When should you increase your following distance?

Increasing your following distance is essential when traffic is heavy because this allows for safer braking and increased reaction time in case the vehicle in front of you suddenly stops or slows down. In heavy traffic, the risk of collision increases due to other drivers changing lanes or having a more unpredictable driving style. By maintaining a greater distance, you create a buffer zone, giving you more time to assess potential hazards and react accordingly.

In contrast, while riding in clear traffic might not necessitate a longer following distance, it's still a good practice to remain aware of your surroundings. Riding downhill typically presents different hazards, such as loss of traction or increased braking distance, but it does not inherently require an increase in following distance. Conditions like rain also demand a greater following distance due to decreased traction, but this is specific to environmental factors rather than the density of traffic.
