Ch. 6 · Hazardous Areas

In fog or blizzards, you should turn on fog lights if available, or headlights if not, early.

[True / False · Easy]

Answer: ✓ True

Explanation

Chapter 6, Section 4 of the Rules of the Road states: "Fog and blizzards severely limit visibility. If you have fog lights (light yellow auxiliary headlights), turn on fog lights; if not, turn on headlights early." Early lighting is necessary because visibility becomes severely limited.

In fog or blizzards, I guess I should turn on lights early if I have them?

Misaki

That's correct. Use fog lights if you have them, or headlights if you don't—visibility gets severely limited, so early lighting is essential.

So it's not just about seeing, but being seen too?

Misaki

Exactly. In thick fog or snow, other drivers need to spot you just as much as you need to see the road.
