How does bad weather affect the 2-second rule in following distance?

Bad weather significantly impacts driving conditions, which necessitates an increased following distance for safety. In adverse weather situations, such as rain, snow, fog, or ice, visibility and road traction are compromised. When a driver is following another vehicle, they need more time to react to sudden stops or changes in speed, as stopping distances increase in slick conditions.

The 2-second rule is a guideline for maintaining a safe following distance under ideal driving conditions. In bad weather, this guideline should be adjusted to allow for at least a 5-6 second following distance. This extended distance provides the driver with additional time to process any hazards, make decisions, and execute maneuvers without risking a collision.

In summary, when faced with adverse weather conditions, increasing the following distance to 5-6 seconds is vital for maintaining safety on the road, as it allows for greater reaction time to unexpected events.
