What effect does applying the brakes during a skid have on the vehicle?

Applying the brakes during a skid can indeed upset the vehicle's balance. When a driver engages the brakes while skidding, it can transfer more weight and disrupt the stability of the vehicle, which may lead to a loss of traction and further exacerbate the skid. This disruption can cause the vehicle to become more difficult to control, making it more likely to veer off course or spin, especially if the brakes are applied abruptly or excessively.

In circumstances where traction is already compromised, the braking force can lead to a greater slip angle, meaning that the direction in which the vehicle is heading can become misaligned with the direction in which the wheels are pointed. This misalignment increases the likelihood of a complete loss of control. Therefore, maintaining smooth steering and avoiding sudden braking are crucial when trying to regain control of the vehicle during a skid. The other answers do not accurately describe the most common consequences of braking during a skid.
