Answer:
C
Step-by-step explanation:
In any situation when it is difficult to see the road ahead of you, it is important to turn on your headlights so that you can see more clearly. This is important during weather storms, nighttime driving and when smoke is blocking your view.
It is also important to reduce your speed, because in case your headlights do not provide the best visibility, this makes sure that if you are involved in a collision, it is not at a speed that will be lethal.
