Which is a correct statement about stopping distances on dry and wet roads?

• A. Stopping distance is shorter on wet roads
• B. There is no difference in stopping distance
• C. Stopping distance is longer on wet roads
• D. It depends solely on the speed of the vehicle

Answer: (C)

Stopping distance is longer on wet roads due to the reduced friction between the tires and the road surface. When roads are wet, the water creates a film that can make it difficult for tires to grip the pavement effectively. This loss of traction leads to a longer braking distance as it takes more time for the vehicle to come to a complete stop. Additionally, factors such as the weight of the vehicle and the condition of the brakes can further influence stopping distances, but the key element here is the reduced friction on wet surfaces compared to dry roads. In contrast, stopping distances on dry roads are shorter because the tires can achieve maximum contact and grip, allowing for more effective braking.
