You want to change from lane 2 to lane 1 on a road with two lanes each way. Two-wheeled vehicle A is coming up fast from behind between lanes 1 and 2. Which TWO are correct? Select TWO
- Your car (blue) wants to change from lane 2 to lane 1 (left turn signal on)
- Two-wheeled vehicle A is coming fast from behind between lanes 1 and 2
You must not change lanes if it may obstruct a vehicle coming from the direction you want to move into (Article 19(3) of the Road Traffic Act). A turn signal gives you no priority, and a small two-wheeled vehicle can easily hide in your mirror's blind spot.
Answer: ①, ④
Explanation
You must not change lanes if it may hinder the normal travel of a vehicle coming in that direction (Road Traffic Act Article 19(3)). A two-wheeled vehicle riding between lanes is small and easily hidden in your mirrors' blind spot, so turn your head to check directly, and change lanes with your turn signal on after A has gone by (Article 38(1)). Relying only on your turn signal, or braking suddenly for no reason of danger prevention (Article 19(4)), is wrong.
