Expressways in South Korea
Expressways in South Korea were originally numbered in order of construction. Since August 24, 2001, they have been numbered in a scheme somewhat similar to that of the Interstate Highway System in the United States; the icons of the South Korean Expressways are notably similar to those in the United States because they are shaped like U.S. Highway shields and colored like Interstate shields with red, white and blue, the colors of the flag of South Korea.
- Arterial routes are designated by two-digit numbers, with north-south routes having odd numbers, and east-west routes having even numbers. Primary routes (i.e. major thoroughfares) have 5 or 0 as their last digit, while secondary routes end in other digits.
- Branch routes have three-digit route numbers, where the first two digits match the route number of an arterial route.
- Belt lines have three-digit route numbers where the first digit matches the respective city's postal code.
- Route numbers in the range 70–99 are not used in South Korea; they are reserved for designations in the event of Korean reunification.
- The Gyeongbu Expressway kept its Route 1 designation, as it is South Korea's first and most important expressway.

Since June 1, 1972, all motorcycles except police motorcycles are prohibited from driving on expressways in South Korea, regardless of engine displacement. Before 1972, motorcycles with an engine displacement greater than 250 cc were permitted on expressways.
Since March 15, 1992, all motorcycles except police motorcycles have been banned from certain other roads designated for motor vehicles only. These roads are marked by a circular blue sign with a white silhouette of a car.
South Korea is the only country in the OECD with a freeway ban on motorcycles.
