Final answer:
In ideal driving conditions, a minimum following distance is recommended to ensure safe braking and reaction time.
Step-by-step explanation:
In ideal driving conditions, a minimum following distance is recommended. The following distance refers to the distance between your car and the car in front of you. This distance allows you to have enough time and space to react and stop safely in case the car in front of you suddenly brakes or stops. A general rule is to maintain a following distance of at least three seconds, which is equivalent to the time it takes for your car to pass a fixed object after the car in front of you passes it. For example, if the car in front of you passes a signpost, you should count how many seconds it takes for your car to pass the same signpost. If it takes less than three seconds, you should increase your following distance.
