Final answer:
To maintain a safe driving distance, use the 3-second rule.
Step-by-step explanation:
To maintain a safe driving distance between your car and the car in front of you, you should use the 3-second rule. This means that you should keep a distance of at least 3 seconds between your car and the car in front of you.
To use the 3-second rule, choose a fixed point on the road, such as a sign or a tree. When the car in front of you passes that point, start counting. If you reach the same point before you finish counting to 3, then you're following too closely and need to increase your following distance.
By using the 3-second rule, you allow yourself enough time to react to any sudden changes in traffic or road conditions, reducing the risk of collisions.
