Ch. 6 · 第３節 夜間
Even during the day, when passing through places such as inside tunnels or thick fog where you cannot see 100 meters ahead, you must turn on your headlights.
[True / False · Medium]
Answer: False
Explanation
The Rules of the Road section "2. Lights (1)" clearly states "even during the day, when passing through places such as inside tunnels or thick fog where you cannot see 50 meters ahead (200 meters on expressways)." The question states "100 meters," which is incorrect.
