Why do heavy trucks leave large gaps in front of them?

• A. To provide space to stop the vehicle
• B. To save fuel
• C. To maintain speed
• D. To avoid other drivers

Answer: (A)

Heavy trucks need more time and distance to stop than smaller vehicles because of their overall weight and momentum. When the traffic ahead slows or stops, a loaded truck requires a much longer braking distance. Giving a larger gap in front provides the space and time to react and brake gradually, reducing the risk of a rear-end collision, especially in adverse conditions like wet roads or grades. This increased following distance is about safety and stopping ability, not about saving fuel, maintaining a constant speed, or avoiding other drivers. A four-second (or more, in poor conditions) following distance is often recommended for trucks to account for their longer stopping distance.
