You are driving a lorry. Which of the following factors should you take into account to keep a safe distance from the vehicle in front?

The speed of the vehicle is a key factor that determines the total stopping distance, which consists of the reaction distance and the braking distance. As speed increases, the distance required to stop the vehicle safely increases sharply. In the case of a lorry, due to its large mass, maintaining a following distance appropriate to its speed is particularly important for safety.
