Massachusetts Permit Practice Test

Locked wheel skids are typically caused by braking too hard at high speeds. When a driver applies the brakes forcefully, especially if the brakes are applied suddenly without allowing enough stopping distance, the wheels can lock up. This means that instead of turning and maintaining traction with the road, the wheels stop rotating and slide on the surface. This loss of traction causes the vehicle to skid in the direction it is moving, making it difficult for the driver to steer and regain control. When considering the other options: accelerating quickly can lead to loss of traction as well but doesn't specifically relate to wheel lock-up. Turning sharply at low speeds generally doesn’t cause a locked wheel skid either; rather, it might lead to understeering or oversteering, depending on various factors. Driving on slippery surfaces can contribute to skids in general, but locked wheel skids at high speeds are predominantly a result of excessive braking force when the vehicle's wheels cannot maintain grip.
