malaysia being part of Asia). Until the early 1980s, Cambodia closely followed American, European, Australian, and Japanese practices in road sign design, with diamond-shaped warning signs and circular restrictive signs to regulate traffic. Unlike Thailand and Malaysia, Cambodia does not use the FHWA Series fonts ("Highway Gothic") typeface, favouring Helvetica instead.
Cambodian traffic signs use Khmer, the national language of Cambodia, however, English is also used for stop and important public places such as tourist attractions, airports, railway stations, and immigration checkpoints. Both Khmer and English are used on directional signage. Cambodia signed the Vienna Convention on Road Signs and Signals, but has yet to ratify the convention.
