In the daytime, a minor collision on an expressway has left your car unable to continue, although the car itself has not broken down. Which judgment about the breakdown warning sign is correct?
💡 Hint
A breakdown warning sign must be set up whenever you can no longer drive on an expressway or similar road "due to a breakdown or any other reason" (Article 66 of the Road Traffic Act). Do not read it narrowly as applying only to breakdowns because of its name, and also recall where it must be placed (Article 40(3) of the Enforcement Rule).
Answer: ②
Explanation
Article 66 requires the breakdown warning sign when a vehicle becomes undrivable on an expressway due to 'a breakdown or other reason', so a collision is included. Under Enforcement Rule Article 40(3), the sign is placed where drivers approaching from behind can see it. Delaying it or leaving it to the other driver increases the risk of a secondary accident.
