Ch. 6 · Hazardous Areas

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.

Close, but that's false. The rule says 50 meters, not 100—200 meters on expressways.

Oh, the distance was wrong!

Exactly. Remember: 50 meters for regular roads, 200 for expressways.
