Most skids are caused by_________.

The correct answer emphasizes that the majority of skids are a result of driver error. This reflects the importance of driver behavior and decision-making in maintaining control of a vehicle. Factors such as excessive speed, sudden turns, or abrupt braking can lead to loss of traction, particularly in slippery conditions.

Although weather conditions, tire pressure, and road conditions can contribute to the likelihood of a skid, they are often exacerbated by the driver's actions. For instance, a driver might choose to accelerate too quickly in wet weather or fail to adjust their driving technique to suit adverse road conditions. Recognizing that driver error is a primary cause highlights the critical role that responsible driving practices play in preventing skids and ensuring road safety.
