You are driving in lane 2 of an expressway and want to change to lane 3. When must you start signaling with the right turn signal?
💡 Hint
A turn signal must start at a set distance before the point where you act, and that distance differs between general roads and expressways (Article 21 and Appendix 2 of the Enforcement Decree of the Road Traffic Act). Signaling as you turn the wheel is too late, and do not mix up the two numbers.
Answer: ③
Explanation
When changing course to the right while going in the same direction, you signal from at least 30 m before that point, but on an expressway from at least 100 m (Enforcement Decree Article 21, Appended Table 2, item 2). Speeds are higher on expressways, so following drivers need more time to notice. Signaling while turning the wheel or after crossing the lane line is too late.
