Article 1
These Regulations are defined in accordance with Article 33-6 of the Statute Governing Road Traffic (hereinafter referred to as the Statute). 
 
Article 2
The definitions of the terms used in the Regulations are as follows:
1. Freeways: Freeways are defined as having entries and exits completely controlled and roads centrally divided with traffic going in opposite directions on either side. Freeways intersect with other roads except for their starting and ending points. They are exclusively used by automobiles.
2. Expressways: In addition to freeways, expressways are those roads whose entries and exits are controlled, in whole or in part, and whose roads are centrally divided. Expressways intersect with other main roads except for their starting and ending points and may link with secondary roads. They are exclusively used by automobiles.
3. Main Traffic Lanes: Main traffic lanes are those which serve automobiles.
4. Outer Lanes: Outer lanes are the outer right lanes of the main traffic roads.
5. Inner Lanes: Inner lanes are the inner left lanes of the main traffic lanes.
6. Middle Lanes: Middle lanes are the middle lanes of the three or five lanes headed in the same direction.
7. Middle Outer Lanes: Middle outer lanes are the lanes adjacent to the outer lanes of the four or five lanes headed in the same direction.
8. Middle Inner Lanes: Middle inner lanes are the lanes adjacent to the outer lanes of the four or five lanes headed in the same direction.
9. Acceleration Lanes: Acceleration lanes are found between the ramps and main traffic lanes. They are the lanes where automobiles accelerate before going from the ramps to the main traffic lanes.
10. Deceleration Lanes: Deceleration lanes are found between the ramps and main traffic lanes. They are the lanes where automobiles decelerate before going into the ramps from the main traffic lanes.
11. Auxiliary Lanes: Auxiliary lanes are the outer lanes of the main traffic lanes. They connect the acceleration lane and deceleration lanes of the two neighbouring interchanges. Auxiliary lanes are exclusively used by automobiles entering and leaving freeways and expressways.
12. Interchanges: Interchanges are the intersections consisting of ramps that connect with freeways, expressways or other roads.
13. Ramps: Ramps are the interconnections between acceleration/deceleration lanes, main traffic lanes and other roads within interchanges.
14. Climbing Lanes: Climbing lanes are the outer lanes of the upward sloping main lanes. This is where automobiles travel at speeds below the minimal requirements.
15. Central Reserves: Central reserves are the central diving zones that separate two-way traffic lanes.
16. Road Shoulders: Road shoulders are the outer lanes of traffic lanes or the areas between road margins and road fences or road drainages.

Freeways and expressways mentioned in the first and second paragraphs are announced by the competent authorities governing Freeway of the central governments. If necessary, the expressways not connecting freeways may be opened to large and heavy motorcycles after the governing authorities obtain approval from the competent authorities governing Freeway at the central governments.

The vehicles running on the intersections between expressways and secondary roads are not subject to these Regulations when they pass through the secondary roads.
