Final answer:
Pulling in too closely in front of a truck is risky due to a truck's longer stopping distance. Trucks need more time and distance to halt, so cutting in front may not give a truck driver enough room to stop and avoid a collision safely.
Step-by-step explanation:
It is not advisable to pull in closely in front of a truck after passing it due to the larger distance and time it takes for a truck to come to a stop compared to smaller vehicles. Trucks have a longer stopping distance because of their mass and size. When a driver covers a certain distance before hitting the brakes, the overall stopping distance is a combination of that initial distance traveled and the distance the truck covers after applying the brakes. If a vehicle cuts closely in front, the truck driver may not have sufficient space to stop without causing a collision. Therefore, maintaining a safe following distance and ensuring there is ample space after passing is crucial for road safety.
