Which factors increase braking distance?

• A. Vehicle SIZE and SPEED
• B. Color and sound
• C. Engine displacement
• D. Weather only

Answer: (A)

Braking distance grows as you go faster and as the vehicle becomes heavier, because stopping requires dissipating more energy and overcoming more momentum. When speed doubles, the energy that must be removed increases roughly fourfold, so the distance to stop increases even more if braking capability stays the same. A larger, heavier vehicle has more momentum to overcome, so, under the same road and brake conditions, it tends to require a longer distance to reach a full stop.

Color and sound don’t influence braking performance, and engine displacement doesn’t directly affect how quickly you can stop once brakes are applied. Weather and road conditions do affect braking, but the factors highlighted here—speed and vehicle size—directly contribute to longer braking distances in typical EVOC contexts.
