In bad weather conditions like fog, what should you maintain?

Maintaining a greater following distance between your vehicle and others in bad weather conditions, such as fog, is essential for safe driving. Reduced visibility can significantly affect your ability to judge distances and react to sudden changes in traffic conditions. By increasing the distance, you provide yourself with more time to respond to any potential hazards, such as a vehicle stopping unexpectedly or debris on the road.

In fog, where visibility can often drop to very low levels, having a greater following distance allows for necessary stopping time. As vehicles may take longer to stop on slippery or wet surfaces, this added space can be crucial in preventing collisions. Additionally, when driving in fog, it's common for vehicles ahead to become visually obscured, so the additional distance gives you a buffer to assess the situation clearly.

In contrast, maintaining a shorter following distance can lead to dangerous situations where the driver does not have adequate time to react, potentially resulting in accidents. Similarly, suggesting that there is no requirement for following distance ignores the basic need for safe driving practices in challenging conditions, while maintaining a constant speed without regard to conditions is likely to lead to loss of control over the vehicle.
