Which of the following conditions does NOT warrant increasing your following distance?

Increasing your following distance is crucial for safe driving under various conditions, as it provides more time to react to sudden changes in traffic. Clear and dry weather does not inherently pose risks that would necessitate increasing your following distance. In these conditions, drivers generally have better visibility and road traction, allowing them to maintain a regular following distance.

In contrast, driving at night can significantly impair visibility, making it harder to see obstacles or changes in traffic conditions. Following a motorcycle requires extra following distance since motorcycles can stop more quickly than vehicles and are less visible on the road. Similarly, towing a trailer affects a vehicle's dynamics, requiring additional space to account for the longer stopping distance and potential sway of the trailer. Therefore, while maintaining a safe distance is critical in various situations, clear and dry weather is the only scenario among the choices that does not warrant an increase in following distance.
