Why is it important to maintain a larger following distance in adverse weather conditions?

Maintaining a larger following distance in adverse weather conditions is crucial primarily because it allows for more reaction time. When driving in rain, snow, or fog, the road conditions are often less predictable, and stopping distances can increase significantly. By extending the following distance, a driver can ensure they have ample time to react to sudden stops or emergencies from the vehicle ahead. This additional space provides a buffer that can help prevent collisions, particularly when roads are slippery or visibility is low.

In adverse conditions, vehicles are more likely to skid or hydroplane, and having more distance increases the chance to assess the road and any potential hazards effectively. This practice is part of defensive driving, where anticipating the actions of others and adjusting your driving accordingly can lead to safer outcomes.
