You are driving in lane 2 when car A ahead suddenly stops. Car B is approaching from behind in lane 1. Which TWO are correct? Select TWO
- Your car (blue) is driving in lane 2
- Car A ahead suddenly stops
- Car B approaching from behind in lane 1
The basic rule is to keep a distance that lets you avoid a collision even if the vehicle ahead stops suddenly (Article 19(1) of the Road Traffic Act). People often forget that swerving into the next lane in an emergency is also a lane change, which is not allowed if it may obstruct a vehicle coming in that lane (Article 19(3)).
Answer: ②, ④
Explanation
When the car ahead stops suddenly, brake first to avoid a collision; that is why you must always keep a safe distance from the car ahead (Road Traffic Act Article 19(1)). Swerving into the next lane is also changing lanes, so you must not move if it may obstruct car B coming in that lane (Article 19(3)). Steering away without checking or crossing the centerline can lead to a worse crash.
