You want to enter a roundabout and leave by the road straight ahead. Car A is approaching in the circulating lane from the left, and car B is following close behind you. Which TWO are correct? Select TWO
- Your car (blue) is about to enter the roundabout and leave by the road opposite (at the top)
- Car A is approaching your entry in the circulating lane from the left
- Car B is following close behind you
A vehicle about to enter a roundabout must drive slowly or make a temporary stop and yield to vehicles already circulating (Article 25-2(2) of the Road Traffic Act). This order does not change even if the car behind is tailgating, and sudden braking without unavoidable cause is prohibited (Article 19(4)).
Answer: ②, ④
Explanation
A vehicle entering a roundabout must slow down or come to a temporary stop and yield to car A, which is already circulating (Road Traffic Act Article 25-2(2)). Rushing in because the car behind is close could cause a collision with A, so it is safest to brake early in several steps and slow down gradually so the driver behind notices in advance. You must not brake suddenly except to prevent danger or when unavoidable (Article 19(4)), so sudden braking on purpose as a warning is wrong.
