Which statement about motor vehicle lights is NOT correct?
Lights must be on not only at night but also in tunnels and in fog (Article 37(1) of the Road Traffic Act), and you must adjust the direction and brightness of your lights so as not to hinder other drivers (Article 20 of the Enforcement Decree). Think not only about oncoming vehicles but also about following the car ahead.
Answer: ③
Explanation
Article 20 of the Enforcement Decree requires drivers following directly behind another vehicle at night to point headlights downward and not to manipulate their brightness in a way that hinders the vehicle ahead, so using high beams on it is wrong. Article 37(1) of the Road Traffic Act requires lights not only at night but also in tunnels and in fog, and you must dim or lower your lights for oncoming traffic.
