When passing a large truck, why shouldn't you cut in front too quickly?

The key reason for not cutting in front of a large truck too quickly is the issue of stopping distance. Trucks are significantly larger and heavier than passenger vehicles, which means they require a longer distance to come to a complete stop. If you merge in front of a truck too rapidly, you risk creating a situation where the truck does not have sufficient space to stop safely if needed. This can lead to dangerous scenarios, including rear-end collisions if the truck driver needs to brake suddenly.

Understanding stopping distance is critical, as it varies between different types of vehicles. Trucks, in particular, have a higher momentum and need more time to decelerate due to their weight. Hence, ensuring there is enough room between your vehicle and the truck in front after passing is essential for maintaining safety on the road.
