Final answer:
Under normal driving conditions, maintaining a safe following distance is crucial. Use the concept of following distance to ensure sufficient space between your vehicle and the one ahead of you to react and stop safely.
Step-by-step explanation:
Under normal driving conditions, you should use the concept of following distance to maintain a safe distance behind the vehicle in front of you. Following distance refers to the space between your vehicle and the vehicle ahead of you, which gives you enough time to react and stop safely if the lead vehicle suddenly brakes or encounters a hazard. The recommended following distance is three seconds.
To determine the following distance, choose a fixed point on the road, like a sign or a tree, and when the vehicle ahead of you passes that point, start counting. If it takes you three seconds or more to reach that point, then you have a safe following distance.
For example, if the car ahead passes the fixed point and you reach it after three seconds have passed, then you have maintained a safe following distance. However, if you reach the fixed point in less than three seconds, you need to increase your following distance.
