When driving on the road at night, which vehicle must turn on its interior light in addition to the headlights, sidelights, tail lights and license plate light?
💡 Hint
The basic lights a motor vehicle uses at night are the same, but interior lights are additionally required only for certain types of vehicles that carry passengers (Article 19(1)1 of the Enforcement Decree of the Road Traffic Act). Sort them by whether the vehicle is private or commercial, and whether it carries people or cargo.
Answer: ③
Explanation
Enforcement Decree Article 19(1)1 lists headlights, sidelights, tail lights, license plate light and interior light for motor vehicles at night, but the interior light applies only to buses and to passenger cars used in passenger transport business (such as taxis). Private cars and trucks have no interior-light duty, and a motorcycle uses only a headlight and tail light.
