Question

driving on an icy road will affect your:
headlights
tire alignment
stopping distance
vision

Explanation:

Icy roads reduce tire traction, which directly increases the distance needed to bring a vehicle to a complete stop. The other options are not directly affected by icy road surfaces: headlights function independently of road conditions, tire alignment is a mechanical setting unrelated to ice, and vision is only indirectly impacted by ice (e.g., glare) but not a direct effect of driving on icy roads.

Answer:

stopping distance
