What happens if the brakes lock during a skid?

When brakes lock during a skid, the vehicle's tires lose traction with the road surface, which significantly reduces the driver's ability to steer. This loss of traction means the vehicle will likely continue to slide in the direction it is already moving, often resulting in a loss of control. In this situation, the driver cannot effectively maneuver the vehicle, increasing the risk of a crash or collision. It's crucial for drivers to learn techniques such as threshold braking or pumping the brakes to help maintain control during skids, emphasizing the importance of avoiding locked brakes whenever possible.
