The Road Safety signs you see on New Zealand roads are transnational emblematic signs. This means they use the same shapes and symbols as business signs each over the world. Emblematic signs are used because they're quick to read and easy for all motorists to understand. New Zealand’s signs are generally made of reflective material, making them easier to read at night.
