What main cause of accidents is involved when Eileen was distracted by a text message?

Distractions while driving are a significant factor contributing to accidents, and in this scenario, Eileen's attention being diverted by a text message illustrates how human behavior can lead to unsafe driving conditions. The driver is ultimately responsible for maintaining focus on the road and their surroundings. When a driver is distracted, their reaction time is impaired, they may miss important signals, or fail to respond appropriately to other road users, increasing the likelihood of accidents.

In this context, while road conditions, vehicle issues, and weather can also contribute to accidents, they are not the primary issue here. The core problem is Eileen's distraction resulting from her choice to engage with her phone, highlighting the critical importance of driver attention and awareness in road safety. Therefore, the driver’s actions and decision-making process directly relate to the risk of accidents in this case.
