The majority of collisions are caused by what primary factor?

Collisions predominantly occur due to drivers' failure to adjust to existing conditions. This includes factors such as weather, road conditions, visibility, and traffic patterns. When drivers are unable to adapt their speed and behavior in response to these variables, the likelihood of an accident increases significantly. For instance, in adverse weather conditions like rain or snow, if a driver does not reduce their speed or increase their following distance, they may not have sufficient time to react, resulting in a collision.

While mechanical failure, aggressive driving, and poor road infrastructure are important factors that can contribute to accidents, they are not the primary causes compared to the critical role of a driver's response to current conditions. Many accidents can be avoided simply by being aware of and adjusting to the environment, highlighting the need for awareness and adaptive driving practices.
