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

Increasing following distance during heavy snowfall is particularly important due to the reduced traction and visibility that significantly impair vehicle handling and stopping distance. Snow and ice can cause road surfaces to become slippery, increasing the likelihood of skidding. When the road conditions are compromised, a longer following distance allows greater reaction time to safely maneuver or stop in case the vehicle in front suddenly brakes or is involved in an incident. Additionally, visibility may be reduced due to falling snow, making it harder to judge distances accurately. Thus, maintaining a larger buffer helps ensure safety for both the driver and others on the road when facing poor weather conditions.
