National, provincial, county and township road signs

The national highway sign begins with the letter G, followed by three numbers, indicating the national highway. Although the expressway also begins with the letter G, it is followed by one or two digits.

Dart: Road signs are usually yellow and black, starting with the letter S, followed by three numbers. The meaning of this number is similar to that of highways and national highways. The first digit 1 represents the radial provincial road from the provincial capital, 2 represents the north-south direction of the provincial road, and 3 represents the east-west direction.

County road: it is mainly the reason for connecting the county seat and the county seat (town), and it is also the letter X after adding three digits. From the color point of view, the county road signs are black and white.
