When is it necessary to give extra following distance?

Giving extra following distance in poor weather conditions is crucial for maintaining safety on the road. Adverse weather such as rain, snow, fog, or ice can significantly reduce vehicle traction and visibility. This makes it more likely for vehicles to skid or for drivers to misjudge distances. By increasing the following distance, a driver provides themselves with more time and space to react to any potential hazards, reducing the risk of collisions.

In poor weather, stopping distances can double or even triple compared to dry conditions due to reduced grip on the road and impaired visibility. Hence, allowing extra space in these situations accounts for longer stopping distances as well as the increased likelihood of sudden stops by other vehicles. It plays a vital role in defensive driving, ensuring that the driver has enough time to respond to unforeseen circumstances safely.
