In dense fog on an expressway when visibility is less than 100 meters, you must turn on your headlights, side marker lights, tail lights, and other lights while driving.

Answer: False

Explanation

The Rules of the Road specify that the standard for turning on headlights and other lights in tunnels or dense fog is when you cannot see 50 meters ahead on regular roads, and when you cannot see 200 meters ahead on expressways. The correct distance is 200 meters, not 100 meters.
