What does the term "fishtailing" indicate about a vehicle?

The term "fishtailing" describes a situation where a vehicle's rear end begins to swing out to one side or the other during operation, typically due to oversteering or loss of traction. This indicates that the vehicle is experiencing a loss of control, as the driver is unable to maintain a straight path and the back of the vehicle moves unpredictably.

In adverse conditions, such as wet or icy roads, fishtailing can occur if a driver accelerates too quickly or takes a turn too sharply. Recognizing fishtailing is crucial for drivers, as it is a clear signal that they need to adjust their driving habits to regain control of the vehicle. Understanding this concept helps ensure safety on the road, particularly in challenging driving conditions.

The other options imply either stability and proper functioning of the vehicle or suggest safety, which contradicts the scenario that fishtailing represents.
