Initiating a controlled stop on slippery surfaces requires an understanding of how to manage vehicle dynamics to prevent loss of control. Gradually applying the brakes and using steady pressure is essential because it allows the driver to modulate the braking force, reducing the risk of wheels locking up and causing the vehicle to skid. This method helps maintain traction between the tires and the slippery surface, which is critical for safe stopping.

In contrast, applying the brakes abruptly can lead to a loss of traction, increasing the likelihood of a skid. Shifting to a lower gear may help slow the vehicle down through engine braking but is less effective than proper brake application on slick surfaces. Steering sharply to regain traction can also lead to a loss of control, as it could destabilize the vehicle further on slippery conditions. Therefore, slowly and steadily applying the brakes is the best practice for maintaining control and ensuring a safe stop.
