Final answer:
Managing space when driving means managing the distance between your car and the vehicle in front of you. It is important to maintain a safe following distance, which can be determined using the 3-second rule.
Step-by-step explanation:
The recommended safe distance to maintain between cars is called the following distance. It is important to keep enough following distance to allow for reaction time in case of sudden stops or emergencies.
To determine the following distance in car lengths, you can use the 3-second rule. Choose a fixed object on the road (like a sign or tree) and start counting when the vehicle in front of you passes it. If you reach that object before you finish counting to three, you are following too closely and should increase your distance.
For example, if you counted to three when the vehicle in front of you passed a sign, and you passed the sign before you finished counting, you would need to increase the distance. On the other hand, if you finished counting to three before passing the sign, you are maintaining a safe following distance.
