Which of the following is a common cause of driver inattention?

Texting while driving is a significant cause of driver inattention because it requires visual, manual, and cognitive engagement. When a driver sends or reads a text message, their attention is diverted from the road, creating a dangerous situation that can lead to accidents. This form of distraction dramatically increases the risk of collision, as it takes the driver's focus away from the task of driving, which requires continuous attention to the surrounding environment.

Other actions, such as using turn signals, adjusting mirrors, or maintaining a safe following distance, are essential parts of safe driving and typically require only brief moments of attention. These actions are designed to enhance safety and contribute to effective communication with other road users. In contrast, texting prolongs distraction and can compromise a driver's ability to respond promptly to changing conditions on the road.
