What could result from not maintaining a safe following distance?

Answer: B — Increased possibility of rear-end collisions

Maintaining a safe following distance is crucial for safe driving, particularly with large vehicles. When a driver does not keep an adequate distance from the vehicle in front, the risk of rear-end collisions significantly increases. This is because a reduced following distance means the driver has less time to react to sudden stops or emergencies in front of them. Trucks require a longer stopping distance due to their weight and momentum, and without sufficient space, the driver may not be able to stop in time, resulting in a collision. This is a key aspect of defensive driving, ensuring that drivers have enough time to respond to unexpected changes in traffic conditions. Therefore, maintaining a safe following distance is a fundamental practice for preventing accidents and ensuring overall road safety.
