Which of the following is a sign of hydroplaning?

Feeling a loss of steering control is a clear indicator of hydroplaning. When a vehicle hydroplanes, it means that the tires have lost contact with the road due to a layer of water on the surface. This loss of traction prevents the driver from being able to steer effectively, which might lead to feeling unresponsive to steering inputs. This experience can cause panic, as the vehicle moves without direction, making it critical for drivers to understand this warning sign to take preventive measures, such as slowing down and avoiding sudden movements during wet conditions.

In comparison, hearing a loud noise or feeling a sudden jolt does not specifically relate to hydroplaning and can be associated with other mechanical issues or road conditions. Seeing a police vehicle is irrelevant to the experience of hydroplaning, as it does not convey any information about vehicle control or road conditions.
