Define "oversteering" in the context of driving emergency vehicles.

Oversteering refers to a driving condition where the driver turns the steering wheel too much in relation to the vehicle's actual trajectory. This excessive turning can lead to a situation where the rear end of the vehicle begins to slide out, making it difficult to maintain control. In the context of emergency vehicle operations, understanding oversteering is crucial because emergency vehicles often drive in high-pressure situations where quick turns may be necessary. However, if a driver oversteers, it can result in a loss of control, leading to potential accidents or hazards not just for the emergency vehicle but for others on the road as well. This means mastering steering inputs is essential for safe and effective emergency response driving.
