Final answer:
Oversteer occurs when a car's rear tires lose grip, and to correct it, a driver must countersteer. Countersteering involves turning the wheels opposite to the direction of the skid and is essential for vehicle control.
Step-by-step explanation:
If you have not corrected the oversteer by countersteering, the car will continue to spin. Oversteer is a term used in vehicle dynamics to describe a situation where a car turns (steers) more than the amount commanded by the driver. During oversteer, the rear tires lose grip before the front tires, causing the rear end of the car to slide outwards. Countersteering is the act of steering the vehicle's front wheels in the opposite direction of the skid to regain control and prevent the car from spinning. It is a critical skill in driving, particularly in high-performance or emergency situations.
