What is a good rule for determining the distance you should follow behind another car?

Keeping at least two seconds of distance behind another vehicle is a recommended practice because it allows for a safe following distance under normal driving conditions. This time frame provides an adequate buffer to react to sudden changes, such as when the vehicle in front of you brakes unexpectedly.

By counting two seconds from the moment the rear of the vehicle ahead passes a fixed point, you can better gauge your distance and adjust your speed accordingly. This rule is particularly important in maintaining safety, as it helps avoid tailgating, which increases the risk of rear-end collisions.

While following distances can vary based on road conditions, weather, and vehicle type, the two-second rule is generally a good starting point for most drivers. In adverse conditions, such as rain or fog, extending the following distance is advisable to ensure greater safety.
