Which rule is considered the best for following distance?

The Three-Second Rule is regarded as the best for following distance because it provides a safe amount of time to react to unexpected situations on the road. This rule states that a driver should maintain at least three seconds of time between their vehicle and the one in front of them. This time span allows for adequate space to brake or avoid a sudden obstacle, particularly in variable driving conditions such as rain or heavy traffic.

Using the Three-Second Rule can be particularly effective because it accounts for human reaction time, which can be delayed in stressful situations. By measuring this distance in seconds rather than feet, drivers can better adjust their following distance according to their speed and road conditions, ensuring greater safety.

This time frame is generally seen as a good balance: it is long enough to allow for safe stopping while still keeping traffic flowing efficiently. In comparison, shorter intervals might not provide adequate reaction time, while longer intervals can lead to situations where drivers become hesitant or risk being cut off by other vehicles.
