What should be your following distance in adverse weather conditions?

Answer: B — 2 to 4 seconds

In adverse weather conditions, maintaining a following distance of 2 to 4 seconds is essential for ensuring safety on the road. This increased distance allows for more reaction time in case of sudden stops or changes in traffic flow, which are more likely in conditions such as rain, snow, or fog. When visibility is compromised or the road surface is slippery, vehicles take longer to stop. Therefore, a longer following distance provides an additional buffer that can help prevent collisions. This range gives drivers the flexibility to adjust their distance based on specific circumstances, like driving speed and the severity of the weather conditions. It is important to recognize that normal following distances may not be sufficient in adverse conditions, where any form of distraction or unexpected event can lead to accidents.
