What should you adjust as your vehicle's size and speed increase while following another vehicle?

As a vehicle's size and speed increase while following another vehicle, it is essential to increase your following distance. This practice allows for safer stopping distances, especially with larger or heavier vehicles that require more time and distance to come to a complete stop. The physics of motion indicates that higher speeds reduce reaction time and increase stopping distances, while larger vehicles can have greater momentum.

When following a vehicle at increased speed, maintaining or reducing the following distance could lead to a rear-end collision if the lead vehicle suddenly stops or slows down. By increasing the following distance, you have more time to react to the actions of the vehicle in front of you, making it a crucial aspect of safe driving, particularly in emergency situations. This principle is fundamental in emergency vehicle operation, where quick decision-making and safety are paramount.
