Why is it important for following vehicles to keep space in front of a large truck?

• A. To accelerate the truck
• B. To allow time to stop if the truck slows or stops
• C. To save fuel
• D. To reduce road glare

Answer: (B)

Giving yourself space in front of a large truck means leaving enough following distance so you have time to react and stop if the truck slows or stops. Large trucks weigh a lot, so they require more distance to brake than cars. Their stopping distance is longer, and on wet or icy roads it’s even greater. If you’re too close, a sudden slowdown by the truck can leave you with no time to stop and you could crash into it. By keeping a safe gap, you can see the truck’s brake lights sooner and have time to brake gradually, reducing the chance of a rear-end collision. The other ideas don’t address the safety risk of not having enough time to stop when a heavy vehicle ahead slows or stops.
