You are driving a passenger car in the daytime on a road covered in thick fog. What is the most appropriate use of lights?
💡 Hint
In fog, rain, or snow you must turn on your lights even in the daytime (Article 37(1)2 of the Road Traffic Act), and the lights a motor vehicle must use are listed in Article 19(1) of the Enforcement Decree. Check whether interior lights or hazard lights count as those lights.
Answer: ③
Explanation
Article 37(1)2 of the Road Traffic Act requires lights when there is fog, rain or snow, day or night, and Article 19(1)1 of the Enforcement Decree lists headlights, sidelights, taillights and license plate lights for motor vehicles. In fog it matters not only that you can see ahead but that others can see you. An interior light or hazard lights alone do not meet the legal requirement.
