Staying a recommended distance from other vehicles while experiencing hydroplaning is essential for ensuring safety on wet roads. During hydroplaning, a vehicle can lose contact with the road surface, making it difficult to steer or brake effectively. Keeping a distance of four car lengths allows for adequate space to react to sudden changes in traffic, such as other vehicles losing control or needing to stop abruptly.

This distance can help provide a buffer zone that minimizes the risk of collisions as drivers navigate through the reduced traction conditions created by standing water on the roadway. By maintaining this distance, drivers give themselves extra time to slow down, regain control, or maneuver safely without the risk of rear-ending the vehicle in front of them.

While other options suggest varying distances, four car lengths strike a balance between maintaining a safe distance and allowing for practical maneuverability on the road.
