What is the safe driving distance in adverse weather conditions?

In adverse weather conditions, such as rain, snow, or fog, decreasing visibility and traction can greatly impact stopping distances and reaction times. Therefore, it is essential to increase the following distance beyond the recommended three seconds under normal conditions. This allows for extra time to react to unexpected stops or hazards, giving the driver ample space to brake safely without risking a collision.

When conditions are poor, a greater distance provides a buffer against skidding or hydroplaning, which are more likely in such weather. The idea is to allow for additional time to respond to any changes in traffic or conditions, as roads may be slick and vehicles may take longer to stop than usual. This practice enhances safety for both the driver and others on the road.
