Road signs in Sri Lanka are standardized to closely follow those used in Europe with certain distinctions, and a number of changes have introduced road signs that suit as per local road and system. Sri Lankan government announced by a gazette that aimed to get a facelift and introduction of over 100 new road traffic signs. The new change will be replaced in colour and sizes and introduction of Variable-message sign & electronic digital sign boards in express highways. The Japanese government has granted LKR 1.24 billion to implement message signs in expressways.^[1]

Language applicable traffic sign boards are in Sinhalese, Tamil and English. The motor traffic act (chapter 203) describes road traffic signs.^[2]
