What is the safe following distance in adverse weather conditions?

In adverse weather conditions, such as rain, snow, or fog, it is crucial to maintain a safe following distance to ensure adequate time to react to any unexpected changes on the road. A following distance of four seconds or more allows drivers the necessary time to brake safely and avoid collisions, especially when traction may be reduced due to slick road surfaces.

Weather can significantly impact visibility and the vehicle's stopping distance. By extending the following distance to four seconds, drivers create a buffer that accounts for these variables. This longer distance gives them more time to identify potential hazards and respond appropriately, such as slowing down or stopping, without risking a rear-end collision.

In contrast, shorter following distances like two or three seconds may not provide sufficient time to react in tricky driving conditions, where stopping distances are increased and visibility is compromised.
