How does increasing tire traction affect vehicle stopping distance?

Increasing tire traction decreases stopping distance because enhanced traction allows the tires to grip the road surface more effectively. When a vehicle's tires have better traction, they can exert more force against the road while braking. This increased friction between the tire and road helps the vehicle to decelerate more rapidly, thereby shortening the distance needed to come to a complete stop.

Good tire traction is particularly important in various conditions, including wet or icy roads, where even slight increases in grip can make a significant difference in how quickly a vehicle stops. In contrast, when traction is poor, such as on slippery surfaces, stopping distances tend to increase because the tires are unable to hold onto the road effectively, resulting in longer stopping distances.

The other options do not accurately represent the relationship between tire traction and stopping distance. Options that suggest an increase or no effect are contrary to the fundamental principles of physics regarding friction and motion. A nuanced understanding of road conditions is applicable but doesn’t negate the fact that increased traction generally leads to shorter stopping distances.
