Final answer:
When driving in low visibility conditions and using windshield wipers, you must turn on your car's headlights to enhance visibility for yourself and for others on the road.
Step-by-step explanation:
When driving in low visibility conditions such as rain, fog, or smoke, and you have to use your windshield wipers, it is imperative that you turn on your headlights.
This action is not only for your own visibility but also to ensure that other drivers on the road can see your vehicle more clearly. In many places, it is actually a legal requirement to have headlights on when visibility is low and windshield wipers are in use.
The usage of headlights in such conditions enhances safety on the roads by increasing the visibility of your car to others, thereby reducing the risk of collisions. Remember, safety comes first, and it is crucial to adjust your driving according to the prevailing weather conditions.
