What is the term for when the front of a car fails to respond correctly to the steering wheel?

Understeering is the term used when the front of a car fails to respond correctly to the steering input from the driver. This situation occurs when a vehicle does not turn as sharply as intended, causing the front wheels to lose traction while the driver attempts to steer.

In practical terms, when a driver turns the steering wheel, the desired direction is not achieved, resulting in the car continuing straight even as the steering input indicates a turn. This is more common in vehicles with front-wheel drive, where power is being sent to the front wheels while also necessitating that they steer. When the front tires lose grip, the vehicle's ability to follow the intended path is compromised, often leading to a wider turning radius than expected.

Understanding understeering is crucial for driving instructors as it informs both teaching strategies for handling turns and maneuvers, as well as highlights the importance of maintaining vehicle control and awareness of road conditions that contribute to traction loss.
