Under what condition should you increase your following distance?

Increasing your following distance in poor weather conditions, such as rain or snow, is crucial for safety. Adverse weather can significantly affect road traction and visibility. In such conditions, vehicles may take longer to stop due to reduced grip on slippery surfaces, increasing the risk of collisions if a driver does not allow adequate space. By extending your following distance, you provide yourself with a larger reaction time to respond to any hazards or sudden stops by the vehicle in front of you, reducing the likelihood of rear-end accidents.

Driving in good weather or on straight roads generally does not necessitate an increased following distance, as the conditions are conducive to maintaining normal driving behaviors. Additionally, while higher speeds typically require more stopping distance, the primary focus in poor weather is on the diminished road conditions that warrant a more cautious approach.
