It is a very windy day. You are driving and a dust storm blows across the freeway reducing your visibility. You should drive slower and turn on your:
- Interior lights.
- Parking lights.
- Headlights. ✓
Answer: C. Headlights.
Slow down and turn on your headlights when a dust storm cuts your visibility on the freeway.
Why this is the answer
The handbook lists dust among the conditions that can keep you from seeing other vehicles, and it says to use headlights in adverse weather. Headlights serve two jobs: they help you see ahead and they help other drivers notice your car. That is why the right response to blowing dust is to reduce speed and switch on the headlights. The handbook also says driving with only parking lights is illegal, so that is not a substitute.
Why the other answers are wrong
- A. Interior lights. — The handbook does not list interior lights for driving in dust or adverse weather; it points to headlights for visibility.
- B. Parking lights. — The handbook says it is illegal to drive using only parking lights, so parking lights are not the right choice when dust reduces visibility.
Remember it
If dust, smoke, fog, or rain cuts your view, think headlights, not parking lights.
