At night, a two-wheeled vehicle is forced to stop on the road because of a breakdown. Which light must be on in this case?
💡 Hint
The lights that must be on when stopping or parking on a road at night differ by vehicle type (Article 19(2) of the Enforcement Decree). Distinguish the standard for two-wheeled vehicles and motorcycles from that for other motor vehicles, and consider whether a light that dazzles other drivers is needed while stopped.
Answer: ②
Explanation
Under Enforcement Decree Article 19(2)2, two-wheeled vehicles and motorcycles must have the taillight (including the rear reflector) on when stopped or parked on the road at night. Other motor vehicles need both taillights and sidelights, so the rule differs. A high-beam headlight only dazzles other drivers and is not the light required when stopped.
