Which statement is true about stopping distance for heavy vehicles?

• A. Weight has no effect on stopping distance
• B. Heavier vehicles stop faster
• C. Fully loaded trucks take longer to stop
• D. Stopping distance is shorter on wet roads

Answer: (C)

Heavy vehicles have more momentum, so the heavier the load, the more energy brakes must absorb to slow down. This means the braking distance grows as weight increases, and a fully loaded truck takes longer to stop than an empty one. Road conditions matter too: wet pavement reduces tire grip, making stopping even longer. So the true statement is that fully loaded trucks take longer to stop. The other options aren’t correct because weight does affect stopping distance; heavier vehicles do not stop faster; and stopping distance is not shorter on wet roads.
