Which of the following statements about overtaking is correct?
As a rule, overtaking is done on the left of the vehicle ahead, and you must also watch oncoming traffic while overtaking (Article 21 of the Road Traffic Act). The vehicle being overtaken also has a duty not to interfere. If you memorize only the rule, it is easy to miss the exception allowed for certain vehicles, so sort it out by vehicle type.
Answer: ④
Explanation
Article 21(1) of the Road Traffic Act requires overtaking on the left of the vehicle ahead, but paragraph 2 lets bicycles and personal mobility devices pass on the right of a slow-moving or stopped vehicle, while watching out for people getting in or out. Overtaking drivers must also pay full attention to oncoming traffic (paragraph 3), and a vehicle being overtaken must not speed up to race (paragraph 4).
