What types of skid occur when the brakes are applied so hard that the front or rear wheels lose traction?

When brakes are applied too hard and wheels lose traction, two main types of skids can occur: front-wheel skid and rear-wheel skid. A front-wheel skid happens when the front wheels lose grip, causing the vehicle to slide straight ahead, often leading to understeering. In contrast, a rear-wheel skid occurs when the rear wheels lose traction, resulting in oversteering, where the rear of the vehicle swings out. Both types can compromise vehicle control and increase the risk of accidents.
