What is the recommended following distance behind another vehicle?

The recommended following distance behind another vehicle is 3-4 seconds. This duration allows a driver sufficient time to react to sudden stops or emergencies from the vehicle ahead. Measuring following distance in seconds provides a consistent and practical way to ensure that you are maintaining a safe space, regardless of the speed at which you are traveling. This time frame takes into account the average stopping distance and helps reduce the likelihood of collisions by giving you adequate time to respond to changes in the traffic situation.

In certain conditions, such as wet or icy roads, a longer following distance may be prudent. While the other options suggest shorter distances, they may not allow enough reaction time, particularly at higher speeds or in situations where stopping abruptly is necessary. Thus, adhering to the recommended 3-4 seconds helps enhance road safety for you and others.
