What is the most common cause of vehicle crashes?

The most common cause of vehicle crashes is driver error. This encompasses a wide range of mistakes made by the operator of the vehicle, including distracted driving, speeding, impaired driving (due to substances or fatigue), failure to obey traffic signals, and improper maneuvering. It's essential to recognize that human behavior plays a significant role in driving safety. While factors such as weather, mechanical issues, and road conditions can contribute to accidents, they are often secondary to the choices made by drivers. Understanding this highlights the importance of driver awareness and education in improving road safety and reducing the frequency of accidents.
