During what conditions is it especially important to increase following distance?

Increasing following distance during poor weather conditions is crucial for several reasons. Reduced visibility and traction can dramatically affect a vehicle's stopping distance. Rain, snow, fog, or ice can make roads slippery, leading to potential skidding or longer distances required to stop safely. Additionally, poor weather can cause other drivers to behave unpredictably or with reduced performance, increasing the likelihood of needing to react quickly. By allowing a greater following distance, you provide yourself with more time to respond to sudden changes in conditions or to the actions of other drivers, thereby enhancing your overall safety on the road.

In contrast, under conditions such as dry weather, good visibility, daylight, or while driving in a city, the need for increased following distance is generally less critical since road conditions and other factors are more predictable and manageable.
