Which of the following may travel on an expressway?
💡 Hint
Only motor vehicles may use an expressway, and among them two-wheeled vehicles are allowed only when they are emergency vehicles (Article 63 of the Road Traffic Act). First check whether motorcycles and electric bicycles count as "motor vehicles" under the law.
Answer: ④
Explanation
Article 63 bans vehicles other than motor vehicles, and pedestrians, from traveling on or crossing expressways, and allows two-wheeled vehicles only if they are emergency vehicles. Motorcycles and bicycles are not motor vehicles and may not enter, and neither may two-wheeled vehicles that are not emergency vehicles.
Legal basis: 도로교통법 제63조
