You are riding a two-wheeled vehicle on a road with two lanes in each direction that is not an expressway (no exclusive lanes). Which statement about lane use is correct?
First decide whether a two-wheeled vehicle belongs to the left-lane or right-lane group on roads other than expressways (Annex 9 of the Enforcement Rule). The overtaking exception (Note 3) lasts only while overtaking, and where lanes are marked you must follow them (Article 14(2) of the Road Traffic Act).
Answer: ③
Explanation
On a two-lane road (each direction) other than an expressway, lane 1 is the left lane and lane 2 is the right lane, and two-wheeled vehicles belong to the right lanes, so their designated lane is lane 2 (Enforcement Rule Annex 9). When overtaking they may use lane 1, the lane immediately to the left (Note 3), but they may not stay in lane 1 when not overtaking. Where lanes exist, vehicles must follow the lanes, so riding between lanes is not allowed either (Road Traffic Act Article 14(2)).
