A rear-wheel skid occurs when the rear wheels of a vehicle lose traction, causing the back end to slide sideways. This can happen during sharp turns, sudden acceleration, or when driving on slippery surfaces like ice or wet roads. When the rear wheels skid, the driver may feel a loss of control, making it difficult to steer the vehicle. To regain control during a rear-wheel skid, drivers should steer into the direction of the skid. This means turning the steering wheel in the same direction the rear of the vehicle is sliding. Proper techniques and awareness can help prevent accidents related to rear-wheel skids.
