Which of the following factors could increase braking distance?

Braking distance is influenced by various factors that affect the vehicle's ability to stop effectively. Wet roads can significantly reduce tire traction, causing vehicles to slide rather than stop quickly. When the road surface is slick due to rain, water can create a thin film between the tires and the pavement, which decreases friction. This condition means that even if brakes are applied with the same amount of pressure, the vehicle will take longer to come to a complete stop as compared to dry roads.

While other factors like distraction, fatigue, and alcohol also impact driver reaction times and decision-making, they do not directly alter the physical distance required for braking under normal conditions. Distraction may delay the reaction to apply brakes, fatigue can slow reactions, and alcohol impairs judgment and coordination, but the wetness of the road surface itself directly affects how effectively the brakes can operate, making it a critical factor in increasing braking distance.
