You are driving a truck and want to turn left at an intersection. This intersection has two left-turn lanes, lane 1 and lane 2. What is the correct way?
When there are two or more left-turn lanes, the lane division for roads other than expressways applies within those left-turn lanes as well (Annex 9, Note 7 of the Enforcement Rule). Treat the two left-turn lanes as a small road of their own and split them into a left and a right lane.
Answer: ③
Explanation
At an intersection with two or more left-turn lanes, vehicles must turn left within those lanes according to the lane division for roads other than expressways (Enforcement Rule Annex 9, Note 7). With two left-turn lanes, lane 1 is the left lane and lane 2 the right lane, so a truck turns left from lane 2. Lane 1 is for passenger cars and similar vehicles, and you must not turn left from a lane that is not a left-turn lane.
