Which statement about excessive speed and braking is MOST accurate?

• A. Excessive speed affects reaction time, not braking.
• B. Excessive speed can cause difficulties when braking.
• C. Excessive speed affects braking only when brakes are pumped.
• D. Excessive speed is dangerous but has no effect on braking.

Answer: (B)

The most accurate statement regarding excessive speed and braking is that excessive speed can cause difficulties when braking. When a vehicle is traveling at high speeds, the distance required to stop increases significantly due to the physics of motion. The faster a vehicle is moving, the more time and distance it will require to come to a complete stop. This is particularly critical in situations where sudden stops are necessary, as the increased speed can lead to a longer stopping distance, making it more challenging for the driver to react in time. Additionally, at higher speeds, the effectiveness of the braking system can diminish. The force of the collision will also increase if a driver is unable to stop in time, further compounding the dangers of operating a vehicle at excessive speeds. This understanding is essential for safe driving, as managing speed appropriately directly impacts a driver's ability to brake effectively and avoid accidents.
